Estimating the term…
An intraoperative imaging system combines a gamma probe and an ultrasound probe. The probes are linked to provide co-registration of gamma radiation detected by the gamma probe with an image acquired by the ultrasound probe. The gamma probe has a converging collimator made of a metal block having a plurality of channels therein, which converge from an output face toward an input face. Each channel extends between and opens out at the faces such that openings at the input face have smaller cross-sectional areas than openings at the output face so that each channel tapers inwardly from the output face to the input face. The collimator has an external focal point distant from the input face. The system improves identification and localization of cancerous cells, facilitating more accurate biopsy data and more complete surgical resection. The gamma probe increases sensitivity, while maintaining spatial resolution, and increasing depth of view.
