 | Gray Scale Ultrasound Phantom. |  |
 | 
Introducing a new design using proven, patented materials to permit rapid visualization of gray scale resolution power
at continuous depths from 1 to 12 cm. The Model 047 is a single simple tool to assess resolution of masses varying in
size, depth and contrast. This model is usable on all diagnostic ultrasound machines thus allowing user evaluation of
gray scale sensitivity 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. Dimensions:
13.8" X 5.1" X 6.7" (35cm X 13cm X 17cm) Weight: 23lbs (10.4kg) Scanning well: 1cm deep Material:
Zerdine® 1 solid elastic water-based polymer Freezing Point: 0°C, Melting Point: Above 100°C Scanning Membrane: Saran-based laminate. |
