Scan Plane Thickness Phantom
Scan Plane Thickness Phantom
The Scan Plane Thickness Phantom provides a quick, easy and accurate way of determining ultrasound slice thickness. This phantom has a diffuse, sound-scattering plane adjusted at a 45 angle to the ultrasound beam. Filled with tissue mimicking gel, sound transmits easily through the composite film top to the interior of the phantom. When positioned in the plane of the transducer slice, the sound scattering plane is imaged as a line 45 degrees from horizontal. The horizontal thickness of the imaged line indicates the in-plane transducer beam width at various image depths. When positioned across the plane of the transducer slice, the sound scattering plane images as a horizontal line. The vertical thickness of the imaged line indicates the slice thickness at the image depth of the line. An optional foam-lined carrying case is available with the Gammex 421 phantom.
