Abstract
A desitometer gantry may translate in two directions for scanning and may swivel about a vertical axis to allow the radiation angle and the detector-to-patient distance to be altered during a scan so as to provide constant magnification of the image and to align the patient's spine with the radiation beam for more accurate edge measurements. A method of reducing the effects of osteophytes on density measurements applies an iterative threshold based on the density difference between hard and soft tissue.
