Research Abstract

The system environment has been created, which can deal with actual clinical CT data using a deformable fusion (registration) software for the respiratory motion evaluation with 4DCT images. A treatment-planning support tool has been also installed to be able to calculate dose distributions for a number of 3DCT images (4DCT image) at one time with an identical treatment plan condition. By use of these tools, accumulated dose distributions could be derived for CT images with different patient positions and/or with respiratory motion and deformation by considering such motion and deformation. Target dose coverage with motion and deformation could be evaluated.
