Jaszczak Phantoms Flanged • SPECT
ECT Phantom for SPECT
Please measure your image receptor to be certain of the dimensions
of your image receptor.
The Jaszczak SPECT Phantom provides consistent performance information for any SPECT 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.
The Phantom is used for:- ECT phantoms with protruding flanged top and with 3.2 mm cylinder wall thickness
- System performance valuation of:
- Collimator, Artifacts, Calibration, 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
SPECT Phantoms are available in two models. The Deluxe Phantom is used for high resolution cameras. The Standard Phantom is used for lower resolution cameras.
