Abstract

Through the 4-dimensional RPM coumputerizezd treatment plan the abdomen-liver-cancer patietnt's DVH can be gained Through that according to the absence or presence of Gating the goal is to cure the radiation and through the researching of surrounding tumor tissues and normal tissue dose, the goal is to achieve the cure for radiation. Through the 4-dimensional treatment and the induction treatment and the movement and motion images of the patient, through the process of treatment plan for protecting normal tissue dose rather than anti-tumor dose, a useful treatment plan will be confirmed the research that enhances and improves the accuracy and precision must keep continue to be researched. The RPM will be ran on the part that gets influenced by normal tissues or moving organs. Therefore it will help to develop the process of the treatment of tumor tissues so it is very crucial to reduce the dose of normal tissues to reduce any possible dangers and obstacles.
