We have developed an intraoperative probe for use in early detection of breast cancer and aiding lumpectomy. The probe consists of a small plastic scintillator, 0.8mm dia and 3mm long, coupled to a single clear optical-fiber strand, and solid state photomultiplier. Due to the small size of the probe, it can be placed inside of a small gauge biopsy needle. The scintillator is very efficient in detecting betas and positrons while being very in efficient to energetic gammas due to small size and low density. High quantum efficiency, 80%, and high gain obtainable, solid state photomultiplier makes the probe very low noise device in detecting beta particles. Intrinsic resolution of the probe is expected to be around 1 mm. Preliminary results using beta sources and a rat bearing R320 adenocarcinoma tumor were very successful.
