ABSTRACT:
A dual energy bone densitometer scans the whole body of a patient in successive passes with a narrow fan beam of x-rays and, between passes, moves the patient table along multiple axes and rotates the C-arm about a rotation axis spaced from the focal spot. The coordinated multi-axes motion of the table and C-arm helps in piecing together the x-ray data from different passes and helps reduce the footprint of the instrument.
