For several decades now, intraoperative probes have been employed to assist in the detection and removal of tumors. In recent years, intraoperative probes have become an important, well-established clinical tool for the management of cancer, particularly for the detection of sentinel lymph nodes.
Probes for both gamma and beta radiation are now available, as well as small field of view imaging probes. In all cases, the probe is formed of a scintillator coupled to a small photodetector. In the case of the imaging probes, the photosensor is in the form of an array. SiPM sensors are particularly suited to the task of the photodetection due to their compact and rugged nature and their 30V operation. Due to the high detection efficiencies now available with SensL SiPM sensors (>50%), excellent energy resolution is achievable with a variety of scintillators.
This page gives details of recommended products, some related academic papers and some SensL tech notes that may aid a user interested in creating probes using SensL SiPM sensors.
