Abstract

We report on initial results of our new intraoperative probe, capable of functioning in real time with high spatial resolution and high sensitivity. This probe is based on a combination of two novel technologies, an electron multiplying charge coupled device (EMCCD) bonded to a microcolumnar CsI(Tl) scintillator via a flexible fiberoptic. Our data demonstrates that the probe can be used with such beta-emitting radiolabels as ¹⁸F, ¹³¹I, and ³²P. The basic design of the probe and its evaluation using standard clinical phantoms is presented. Also, the operational data obtained on swine models is included to demonstrate the probe´s efficacy in practical procedures.
