The Research of Radiotherapy Treatment Planning System Based on CT Image
Radiotherapy is a very important tumor treatment. And cobalt-60 radiotherapy machine (also known as gamma knife) is a common external beam radiotherapy equipment and is designed mainly for conventional radiotherapy. We develop a software system, which is named Radiotherapy Treatment Planning System, to make gamma knife more precise in radiotherapy. Section Ⅱ introduces the principle of gamma knife the system works with. Section Ⅲ expounds the main components of system. It is composed of image pre-processing, dose computation, dose distribution display, three-dimensional reconstruction, and other modules. Section Ⅲ.B introduces TMR-OAR model the system uses to compute dose distribution. And Section Ⅲ.D introduces the way of human body data and dose data visualization. Finally, Section Ⅲ.E shows the evaluation consequence of a treatment plan. The system works well, and achieves the expected results.
