|Gray Scale Ultrasound Phantom.|
EVALUATE RESOLVING POWER AS A FUNCTION OF DEPTH, SIZE, AND CONTRASTThe CIRS Gray Scale Ultrasound Phantom is a single, simple tool to assess resolution of masses varying in size, depth and contrast. The phantom's unique design allows for rapid visualization of gray scale resolution power at continuous depths from 1 to 12 cm.
Due to the controlled scatter characteristics of the targets, the Model 047 may be used to evaluate gray scale sensitivity on all diagnostic ultrasound machines with a wide range of transducer frequencies. This phantom is an ideal training tool for learning optimum system setup and evaluating system performance.
Masses may be viewed with either a circular or elliptical cross-section. The mass diameters were selected so the volume imaged would double as the diameter increased. The gray-scale levels were selected to achieve a doubling in signal intensity as you move from mass to mass. The anechoic masses comply with the ACR accreditation program.
The phantom is constructed of Zerdine(1), a patented, tissue-mimicking material and is housed in a rugged ABS plastic for increased durability. The Gray Scale Ultrasound Phantom includes foam-lined carry case, certificate of compliance, user guide and 48-month warranty.
