Gray-Scale Sensitivity Evaluation

The 84-347 Gray Scale Ultrasound Phantom is a simple tool specially designed to access resolution of masses of varying size, depth, and contrast. It uses proven, patented materials to permit rapid visualization of gray-scale resolution power at continuous depths from 1 to 12 cm, an ideal design for evaluating system-resolving power as a function of depth, size, and contrast. The 84-347 Gray Scale Ultrasound Phantom is usable on all diagnostic ultrasound machines, allowing user evaluation of gray-scale sensitivity with a wide range of transducer frequencies.
