<p>An intraoperative probe system (1) for detecting beta radiation over gamma radiation emitted from a radiopharmaceutical. The probe system has an ion-implanted silicon charged-particle detector (2) for generating an electrical signal in response to received beta particles. A preamplifier (3) located in close proximity to a processing means (4) for amplifying and filtering the electrical signal. A wire (9) couples the probe to a processing means (4) for amplifying and filtering the electrical signal. A counter (6) analyzes the resulting electrical signal to determine the number of beta particles being received by the detector (2). In an alternative embodiment, the wire (9) can be replaced with an infrared transmitter and receiver or a radio transmitter and receiver for "wireless" operation of the probe (1).</p> |
