The field engineers are required to announce every remote connection to a system previously by calling the affected site.
Disruptive Mode: If the field engineer requires unrestricted access to the ultrasound system the field engineer requests for disruptive mode on the system. A message appears on the screen asking for permission to switch to disruptive mode: GE Service is requesting permission to diagnose the system remotely. Normal system operations might be disturbed during this period. If disruptive mode is accepted, work on the system can be disturbed severely. Therefore, it is not allowed to perform an exam or make a diagnosis using the ultrasound system while being in disruptive mode.
Therefore, it is recommended to cease work on the system as soon as the field engineer contacts the site and announces the remote connection. Network Security: The remote access features enables, after checkout has been performed, network services like ftp or telnet on the ultrasound system. Therefore, it is advisable to restrict network access to system for unauthorized personnel. It is strongly recommended to use a firewall to restrict network access from and to an ultrasound system with the remote access feature installed.
Other precautions like a secure network segment are encouraged. Given its known benefits and recognized efficacy for medical diagnosis, including use during human pregnancy, the American Institute of Ultrasound in Medicine herein addresses the clinical safety of such use: No confirmed biological effects on patients or instrument operators caused by exposure at intensities typical of present diagnostic ultrasound instruments have ever been reported.
Although they indicate that the benefits to patients of the prudent use of diagnostic ultrasound outweigh the risks, if any, that may be present. Please note: Prudent use means that the ultrasound machine is to be used by the operator in accordance with the ALARA principle, i. An ultrasound bioeffect is any biological mechanism or process that is produced, triggered or catalyzed by exposure to ultrasound. One can differentiate two known mechanisms for the development of bioeffects when humans are exposed to ultrasound: the thermal effect of ultrasound and the cavitation.
With humans no harmful bioeffects due to exposure to diagnostic ultrasound have been noticed. The rise in tissue-temperature under the influence of ultrasound energy is called thermal effect. The level of the temperature rise depends mainly on the following parameters: the irradiated quantity of energy, the surface of exposure and the thermal characteristics of the tissue.
Regarding the thermodynamics, the AIUM-report comes to the following conclusions:. Note that the thermal model of the AIUM does not take into account the influence of tissue blood circulation. Cavitation concerns the reaction of gas- or vapor bubbles or gas- or vapor accumulations present in tissue or liquids.
Transient cavitation means dilatation and quick collapsing of a bubble as a reaction to one or more ultrasound pulse beams. This quick collapse can lead to locally limited in micrometer range high temperatures and pressures. Stable cavitation concerns the repeated oscillation of a bubble. This bubble oscillation can have effects on neighboring cells, especially due to transverse action acting on its membrane and due to disturbance of the contained cytoplasma.
Amplitude and frequency of the bubble oscillation are dependent on the bubble size at the beginning and resonance frequency characteristics as well as on frequency and pressure of the impinging ultrasound. With tissue of mammals the scientists came to contradictory results regarding the ability to produce cavitation. This is possibly due to differences in the occurrence of cavitation germs bubbles.
Very little is known about the factors determining the presence or absence of micro bubbles, their chemical consistence and visco-elastic characteristics. The results of cavitation tests also depend on ambient pressure, on the acoustic energy and the pressure level. With the output power used in diagnostic ultrasound no cavitation was observed in vivo. With the limited data available it is not possible to specify threshold values for the pressure amplitude at which – when using diagnostically relevant pulse lengths and pulse repetition frequencies – cavitation occurs with mammals.
Some scientists observed that the peak rarefaction pressure pr of the transmitted disturbance is related closer to occurrence of cavitation than to the overall measured peak pressure due to compression plus rarefaction. Other examinations showed that the peak rarefaction pressure of the basic oscillation component of the disturbance could be among the three mentioned parameters the most closely related to the cavitation.
All intensity parameters are determined by measurement in water. As water does not absorb the acoustic energy, these measurements in water represent the most unfavorable value. In biological tissue however the acoustic intensity is absorbed.
The “real” value in a given position depends on the amount and type of tissue through which the ultrasound beam passes and on the ultrasound frequency. The value in tissue in situ can be approximately determined with the following formula:. As the ultrasound generally crosses tissue layers of different thickness and different types on its way through the body during an examination, it is very difficult to estimate the real intensity in situ.
For reports generally an impedance coefficient of 0. The value in situ that is generally indicated in reports is calculated according to the following formula:. As this value must not be considered as the real intensity in situ, the term “recalculated” is used hereunder. In some cases the max. Recalculated value and the max. Value in water do not occur under the same operating conditions.
