Gray Scale Ultrasound Phantom ATS 531
The Model 531 Gray Scale phantom is designed to evaluate an imaging system’s gray scale processing and displayed dynamic range. The phantom contains 10 levels of contrast
target structures relative to the background, ranging from -15 dB to +15 dB. The phantom is constructed of a rubber-based tissue mimicking material. It is contained within
two protective outer walls to provide strength and permanence.
The acoustic properties of all biologic and non-biologic materials are affected by temperature variations. Most diagnostic imaging systems and tissue-mimicking phantoms
are calibrated at room temperature, commonly referred to as 23°C. To ensure measurement accuracy ATS incorporates a thermometer strip affixed to the outside surface of the phantom.
