Abstract
Small cadmium telluride radionuclide detectors (CdTe) 2-3 mm3 (developed by C. R. N. Strasbourg) have been tested with special reference to their application in biotelemetry. The temperature dependence, geometry characteristics and efficiency of the detectors have been investigated and preliminary in vivo experiments have been performed. The glomerular filtration rate was telemetrically measured by partial body counting of DTPA labeled 99m-Tc. Blood-flow in adipose and muscle tissue was determined by local clearance studies with 133-Xe. In radiocardiographic studies with 99m-Tc, the blood-flow of the heart can be determined. In local clearance and radiographic studies the results obtained with the CdTe-detector were compared with a single NaI(Tl) detector or a γ-camera. The CdTe-detector has been found to fulfil the requirements of a biotelemetric transducerKeywords
