| Abstract: | Recently, 192Ir high dose rate(HDR) afterloading are widely used in brachytherapy. The advantage of using HDR systems over low dose rate systems are shorter treatment time and higher fraction dose. To guarantee the veracity of the delivery dose, several quality control methods are described in this work. With these we can improve the position precision, time precision and dose precision of the brachytherapy. |
