Abstract:
1. A method comprising: acquiring x-ray measurements using a dual-energy x-ray absorptiometry (DXA) system for respective pixel positions related to a two-dimensional projection image of a portion of a subject's abdomen, wherein at least some of the measurements are dual-energy x-ray measurements; placing a plurality of regions of the image in which the image is obtained using the DXA system, wherein said placing includes placing a first region of the image which extends from a first side of the abdomen to a second side of the abdomen, and placing a second region which extends across an inner abdominal cavity from the first side to the second side between innermost extents of an abdominal muscle wall, and wherein said placing of said second region of the image includes identifying a left and a right innermost extent of abdominal muscle wall by identifying inflection of adipose tissue values; computer processing to combine the plurality of regions to provide an estimate of visceral fat (VAT) in which said estimate of visceral fat is distinguishable from subcutaneous fat (SAT), wherein said computer processing includes computer processing at least some of the x-ray measurements for placing the second region of the image; and providing and displaying selected results related to said estimate of visceral fat in which said selected results of visceral fat is distinguishable from subcutaneous fat.
