Abstract
Objective:To investigate the application of the image-guided technique in abdominal-pelvic intensity-modulated radiotherapy.Methods:For the pelvic-abdominal tumor patients in abdominal-pelvic intensity-modulated radiotherapy with negativep ressure vacuum bag immobilization,using accelerator conebeam CT,to get three-dimensional images of the target for the first three times before radiotherapy,and to get two images position errors,and to correct after confirming the errors.Repeat once a week.Data was processed using SAS statistical software system.Results:The patients of abdominal-pelvic tumors with negative pressure vacuum mobilization needed image-guided correction; the image guiding verification showed that head-foot direction error was (-0.71 ±1.83)mm,front and rear direction was (0.21 ± 1.71)mm,the left and right direction was (0.14± 1.34)mm.Conclusion:The image-guided technology is conducive to improve positioning precision in the abdominal-pelvic intensity-modulated radiotherapy with the vacuum bag fixed,and reduce the position errors and direct the following fractionated radiotherapy positioning.关键词
