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 dual-energy X-ray absorptiometry (“DXA”) system includes an x-ray source assembly comprising a source carriage to move the x-ray source assembly along a scan path, the scan path comprising an active scan portion and a reference measurement portion. A detector assembly including a detector carriage to move the detector assembly with the source assembly and to collect scan data at active scan portions. A support structure supporting the source and detector assemblies. A calibration controller coupled a calibration element having a known x-ray attenuation value and configured position the calibration element between the source and detector assemblies during the reference measurement portion and to remove the calibration element from between the source and detector assemblies during the active scan portion. A processing unit operable to compare the reference measurement against an expected reference value to identify a variance and to selectively trigger an action in response to the variance.
