Jaszczak PET/SPECT Phantom

• System performance valuation of: Collimator, Artifacts, Calibrator, and Reconstruction Parameters
• Acceptance testing
• Routine quality, assurance and control
• Evaluation of center-of-rotation error
• Evaluation of non-uniformity artifact
• Evaluation of changes of radius-of-rotation on spatial resolution
• Evaluation of reconstruction filters on spatial resolution
• Evaluation of attenuation and scatter compensation
• Single slice volume sensitivity
• Total system volume sensitivity
• Lesion detectability

The Jaszczak SPECT Phantom provides consistent performance information for any SPECT or PET system. Multiple performance characteristics of camera-based SPECT systems are evaluated from a single scan of the phantom. On-axis and off-axis transverse line spread function may be easily measured without removing the cover plate. Measurements of full-width-half (or tenth) maximum can be readily determined, either in air or in water.
