内容記述 |
We have developed the respiration model to estimate position change of chest skeleton structure by respiration, using 2 chest CT images (learning image) consist of different air-intake volume of same patient. Average distances between real chest skeleton structures and virtual chest skeleton structures obtained by performing respiration simulation using another patient's chest CT images (test image) were 1.43cm at simple expansion model and 0.84cm at proposal respiration model. We have also developed the automatically and rapid chest skeleton structure extraction algorithm and performed same simulation. Using this algorithm, average distances were 1.13cm at simple expansion model and 0.80cm at proposal respiration model on learning image, and 1.57cm at simple expansion model and 0.92cm at proposal respiration model on test image. Average distances between truth feature-points of chest skeleton structure and automatically extracted feature-points (8 feature-points a image) were 1.41cm on learning image and 1.01cm on test image, and required processing times for extracting feature-points were 1.01sec on learning image (512x512x36lpixel) and 1.28sec on test image (512x512x431 pixel). |
