We have an in-house test facility to measure acoustic properties of speed, attenuation and relative contrast. In addition, two ultrasound systems are used to visually inspect each phantom. As a result, every ultrasound phantom is subjected to rigorous testing both during manufacture and upon completion.

Page 5: Instructions For Use
If the scanning surface becomes damaged, seal the phantom in an airtight container and IMMEDIATELY contact CIRS for return authorization. Call 800-617-1177, email at rma@cirsinc.com or fax RMA Request form to 757-857-0523. -
Page 6: Use Of Removable Water Well And Covers
For curved arrays, the water well may be attached and filled with water to provide better coupling. Side Fire transducers can be particularly chal- lenging to scan with a standard phantom. CIRS has designed a removable endo- cavity cover for these transducers. When this accessory is attached, the phantom should be placed on its back and the cover should be filled with water. -
Page 7: General Guidelines For Performing Measurements
If not, then the conclusions drawn may not be valid. CIRS recommends that you use the most commonly set- tings for the type of probe tested- i.e. the liver preset values for an abdominal... -

4. Frequency of system assessment: How often each system is evaluated is also up to each facility to deter mine. CIRS recommends at least annually. Reference the accreditation programs established by the ACR and AIUM at www.acr.org or www.aium.org for further guidance on establishing a QA program. -
Page 9: Perimeter, Area And Volume Measurements
DISTANCE (CONT) Align the probe so that all the vertical targets are displayed at their maximum intensity level. Freeze the image and obtain a hard copy. Using electronic calipers, measure the distances between two wires at various depths or align the echoes to the display markers for comparison. Record these measurements. -
Page 10: Uniformity Testing
To calculate a surface area or volume, an image is taken at a particular scan plane. Using the calipers, the dimensions of the 2D shape are taken and the area is deter- mined using the system’s algorithms. Next, perform a 3D scan of the line targets with the scan planes parallel to each other and the scan direction perpendicular to the axes of the line targets. -
Page 11: Depth Of Penetration
DEPTH OF PENETRATION TESTING Depth of penetration, also called maximum depth of visualization or sensitivity, is the greatest distance in a phantom for which echo signals caused by scattering in the background material can be detected on the display. The depth of penetration is determined by the frequency of the transducer, the attenuation of the medium being imaged and the system settings. -
