Rectal Scan Ultrasound Phantom ATS 540

Model 540 is a rubber based tissue-mimicking rectal scan phantom. It is suited primarily for performance testing of rotary-type transducers, resulting in a displayed image of a full 360°. The phantom may also be used to evaluate the performance of bi-planar and end-fired transducers. Model 540 is contained in a protective housing. An internal scan well permits insertion of the transducer directly into the body of the phantom, thereby mimicking the application. The phantom contains five groups of cystic-like targets of varying sizes and depths, and five levels of gray scale. The target structures are arranged in a radial pattern from the center of the scan well.
