Abstract: A system for measuring muscle mass of a patient has a dual-energy radiation emission source. A radiation detector is configured to detect radiation emitted from the dual-energy radiation emission source passed through the patient. A processor has a memory with storing instructions, that when executed by the processor, perform a set of operations. The operations include receiving radiation detection data; generating a scan representation; identifying a primary fat target; determining an amount of fat in the primary fat target; comparing the amount of fat in the primary fat target to a reference; and based on the comparison, correcting an estimated amount of lean tissue to generate a corrected muscle mass value.

Abstract: A method includes moving a radiation source and a radiation detector along a scan path substantially transverse to a longitudinal axis of a patient. A beam of radiation is emitted from the radiation source. The beam of radiation is detected at the radiation detector. The detected beam is processed so as to form a first image of a first area of the patient along the scan path.

Abstract: A method of generating a density enhanced model of an object is described. The method includes generating a customized a model of an object using a pre-defined set of models in combination with at least one projection image of the object, where the customized model is formed of a plurality of volume elements including density information. A density map is generated by relating a synthesized projection image of the customized model to an actual projection image of the object. Gains from the density map are back-projected into the customized model to provide a density enhanced customized model of the object. Because the density map is calculated using information from the synthesized projection image in combination with actual projection images of the structure, it has been shown to provide spatial geometry and volumetric density results comparable to those of QCT but with reduced patient exposure, equipment cost and examination time.
