Fig. 4From: Development of a blood sample detector for multi-tracer positron emission tomography using gamma spectroscopya Single rate (SR) detected by the detector as a function of activity concentration (c, red dots) inside the catheter. A linear fit of the measured SR at low c when count rate losses are negligible is also shown (blue dashed line). b Count rate losses (δSR) as a function of activity concentrationBack to article page
