Multipurpose & Endoscopic Phantom (Model ATS 570) – CIRS

Any questions or would you like to order this product? Do not hesitate to contact us

The Multipurpose and Endoscopic Phantom (Model ATS 570) is an easy, comprehensive means of evaluating imaging systems over the full range of clinical imaging frequencies (2 MHz to 18 MHz).

The phantom has a combination of monofilament line targets for distance measurements and tissue mimicking target structures of varying sizes and contrasts. Due to the acoustic similarity of the background material and the target structures, artifacts caused by distortion, shadowing and enhancement have been eliminated

Four grey scale targets ranging in contrast from +6 to -3 dB evaluate the system’s displayed dynamic range and grey scale processing performance. This model offers a new and improved scan surface design for easily accommodated endoscopic probes and mechanical sector probes.
