Intraoperative nuclear imaging probe

Novel radiopharmaceuticals have recently generated a resurgence of interest in the use of hand-held, intraoperative nuclear probes to provide in vivo localization of tumors. A hand-held intraoperative nuclear imaging probe is being developed based on a position-sensitive photomultiplier tube. A compact bench-top prototype system has been built which is capable of providing real-time images with 2.5-mm resolution (for /sup 99m/Tc) over a 7-cm-diameter active area. The design and measured performance of the prototype are discussed.<