Therefore the max. Values in water and recalculated max. Values mentioned in reports may not be related according to the above-mentioned formula. For example: An array probe with multiple focusing, whose max. Intensity values in water are lying in the deepest focal zone; for this zone, however, the smallest recalculating factor is valid. With the same probe the highest recalculated intensity can be lying in one of the focal zones closest to the surface. The FDA has laid down limits for the max.
Therefore the recalculated intensities are brought to the highest possible value with the help of the system controls when the output power is tested. Under all operating conditions the point of the max. Recalculated intensity can be closer to the probe than the point of the max.
Intensity in water; it will never be further away from the transducer. Please refer to this standard to get further information on this matter.
Thermal Index TI is a quantity related to calculated or estimated temperature rise under certain defined assumptions. Bone Thermal Index TIB is the thermal index for applications, such as fetal second and third trimester or neonatal cephalic through the fontanel , in which the ultrasound beam passes through soft tissue and a focal region is the immediate vicinity of bone. Cranial Bone Thermal Index TIC is the Thermal Index for applications, such as pediatric and adult cranial applications, in which the ultrasound beam passes through bone near the beam entrance into the body.
Mechanical Index MI formula is the spatial-peak value of the peak rare factional pressure, derated by 0. To make the MI unitless, the right-hand side of the equation below is multiplied by [ 1 0.
Scanned mode auto-scanning is the electronic or mechanical steering of successive ultrasonic pulses or series of pulses, through at least two dimensions. Unscanned mode nonautoscanning is the emission of ultrasonic pulses in a single direction, where scanning in more than one direction would require moving the transducer assembly manually.
These values are not defined on the basis of the ultrasound bioeffects, but are based on the output power of instruments, that were manufactured prior to the modification of FDA- Regulations Thermal models in development in include the output power.
The limit for MI is 1. In some cases the tissue can be exposed to sound and intensity values that are higher than those given recalculated for in situ. In these cases the reported values in situ do not represent the worst case of exposure. But this case occurs only if the tissue has an attenuation coefficient below 0. While scanning, notice the index numbers you are using and which controls affect the readings.
Try to keep the index numbers as low as you can, while maintaining diagnostic information within the image. This is particularly important when scanning the fetus. The display accuracy of the mechanical index and all thermal indices is 0. Values below 0. Following the ALARA principle means to keep the total ultrasound exposure as low as reasonably achievable, while optimizing diagnostic information. With the new ultrasound equipment, the output display lets us determine the exposure level in terms of the potential for bioeffects Controlling the total exposure depends on output level and exposure time.
The output level required for an exam depends on the patient and on the clinical need. Not all diagnostic exams can be performed at very low levels. In fact, using too low levels may result in poor data and the need to repeat the examination. Using too high a level may not increase the quality of the information, but it will expose the patient to unneeded ultrasound energy.
Primarily, it’s our training, education, and experience that determine how quickly we can obtain a useful image, and thus, the length of the exam and the amount of exposure. So, the question is ‘How much time do we need to obtain the desired diagnostic information? GE Medical Systems-Kretztechnik Ultrasound therefore recommends careful studying of the system’s manual to become familiar with the operating controls and output display of the system as well as with following the ALARA principle.
This might decrease the risk of any potential biological hazard caused by ultrasound exposure during an examination! W0 : is the ultrasonic power, except for TISscan, in which case it is the ultrasonic power passing through a one-centimeter window mill watts. For MI, zsp: is the axial distance at which pr.

The phantom is designed and constructed by Ernest L. Madsen, Ph. This 3D ultrasound phantom contains two sets of spherical targets. All spherical targets in the same set a have coplanar centers and the same diameter and identical contrasts over the total depth of 15cm. The center-to-center separation between adjacent spheres is 0.
Madsen’s phantom. This pertains only high contrast large targets i. This pertains only low contrast large targets i. NOTE: The resolution in orthogonal, reconstructed plane is considerably lower than that of the primary scan plane.
The system resolution is particularly lower for low contrast targets in the reconstructed, orthogonal plane. Significant system artifacts may exist in the orthogonal plane parallel to the face of the probe. For the reason of improved lateral resolution you should choose the proper scanhead for the depth range of the structure to be measured.
The instrument does not pose any unusual threat when disposing of it. Description of the System The vast array of probes makes it suitable for many applications. The operation is designed for the specific clinical requirements and ensures simple and efficient handling. Vast ranges of measuring and evaluation programs, as well as many special functions enable comfortable working. Under the provision of regular maintenance by authorized service personnel, the life expectancy is 7 years from the manufacturing date.
