The validity of the gamma mass scanner in predicting center of mass and moment of inertia of biological tissue was tested using legs of lamb. The reaction board, immersion and pendulum methods were used to obtain one or both the center of mass and moment of inertia of the legs. The results from these methods were compared with those obtained from the scanner. Results indicated that the gamma mass scanner consistently predicted the mass of the legs to within a 1% error, the center of gravity within 2.1% and moment of inertia to within 4.8%. Within the limits of this investigation it was concluded that the gamma mass scanner shows promise as a valid and exact method for determining the center of gravity and moment of inertia of biological tissue.
使用羊腿测试了伽马质量扫描仪在预测生物组织质心和转动惯量方面的有效性。采用反应板法、浸没法和摆锤法来获取羊腿的质心和转动惯量中的一个或两者。将这些方法得到的结果与扫描仪得到的结果进行比较。结果表明，伽马质量扫描仪始终能将羊腿质量预测在1%的误差范围内，重心预测在2.1%以内，转动惯量预测在4.8%以内。在本研究的范围内得出结论，伽马质量扫描仪有望成为一种确定生物组织重心和转动惯量的有效且精确的方法。
