| Outline of Final Research Achievements |
By two ways of following methods, “ The three-dimensional image construction using fluoroscope” was carried out. Both two methods are useful with low exposure dose.
A living body (or model) did one round in front of a fluoroscope. A dynamic radiographic image was recorded. The image reconstruction was done using application. Three-dimensional observation such as maxilla, mandible, maxillary sinus, the cavity of pharynx was enabled. But the image resolusion is low, there is a need to improve.
An X-ray fluoroscopic system with tomosynthesis function was used. The imaging data were reconstructed into 230–240 slices at 1 mm intervals. The tomosynthesis imaging modality delivers a series of tomograms within a single X-ray exposure sequence. In this method, the frontal (lateral) exposure brought front and rear (right and left) tomograms.
