| Outline of Final Research Achievements |
In this study, a method for constructing and visualizing three dimensional shape including the movement corresponding to cardiac beat, that is, four dimensional shape of carotid artery from ultrasonic B-mode images for various section on cervix. The developed system enables user to observe the carotid shape from arbitrary viewpoints on computer display by graphical user interface. If viewpoint is set into internal carotid artery, user can observe plaque that is formed inside artery accompanying with arteriosclerosis progress as if he/she goes into artery. The four dimensional visualization facilitates detection a localized region at which the movement is unnatural compared to the surrounding regions on carotid artery. Though such a region is considered to be local lesion, it is very difficult to detect by individual observation of B-mode image for each carotid section. The result of this study is expected to provide us a new generation diagnostic manner for arteriosclerosis.
