What should the intrinsic uniformity percentage be for a SPECT gamma camera?

The intrinsic uniformity percentage for a SPECT gamma camera is an important quality control measure that assesses how evenly the camera responds to gamma radiation across its entire field of view without any influence from external factors. A value within the range of 2 to 3% indicates that the camera maintains a relatively uniform response when activated, which is crucial for accurate imaging and diagnosis.

If the intrinsic uniformity falls within this range, it signifies that the camera is functioning well, producing consistent and reliable images across the scan area, thereby ensuring that variations in image quality do not adversely affect interpretation and patient outcomes. Values higher than this could signal issues with the camera's performance, such as problems with the detector or calibrations that may need to be addressed to maintain accuracy in imaging.

This standard is part of routine quality control protocols employed to ensure optimal performance of SPECT gamma cameras, which are pivotal in various diagnostic procedures.
