VARIABLE COMPOSITION PHANTOM SIMULATING VARYING DEGREES OF BODY FAT FOR DUAL ENERGY X-RAY MACHINE CALIBRATION

Disclosed herein is a phantom for calibrating dual energy x-ray equipment for body fat measurements. In particular, the present invention provides a limited number of calibrated plates of materials simulating different body fat percentages. By combining the plates, a range of simulated body fat compositions may be precisely obtained. The plates may be of arbitrary size to provide a simulation over a broad area and may include a high density end cap for triggering an automatic region of interest detection for certain scanner systems.