The biological effects of diagnostic ultrasound on the human body have not been entirely investigated yet. So far no damages by ultrasound diagnosis are known, still the instrument should only be used by a medical doctor or under his supervision.
The ultrasound examination should be performed in as short of a time as possible and with the lowest transmit power available to enable diagnostic results ALARA principle, As Low As Reasonably Achievable. The occurring sound intensities depend on the respective probes. The declaration of sound field parameters acc. One distinguishes between two acting mechanisms for the development of Bioeffects when exposing the human body to ultrasound waves: Heat Generation and Cavitation.
Heat generation: the ultrasound energy is absorbed by the tissue and warms it up, the amount of heat depending on the absorbed power and duration of exposure. A part of the heat is dissipated into the blood stream. Cavitation: due to a strong negative pressure gas bubbles appear. The permanent change between gas and liquid phase constitute strong local mechanical stress in the tissue. The degree of cavitation is influenced by the gas content and the superficial tension of the tissue resp.

It is a general purpose, mobile, software controlled diagnostic ultrasound scanner. Its function is to acquire ultrasound data and to display the data of different modes. In addition to the initial operational settings for each transducer pre-programmed in the system, user- customized parameter settings for each transducer may be inserted by the operator and stored for recall as needed via the system control panel.
System configuration is stored on the hard drive and all necessary software is loaded from the hard drive on power up. Biopsy guidelines are provided on screen to assist in the collection of tissue samples, using biopsy guide adapters offered as an optional accessory. The system provides the ability to perform remote viewing of images without compression, via DICOM 3.
High-resolution images are provided by utilizing a technology called digital dynamic receive focusing.
It is used for location and measurement of anatomical structures and for spatial orientation during operation of other modes. In 2D-mode, a two-dimensional cross-section of a three-dimensional soft tissue structure such as the heart is displayed in real time. Ultrasound echoes of different intensities are mapped to different gray scale or color values in the display.
The outline of the 2D cross-section may be a rectangle, parallelogram, sector or degree circle, depending on the particular transducer used. It is used primarily for cardiac measurements such as value timing on septal wall thickness when accurate timing information is required.
M-mode is also known as T-M mode or time-motion mode. Ultrasound echoes of different intensities are mapped to different gray scale values in the display. M-mode displays time motion information of the ultrasound data derived from a stationary beam.
Depth is arranged along the vertical axis with time along the horizontal axis. M-mode is normally used in conjunction with a 2D image for spatial reference. The 2D image has a graphical line M-line superimposed on the 2D image indicating where the M-mode beam is located. The 2D cross-section may be presented as a rectangle, parallelogram, trapezoid, sector, or a full circle, depending on the particular transducer used. Often, to provide spatial orientation, the full color blood flow cross-section is overlaid on top of the grayscale cross-section of soft tissue structure 2D echo.
For each pixel in the overlay, the decision of whether to display color Doppler , gray scale echo information or a blended combination is based on the relative strength of return echoes from the soft tissue structures and from the red blood cells.
Blood velocity is the primary parameter used to determine the display colors, but power and variance may also used. A high pass filter wall filter is used to remove the signals from stationary or slowly moving structures.
Tissue motion is discriminated from blood flow by assuming that blood is moving faster than the surrounding tissue, although additional parameters may also be used to enhance the discrimination.
Color flow can be used in combination with 2D and Spectral Doppler modes. The 2D cross-section is presented as a full color display, with various colors being used to represent the power in blood flow echoes. Often, to provide spatial orientation, the full color blood flow cross-section is overlaid on top of the gray scale cross-section of soft tissue structure 2D echo.
For each pixel in the overlay, the decision of whether to display color Doppler power , gray scale echo information or a blended combination is based on the relative strength of return echoes from the soft-tissue structures and from the red blood cells.
The power in the remaining signal after wall filtering is then averaged over time persistence to present a steady state image of blood flow distribution. In spectral Doppler, blood flow is presented as a scrolling display, with flow velocity on the Y-axis and time on the X-axis. The presence of spectral broadening indicates turbulent flow, while the absence of spectral broadening indicates laminar flow. PW Doppler provides real time spectral analysis of pulsed Doppler signals.
This information describes the Doppler shifted signal from the moving reflectors in the sample volume. PW Doppler can be used alone but is normally used in conjunction with a 2D image with an M-line and sample volume marker superimposed on the 2-D image indicating the position of the Doppler sample volume.
The sample volume size and location are specified by the operator. Sample volume can be overlaid by a flow direction cursor which is aligned, by the operator, with the direction of flow in the vessel, thus determining the Doppler angle. PW Doppler also provides the capability of performing spectral analysis at a selectable depth and sample volume size.
