| Research Abstract |
Dual energy radiography technique is known for obtaining quantitative images of bone and soft tissue. One method is to use two different tube voltages with a flat-panel detector (FPD), and the other method is to use a sandwich detector comprised of two computed radiography (CR) plates with an inter-plate filter. The two-exposure method has far better signal-to-noise ratio, but is subject to some slight motion misregistration, and requires higher radiation doses. We have developed a new single exposure quantitative imaging technique using Microsoft Kinect which can measure 3D shape of the object. By using this method, it was possible to obtain the bone and soft tissue images of a 2-component phantom.
