The development of high resolution PET systems is important for the wider application of this techniques. The resolution of PET is limited by a number of physical factors such as positron range, small angle deviation, and sampling frequency. The design of the detector array and its sensitivity remain critical factors; designs incorporating analog coding have proven to be useful. PCR‐I, a single plane PET system, has demonstrated the concept and has produced useful images in animal studies. PCR‐II will extend the concept to a two dimensional detector array resulting in a system with high resolution and high sensitivity.
