Multipurpose & Endoscopic Phantom ATS 570
 

The Model 570 Multipurpose & Endoscopic phantom is an easy,
comprehensive means of evaluating imaging systems with an
operating frequency range of 2.25 to 7.5 MHz. The phantom is
designed with 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 gray scale targets ranging in contrast from +6 to -3 dB are
provided to evaluate the system's displayed dynamic range and
gray scale processing performance.

 

The Model 570 offers a new and improved scan surface design to
easily accommodate linear, sector, endoscopic probes and
mechanical sector probes such as used for rectal scanning.
