Using a gamma photon absorptiometric technique, a time-effect curve was constructed for the bed rest state. Further studies are required and should lead to a confirmation of the interest of these absorptiometric indexes. absorptiometry noun ... The commoner forms of these devices in Europe and North America include heel and forearm dual energy x ray absorptiometry and quantitative ultrasound at the heel. Bone mineral density of the lumbar spine and proximal femur were measured with dual energy x ray absorptiometry (QDR 1000, Hologic Inc, Waltham, Massachusetts).
