ABSTRACT:
An intraoperative probe system for preferentially detecting beta radiation over gamma radiation emitted from a radiopharmaceutical is described. In one embodiment, the probe system of the present invention is a probe having an ion-implanted silicon charged-particle detector for generating an electrical signal in response to received beta particles. In such an embodiment, a preamplifier may be located in close proximity to the detector filters and amplifies the electrical signal. Furthermore, a wire may be used to couple the probe to a processing unit for amplifying and filtering the electrical signal, and a counter may be utilized to analyze the resulting electrical signal to determine the number of beta particles being received by the detector. Alternatively, the wire can be replaced with an infrared or radio transmitter and receiver for wireless operation of the probe.
