A method for lateral localization of a compact gamma source in radionuclide diagnostics
Abstract
A method for lateral localization of a gamma source in a medium with a miniature single channel scintillation detector is developed and experimentally tested. Method is based on simultaneous registration of two (or more) gamma lines emitted from an area of increased uptake of a radiopharmaceutical in the patients body. The proposed method is tested with the most widely used medical radioisotope technetium-99m which has a 140 keV gamma emission line and a 18 keV characteristic x-ray line. The results of experimental studies show that the lateral coordinate of a point-like 99mTc source can be determined with an accuracy of ± 4 mm at the depth of soft tissues equivalent phantom up to 30 mm.
