The Lunar PRODIGY Advance is a GE healthcare DEXA system which can be used for whole body scans. GE healthcare DEXA systems uses a K-edge filter that absorbs the X-rays in the middle energy range creating two low energy X-rays and classes the Lunar iDEXA as a narrow-angle fan beam. It measures the attenuation of the two X-rays as they pass through body tissues. Different tissues absorb these x rays in different manners and it therefore distinguishes bone mass from soft tissue and within the soft tissue fat mass and lean mass. The manufactures enCORE software provide estimates of fat, bone mineral content and lean mass in the total body and in specifically defined regions. The enCORE corescan software feature can produce estimates of visceral adipose tissue (mass and volume) within the android region. The measurement field is 197.5 cm x 60 cm for whole body scans with a maximum patient weight 159 kg and a exposure of 0.4 - 0.8 µGy.
