Page 5: Section 1. Introduction
Product Description The Model 549 General & Small Parts Phantom is an easy, comprehensive means of evaluating imaging systems with an operating frequency range of 2.25 to 15.0 MHz. The first 6 cm of this model has been designed to accommodate the higher frequencies, whereas the area between 6- 30 cm is reserved for frequencies less than 7.5 MHz. -
Page 6: Tests Performed
Tests Performed The following tests are performed: • Dead Zone or Ring-Down • Vertical Measurement Calibration • Horizontal Measurement Calibration • Focal Zone • Sensitivity/Penetration • Axial & Lateral Resolution • Functional Resolution • Image Uniformity • Gray Scale & Displayed Dynamic Range Introduction Page 2... -
Page 7: Section 2. Setup
Scan the Model 549 General & Small Parts 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. -
Page 8: Section 3. Testing Procedures
The system’s dead zone should remain consistent from week to week when using the same instrument settings and the Model 549 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: Vertical Measurement Calibration
The system’s vertical distances measurements should remain consistent from week to week when using the same instrument settings and the Model 549 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: Horizontal Measurement Calibration
The system’s horizontal distance measurements should remain consistent from week to week when using the same instrument settings and the Model 549 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 11: Axial And Lateral Resolution
Testing Procedure Model 549 provides three scanning surfaces to evaluate axial-lateral resolution at nine given depths. Target locations in the phantom are referenced from the first axial target. The line targets are spaced at 4.0, 3.0, 2.0, 1.0, and 0.05 mm intervals both axially and laterally. -
Page 12: Results
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 the Model 549 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 13: Results
The system’s focal zone should remain consistent from week to week when using the same instrument settings and the Model 549 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. -

The system’s depth of penetration should remain consistent from week to week when using the same instrument settings and the Model 549 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 15: Testing Procedure
The system’s functional resolution and image uniformity should remain consistent from week to week when using the same instrument settings and the Model 549 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, or major areas of image nonuniformity are observed,... -

Page 17: Section 4. Support And Maintenance
Repair The phantoms and the parts provided with the phantoms cannot be repaired by the user. If there are problems with any of the devices, contact Sun Nuclear Support. Cleaning For best results, the phantom should be kept clean at all times. In particular, a buildup of dried coupling gel on the scan surface should be avoided. -
