TWO-DETECTOR ANALYZER OF ARTERIAL BLOOD RADIATION LEVEL FOR PET STUDIES

摘要

FIELD: medical equipment.;SUBSTANCE: invention relates to the field of medical technology. The two-detector arterial blood radiation level analyzer for PET studies contains a capillary catheter for blood sampling, a perfusion pump connected to it and an automatic arterial blood radiation level detector with a high time resolution and a low signal-to-noise ratio, while a second well-type detector with a low time resolution and a high signal-to-noise ratio is installed at the output of the automatic arterial blood radiation level detector, passed through the first detector during the entire time of the procedure. ;EFFECT: increase in the quality of the received signal, an increase in the accuracy of measuring blood activity while reducing the invasiveness of the procedure, and a decrease in the probability of capillary blockage. ;1 cl, 1 dwg
