The
risk for hypertension and diabetes is correlated closely to the amount of visceral
fat. In this work, the abdominal fat is imaged with a continuously moving
table whole body MRI technique. A method is presented for the repeatable,
general, and reliable differentiation of lipids into subcutaneous and
visceral. The data is restored for intensity uniformity. The corrected image
is processed to segment the body region with the graph cuts algorithm
operating on level sets. Then, the contour separating the subcutaneous and
visceral fat regions is identified with a combination of the random walks
algorithm and graph cuts.
