COMPACT C-ARM TOMOGRAPHIC BONE SCANNING SYSTEM

摘要

The invention relates to methods of using a bone densitometer to scan bone, notably vertebrae. The bone is scanned while maintaining the X-ray source (44) and detector (50) at a first angle, and a two dimensional array (78) of pixels (76) is obtained. This is analysed electronically and used to adjust the position of the detector (50) relative to the patient during a second scan at a different angle. Electronic analysis of the data is used to eliminate the effect of osteophytes on the bone density image.
