Recent years, the number of radiotherapy patients is increasing. Meanwhile, in recent complicated radiotherapy, verification of the dose calculated value is also important from the aspect of quality assurance. Also, it known that the radiation sensitivity of the human body is different for each organ, and it is desirable to accurately measure the exposure dose of each organ having a complicated shape in terms of verifying side effects of treatment. The purpose of this study is to integrate X-ray CT and photochromic material technologies and tailoring the radiation dosimeter for each patient using 3D printers.
