Paper Abstract

A probe system has been designed for the accurate location of areas of increased radionuclide uptake. Different type of applications are possible i.e. when precise position or even identification of the radionuclide is needed, like in wound investigation. In this paper, we restrict ourself to a system incorporating two probes, for the identification of `hot' lymph nodes, close to the surface of the body. Axillary lymph node involvement is a major prognostic indicator and treatment planning factor in both melanoma and breast cancer. However, sentinel node localization is relatively difficult often due to close proximity of the primary tumor. The developed instrument has a very sensitive detector, with good spatial resolution, able to discriminate between primary and scattered radiations.
