Design considerations and initial performance of a 1.2cm² beta imaging intra-operative probe

A novel small area beta detector is under development for nuclear emission imaging of surgically exposed radiolabeled tumor beds. The detector size (1.2 cm2) is determined by the requirement to introduce the probe into small cavities, e.g. during neuro-surgical lesion resection, but large enough to produce images of clinical significance. The various components of the imaging chain are optimized by both simulation and measurements.
