| 内容記述 | To allow tumor targeting in the context of liver treatment planning, it is important to estimate the tumor position dynamically. In fluoroscopy, a multiple template-based method has been proposed for tumor tracking without fiducial markers. This method requires ground-truth tumor positions on training images to estimate tumor templates; however, these positions have to be manually set. Moreover, the low contrast of fluoroscopy images makes tumor position marking difficult. To solve this problem, we propose a semiautomatic tumor position tracking method for the training images to reduce both the positional error arising from the manual setup as well as the time required by setting the ground-truth manually. | |||||
