Abstract

An embodiment in accordance with the present invention provides a device and method for a quantitatively calibrated computed tomography scanner. The device includes a gantry configured for receiving a patient or part of a patient. The gantry includes an X-ray source and a detector positioned opposite said X-ray source, such that said detector receives the X-rays emitted from the X-ray source. Calibration phantoms are integrated with the gantry and / or a device within the scanner so as to allow for calibration in quantitative CT measurements of Hounsfield units and / or bone mineral density.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application No. 61 / 656,775, filed June 7, 2012, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates generally to medical imaging. More specifically, the present invention relates to a device for determining bone mineral density in Computed Tomography (CT). Background technique [0004] Diagnosis and treatment of a range of musculoskeletal disorders is expected to benefit from high-quality accurate imaging and morphological assessment as provided by peripheral quantitative CT (pQCT). For example, osteoporosis presents a growing health burden involving loss of bone density leading to fragility fractures. Similarly, osteoarthritis (OA), especially in the aging and obese population, is an increasingly prevalent degenerative joint disease characterized by biomechanical stress and consequent loss of ca...
