In a previous study, the counting efficiency calibration was calculated for 36 computational mesh phantoms called MaMP and FeMP-Male and Female Mesh Phantoms, which span variations in height, weight and gender. They were created to be used in a sitting configuration WBC set-up using an HPGe detector. Now this work is extended to investigate the influence of body sizes and the position of the detector on the counting efficiency (CE) for a different counting geometry. This was done by creating a new set of MaMP and FeMP mesh phantoms lying on a reclining chair and by studying the variation of the counting efficiency using a NaI(Tl) detector for the WBC set-up of SCK-CEN. The deviation of the CE due to the detector's position with respect to the phantom was investigated. Correlations were also studied for CE as a function of trunk volume, waist-hips ratio (WHR) and waist-chest ratio (WCR) for different mesh phantoms.
在之前的一项研究中，针对36个名为MaMP和FeMP - 男性和女性网格体模的计算网格体模计算了计数效率校准，这些体模涵盖了身高、体重和性别的变化。它们被创建用于使用HPGe探测器的坐姿白细胞计数设置。现在，这项工作得到扩展，以研究不同计数几何结构下身体尺寸和探测器位置对计数效率（CE）的影响。这是通过创建一组躺在躺椅上的新MaMP和FeMP网格体模，并使用NaI(Tl)探测器研究SCK - CEN白细胞计数设置的计数效率变化来完成的。研究了由于探测器相对于体模的位置导致的CE偏差。还研究了不同网格体模下CE与躯干体积、腰臀比（WHR）和腰胸比（WCR）的相关性。
