The gamma mass scanning technique for inertial anthropometric measurement

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.
