Figure 2From: Portable PET probes are a novel tool for intraoperative localization of tumor deposits Portable PET probes detect gamma emission and beta emission from both low and high tested doses of radiation in vitro. Multiple samples of radiolabeled 18F were obtained at two doses (500 μCi and 5000 μCi), Measurements were taken using the portable probes for both gamma and beta emission at the source and at distances up to 5 cm from the source.Back to article page
