IEC Technical Standard 62736. CIRS is certified to ISO 13485:2016 standards. We have an in-house test facility to measure acoustic properties of materials. In addition, ultrasound imaging systems are used to inspect each phantom. Every ultrasound phantom that CIRS distributes has passed thorough testing during manufacture and completion to ensure the highest quality product available. - Page 4 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 5 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 4. Frequency of system assessment: How often each system is evaluated is also up to each facility to determine. 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 pro- gram.

- Page 9 BEAM PROFILE, FOCAL ZONE AND LATERAL RESPONSE WIDTH The beam profile is the shape of the ultrasound beam. A typical beam profile is shown in Figure 1. The narrowest region within the beam profile is indicative of the focal point. By convention, the region surrounding the focal point with intensity within 3 dB of maximum is the focal zone.
- Page 10 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 11 AXIAL AND LATERAL RESOLUTION TESTING (CONTINUED) The Model 040GSE has three combined axial and lateral resolution target groups. The first two groups, at depths of 3 cm and 6.5 cm, are designed for probes of 5 MHz and above. They consist of 13 parallel nylon wires of 80 microns diameter. The third target is located at 10.5 cm depth for evaluation of low frequency probes.

- Page 13 In the second method, the anechoic cylinders are used as simulated focal lesions as follows: Apply coupling gel to the scanning surface or fill the water trough with tap water. Adjust the instrument settings (gain, TGC, output, etc.) as for a “normal” tech- nique.

Page 14: Grayscale Contrast Sensitivity
Testing for low-contrast target detectability is performed as follows: Apply coupling gel to the scanning surface or fill the water trough with tap water. Position the transducer above the cyst of interest and perpendicular to the wires. You should be imaging the circular cross section of the cylinders. Adjust the instrument settings (gain, TGC, output, etc.) as for a “normal”... -
Page 15: Elasticity Contrast Sensitivity
ELASTICITY CONTRAST SENSITIVITY The Model 040GSE provides elasticity targets for the next generation of ultrasound imagers using elastography. The elasticity value for the background is 20 kPa. The target group at a depth of 1.5 cm has a diameter of 6mm, while the target group at 5 cm has a diameter of 8 mm. - Page 16 DEAD ZONE ASSESSMENT CONTINUED The near field group consists of parallel, 100 micron diameter, nylon, monofila- ment wires horizontally spaced 6 mm apart from center to center (Figure 4, page 13). Vertical distance from the center of each wire to the top edge of the scan- ning surface ranges from 5 mm down to 1 mm in 1 mm increments.

- Page 20 ® The Model 040GSE is constructed from a patented, solid elastic material devel- oped at CIRS called Zerdine. Phantoms constructed from Zerdine will not melt or leak when punctured and they do not require refrigeration. Zerdine is also more elastic than other materials and allows more pressure to be applied to the scanning surface without subsequent damage to the material.
