The conventional radioisotope scanner has been used as a whole body counter. The background index of the system is 10.9 counts per minute per ml of sodium iodide crystal. The sensitivity and derived sensitivity parameters have been evaluated and found to be suitable for clinical studies. The optimum parameters for a single detector at two positions above the lying subject have been obtained. It has been found that for the case of 131I measurement it is possible to assay a source located at any point in the body with coefficient of variation less than 5%. To add to the versatility, a fixed geometry for in-vitro counting of large samples has been obtained. The retention values obtained by the whole body counter have been found to correlate with those obtained by in-vitro assay of urine and stool after intravenous administration of 51Cr-albumin.
传统的放射性同位素扫描仪已被用作全身计数器。该系统的本底指标为每毫升碘化钠晶体每分钟10.9次计数。已对灵敏度和导出的灵敏度参数进行了评估，发现它们适用于临床研究。已获得在仰卧受试者上方两个位置处单个探测器的最佳参数。已发现，对于¹³¹I测量的情况，可以对位于体内任何点的源进行分析，变异系数小于5%。为增加其通用性，已获得用于大样本体外计数的固定几何结构。已发现全身计数器获得的潴留值与静脉注射⁵¹Cr-白蛋白后尿液和粪便的体外分析获得的潴留值相关。
