Abstract
<p>Radiotherapy planning requires calculation of cumulative dose distribution of a series of treatment planning. In the treatment of the uterus, a radioactive tool is inserted into the uterus which causes the uterus to deform. We aimed at developing deformable image registration to support treatment planning considering a physical constraint of the uterus by the tool. Intensity-based deformable image registration has been intensively studied. However, the physical constraint by the tool could not be considered. In this study, we applied a finite element method to intensity-based image registration to consider physical characteristics. The center lines are extracted from the uterus and radioactive tool automatically. The experimental results using a phantom and patients' data revealed that the proposed method is relatively effective when the uterus deforms largely.</p>
