Abstract
The two experiments described, one in vivo and the other in vitro, correlate CT (Computerized Tomograph-ic) numbers with mass densities in a cross-sectional scan and CT numbers with the calcium concentration in bones. The in vivo experiment is based on patient scan results and theories used in computerized tomography, specifically the concept of average effective energy (AEE) and the convolution Method in picture reconstruction. The in vitro experiment is based on scans of fresh excised lumbar vertebrae and on the physical analysis (by conventional methods) of the cancellous bone from the vertebrae.
