Description
Summary:While effective detection of beta emitters could help localise positron emission tomography (PET) tracer-labelled tumours during surgery, current commercially available heavy and cumbersome surgical probes have imprecise directional capabilities and low { }^{18} \mathrm{~F} beta sensitivity, which overall lack relevance for clinical use. In this work, we explored an innovative approach based on small Compton-angles collimation. With 5 times greater directionality, comparable sensitivity and a significantly smaller probe diameter than basic mechanical collimation, small Compton-angles collimation can enable minimally invasive procedures to improve tumor detection during surgery.
