Abstract

A liquid nitrogen cooled CCD TV camera from Astromed, Ltd., has been used for quantitative x-ray medical imaging. The CCD is coupled to a Gd₂O₃(Eu) transparent ceramic scintillator on loan from the Ceramics Division of the General Electric Research Laboratories with an 80 mm f 1.3 oscilloscope camera lens optimized for 2:1 demagnification. High-resolution single-energy x-ray images have been acquired of lead bar patterns, human heel bones, and human teeth. Dual-energy bone-mineral densitometry images have been acquired of the foot and the femur of a rat.
