Eliminating spatial distortions in Anger-type gamma cameras
Here we investigate the position assignment fidelity of gamma-ray Anger cameras (for a more specific description of our setup see
another publication): we show that the major part of deviations is due to systematic distortions, partly caused by the arrangement of the photo-multiplier tubes and partly by non-ideal performances. We present a method to determine these deviations very accurately, and an algorithm to correct the single events for these distortions. We demonstrate the gain in resolution by way of ACPAR measurements of single-crystalline quartz.