These 3D images are useful in visualizing three-dimensional structures, and in understanding the spatial or temporal relationships between the images in the 2D sequence. The 3D image is presented using standard visualization techniques, such as surface or volume rendering. The acquisition of volume data sets is performed by sweeping 2D-scans with special transducers called 3D-transducers designed for the 2D-scans and the 3D-sweep.
Images are spatially registered, using internal probe position sensing and a position control to ensure geometric accuracy of the 3D data. For example in 2D gray scale imaging, a 2 dimensional cross-section of a 3-dimensional soft-tissue structure such as the heart is displayed in real time. Typically, the user of an ultrasound machine manipulates the position and orientation of this 2D cross-section in real time during an ultrasound exam.
By changing the position of the cross-section, a variety of views of the underlying structure are obtained, and these views can be used to understand a 3-dimensional structure in the body. To complete survey a 3-dimensional structure in the body, it is necessary to collect 2D images which span a volume containing the structure.
One way is to sweep the imaging cross-section by translating it in a direction perpendicular to the cross-section. Another example method is to rotate the cross section about a line contained in the cross section. The Voluson Ultrasound System uses the automated so called C-Scan for the motion perpendicular to automated B-scan. Once a representative set of 2D cross-sections are obtained, standard reconstruction techniques can be used to construct other 2D cross-sections, or to view the collection of the cross-sections as a 3D images.
The mathematics behind this feature is called 3D-rendering. Such combined images are called projections, because the data from the volume is projected onto a flat 2-dimensional surface e. This technique can be applied to any 2D ultrasound mode. Several techniques can be used to aid the human observer in understanding the resulting 2D image as a representation of a three-dimensional object.
One is to rotate the volume of data, and present the resulting sequence of 2D projections to the observer. The changing direction of observation helps the observer to separate the features in the volume according to their distance from the observer. The gray value for each pixel of the 2D-image is calculated from the voxels along the corresponding projection path analyzing beam through the volume.
The render calculation algorithm, surface or transparent mode, determines how 3D-structures are visualized. Mot CCM Ser. ScanConverter f. Power, Stdby, etc.
Multibeam-DeInterleave means: Incoming Pixel order shot1pix1-shot2pix1-shot3pix1-shot4pix1 – shot1pix2-shot2pix2-shot3pix2-shot4pix The second method of THI is pulse-inversion: 2 TX-Beams are shot to the same Tissue- location, one with positive, one with negative polarity. The subtraction of both shots Subtraction Filter brings to bear the nonlinear-echo-reflection-properties of the tissue especially in usage of Contrast-medias , which is very useful with extremely difficult-to-image patients.

PC will always incline to sputter. In Real Time 4D mode the volume acquisition box is at the same time the render box. All information in the volume box is used for the render process. By freezing the acquired volumes, size can be adjusted, manipulated manually as known from the Voluson 3D Mode.
All other workstations can be adapted individually. The advantage in comparison with other imaging methods is the real- time display, quick availability and easy access to any desired region of the patient.
The 4D biopsy allows for real time control of the biopsy needle in 3D multi-planar display during the puncture. The user is able to see the region of interest in three perpendicular planes longitudinal, transversal and frontal section and can guide the biopsy needle accurately into the centre of the lesion. It allows completely new possibilities in cancer diagnosis, therapy planning and follow-up therapy control. Shell Imaging – construction of a virtual shell which covers the entire contour to separately calculate internal tumor vascularization and peripheral vascularization for tumor therapy planning and follow up control.
It is not a Real Time 4D technique, but a post processed 3D acquisition. Between three and nine beams are correlated to form one image line. The advantages of Compound Resolution Imaging are enhanced contrast resolution with better tissue differentiation and clear organ borders. Also vessel walls and tissue layers are emphasized for easier recognition.
The TD image provides information about tissue motion direction and velocity. This image results from a special rendering mode consisting of texture and transparency information. VCI improves the contrast resolution and therefore facilitates finding of diffuse lesions in organs. This information describes the Doppler shifted signal from the moving reflectors in the CW Doppler beam. CW Doppler can be referenced through a small pencil probe or phased array scan head, but it can also be used in conjunction with a 2D image which has an M-line superimposed on the 2D image indicating the position of the Doppler sample volume.
For through-the-beamformer CW, this beam is steerable by the operator, and is done by adjusting the location of the M-line. The CW Doppler beam, or M-mode line, can be steered allowing interrogation along an operator-selected line within the image. Probeboard CPR Beamformer. Gen r Gen. Bus Beamformer Blockschaltbild.
