Fig. 5From: Evaluation of two intraoperative gamma detectors for assessment of 177Lu activity concentration in vivoThe organ thickness dependence of the two detectors. The count rate was determined for homogeneously distributed 177Lu in agarose gel with a thickness of 10–148 mm. Both detectors showed saturation at about 110 mm. The star indicates the largest thickness where a statistically significant difference was found compared with the signal intensity at 148 mmBack to article page
