Abstract
A method of measuring bone mineral density (BMD) of a selected region of bone in a small body portion (such as a limb or extremity), using a mini C-arm x-ray fluoroscopic imaging system to acquire the data from which the BMD is calculated. Apparatus for performing the method includes a tray for positioning the small body portion in the x-ray beam path of the imaging system and a sample of bone of predetermined density supported by the tray in side-by-side relation to the selected region of bone.
