The rubber-based tissue-mimicking material used in the Model 570 has a sound velocity of 1450 m/s when measured at room temperature (22-24°C). The line targets and anechoic target structures have been physically positioned to compensate for the differences in the speed of sound, assuring accuracy of measurements. -

Scan the Model 570 Multipurpose Endoscopic phantom, while adjusting the controls to produce the best possible image. If the bottom of the phantom is visualized, adjust the depth of penetration until only the lower targets are visualized without artifacts produced from the work surface. -

+6 to -3 dB are provided to evaluate the system's displayed dynamic range and gray scale processing performance. The Model 570 offers a new and improved scan surface design to easily accommodate linear, sector, endoscopic probes and mechanical sector probes such as used for rectal scanning. -

Page 7: Vertical Measurement Calibration
The system's dead zone should remain consistent from week to week when using the same instrument settings and Model 570 phantom. Compare the test results obtained from the baseline records. If the current image demonstrates changes in the system's ability to resolve these targets, corrective action should be considered. -
Page 8: Axial - Lateral Resolution
The system's ability to resolve the array targets at given depths should remain consistent from week to week when using the same instrument settings and Model 570 phantom. Compare the test results obtained from the baseline records. If the current image demonstrates changes in the system's ability to resolve these targets, corrective action should be considered. -
Page 9: Sensitivity (Maximum Depth Of Penetration)
The system's focal zone should remain consistent from week to week when using the same instrument settings and Model 570 phantom. Compare the test results obtained from the baseline records. If the current image demonstrates changes in the system's ability to resolve these targets, corrective action should be considered. -
Page 10: Gray Scale & Displayed Dynamic Range
The system's gray scale processing should remain consistent from week to week when using the same instrument settings and Model 570 phantom. Compare the test results obtained from the baseline records. If the current image demonstrates changes in the system's ability to resolve these targets, corrective action should be considered. -
