The Model 549 General & Small Parts phantom combines a 30cm depth of field needed to test lower-frequency imaging probes (2-7.5 MHz) with small features in the first 6 cm to test small parts probes (7.5-20 MHz).The scanning wells when filled with water provide an ideal means to evaluate endoscopic probes. Simply lie the active area of the transducer onto the surface of the phantom. The procedure is the same as for any standard linear transducer.
The Model 549 is designed with a combination of monofilament line targets for distance measurements and tissue mimicking target structures of varying sizes and contrasts. One hundred and twenty (120) cystic-like tar- get structures are positioned in-line vertically, thereby permitting an entire target group to be displayed in one view. Due to the acoustic similarity of the background material and the target structures, artifacts caused by distortion, shadowing or enhancement have been eliminated.
Six gray scale targets ranging in contrast from +15 to -15 dB are provided to evaluate the system’s displayed dynamic range and gray scale processing performance.
All ATS urethane phantoms are guaranteed for the useful life of the phantom, defined as 10 years.
