Scientists adapt earthquake imaging to peek inside human bones

This completed study tested a new ultrasound technique to detect blood flow inside solid bone, which standard ultrasound cannot see. Nineteen healthy volunteers had ultrasound scans of their forearm and shin bone while blood flow was changed using a blood pressure cuff or by changing body position. The goal was to see if this method, borrowed from earthquake imaging, could reliably measure blood movement inside bone, which may help understand and diagnose bone diseases like osteoporosis in the future.
