Abstract:
Objective To investigate the clinical value of vacuum pad and body film fixation in radiotherapy for thoracic and abdominal tumors. Methods A total of 240 patients with thoracic and abdominal tumors who were treated with radiotherapy were randomly selected and divided into group A (simple vacuum pad fixation,60 patients),group B(simple body film fixation with unimproved solid plate, 60 patients),and group C(vacuum pad and body film fixation with improved solid plate,120 patients).The difference between groups were analyzed with single variance analysis method. Results The setup error was small in group C and large in groups A and B. There were significant differences in the setup error between the three fixation methods(P=0.000). Conclusions A combination of vacuum pad and body film fixation is better than vacuum pad or body film fixation in radiotherapy for thoracic and abdominal tumors. The combination method has many benefits, including simple and convenient operation, comfortable and repeatable body fixation,reduced artificial errors,and improved positioning precision.
