ABSTRACT:
An intraoperative system made be used for preferentially detecting beta radiation over gamma radiation emitted from a radiopharmaceutical. The system has ion-implanted silicon charged-particle detectors for generating signals in response to received beta particles. A preamplifier may be located in proximity to the detector filters and amplifies the signal. Also, a wire may be used to couple the probe to a processing unit for amplifying and filtering the signal.
