Outline of Final Research Achievements |
This study aims development of automatic patient positioning software for radiotherapy and further development of a function to quantify and visualize the displacement of separated parts in patient bodies by dividing the images. We developed a “Multi-Volume Matching” technique based on our 2D-3D patient positioning software. In this technique, a 3D-CT volume was divided into multi-volumes such as a volume of interest (VOI) and a base volume (BV). The VOI was segmented so as to include structure whose motion appears in X-ray images. Then, 2D-3D matching was processed using X-ray images and Digitally Reconstructed Radiographs, which were repeatedly generated by changing 3D positions and angles of VOI and BV independently to match most with the X-ray images. Using this technique, we could visualize and quantify the displacement of VOI, as well as bony structure of the base body.
