Radiotranslucent foam isolation blocks improve regional tissue accuracy in whole body DXA scans

DXA regional body composition accuracy and precision are critically important in many clinical applications including monitoring lymphedema, performance training, and injury recovery. While total body composition measurements are highly precise, regional measurements exhibit lower precision partly due to inconsistencies in subject positioning. In particular, tissue overlap between body regions (such as breast tissue from the trunk overlying the arms, or hands overlapping the hip) limits the ability to follow regional changes in fat and lean masses, as well as symmetry measures.
