<p>A digital x-ray bone densitometer for automatically analysing the morphometry of vertebrae (20) from data obtained by lateral digital scans of the bone obtains first and second matrices of data values from X-ray scans. The densitometer (10) includes a C-arm (14) for positioning a radiation source (12) and detector (13) in opposed relationship about a vertebra and for directing radiation along an axis (24) through the vertebra, and for rotating the source detector and axis between first and second angles about said vertebra so that a first matrix of data elements is acquired at the first angle and a second matrix of data elements is acquired at the second angle. The densitometer incorporates a digital computer (18) for receiving and reviewing the matrices of data elements and from them to calculate morphological elements of the vertebra. <IMAGE></p> |
