A portable imaging device currently in development by the

(NSBRI) will produce clear, highly detailed pictures of bone and tissue, helping physicians manage bone health in space and on Earth. The Scanning Confocal Acoustic Diagnostic system, or SCAD, will enable doctors to determine the rate of loss and plan treatment options with the aid of high-quality images, taken noninvasively.

Studies of cosmonauts and astronauts who spent months on space station Mir revealed that space travellers can lose, on average, one-to-two percent of bone mass each month, with the greatest loss in the lower extremities like the femur and hip. The culprit is microgravity, which causes bone loss in critical areas and leaves bones susceptible to fracture upon return to Earth.

Space travellers are not the only demographic concerned with bone loss. According to the National Osteoporosis Foundation, at least 10 million people in the United States suffer from bone loss in the form of osteoporosis.
