Dual-core Steered Non-rigid Registration for Multi-modal Images via Bi-directional Image Synthesis

Prostate cancer (Partin, Yoo et al. 1993, Shen, Lao et al. 2004) is a common type of cancer among men worldwide. Clinically, external beam radiation therapy (EBRT) is one of the most efficient ways for treating prostate cancer. In EBRT (de Crevoisier, Tucker et al. 2005), Computed Tomography (CT) is of great importance as it provides Hounsfield unit (HU) values, which can be used for dose planning purpose. In the planning stage of EBRT, in order to deliver prescribed dose to the prostate volume, while spare nearby normal organs from the harmful radiation, three critical pelvic organs, i.e., prostate, bladder and rectum, need to be contoured precisely.
