Abstract:
At the Lawrence Livermore National Laboratory, we are developing a system that will more accurately measure fat, muscle, and bone content from ultrasonic images of the chest wall. This paper describes a procedure that will allow chest-wall thickness to be determined to within +/- 1.5 mm (compared with the +/- 3-6 mm from current techniques) and may allow absolute errors in chest-wall composition to be reduced to +/- 4%.
