| Outline of Final Research Achievements |
We developed a functional dynamic radiography (fDR) system that provides physiological and functional information of the bone, muscle, and joints using an X-ray flat-panel detector system. For the wrist, sequential radiographs during flexion and extension or rotational movement are considered and movement angles are analyzed.
The fDR allows a great deal of temporal and spatial freedom when imaging. In other words, fDR has a high tolerance for adjusting patient positioning and X-ray projection, which have to be strictly controlled when utilizing static imaging. Thus, we developed a navigation system that incorporates a visual image technique. A real-time video is helpful to instruct the patient to reproduce hand movements. The proposed navigation system reduces incorrect motions and registers errors during dynamic radiography.
We believe that there is a high degree of latent potential for the development of self-imaging and autonomous imaging using radiography navigation systems.
