| Abstract:: |
| Objective To solve part of executive problems by analyzing and editing the control files of brachytherapy. Methods By recording the sources of radioactivity, the time when patients were treated and using the program designed by the C language, the source location and the time treated in this location were tracked to the source urgently. By editing the control files, the follow-up treatment files were produced and then tested with a solid water measuring model. Results For the point A,B defined in the measure model, the deviation between Dose A4 and Dose A1 was 6.12%, the deviation between Dose B4 and Dose B1 was 2.09%. For the planar dose measure in the MapCheck, Plane Dose 4 and Plane Dose 1 rendered as pear-shaped dose distribution,and the dose difference less than 4% reached 93.8%. The point dose and plane dose meeted the clinical standards. Conclusions The follow-up treatment files can complete the part of the unfinished brachytherapy plan exactly and achieve requirements of the dose distribution. |
