Tumor motion and the control methods in precision radiotherapy / 国际肿瘤学杂志

ABSTRACT

Tumor motion can reduce the dose to the target volume while give unnecessary irradiation to the surrounding normal tissues and is an important factor to influence the precision radiotherapy. Many resear-ches find tumor motion exist in the radiotherapy for many tumors in thoracic and abdominal. Its main reason is respiration movement. Nowadays, there are some measurements to control it. The precision of radiotherapy can got further improved through the appropriate control to minimize the disadvantages influence of tumor motion in the precision radiotherapy.
