These are the machines that were built in our support laboratories in the Department of Radiology, University of Texas Southwestern Medical Center for various UCR projects. The UCR machine shown below was designed specifically to measure the cortical and cancellous bone pressure wave velocities at the distal head of the ulna.
Machine is scanned over arm and at region of interest through operator control.
An updated version of this device is currently in use. Images of small sized bone samples were generated on this device. The UCR device shown below is used for in vivo studies of humans and animals. When the scan head is filled with water, the rubber membrane bulges out and is coupled to the skin using ultrasound gel. This page last updated May 1997.
