Abstract
The most commonly used imaging instrumentation in nuclear medicine consists of a position sensitive detector (a gamma camera) and a parallel-hole collimator. Such a system has four major sources of blurring: intrinsic detector resolution, spatial distortion, scatter and depth degradation. This gives nuclear images relatively poor spatial resolution when compared to modalities such CT or NMR and limits the utilization of a powerful diagnostic technique. Improvements in instrumentation over the last few years have ameliorated some of these problems. Spatial distortion is no longer a significant problem with digitally corrected cameras; at the same time the improved uniformity makes asymetric high side energy windows practical for scatter reduction. Intrinsic resolution has also improved, but progress beyond the current level will be difficult. However little can be done about the blurring by the collimator of activity at depth.
