MECHANISM

Radiotherapy is to kill tumor cells with high-energy particles and rays, such as X-rays or y-rays, so as to treat tumors. The BOLUS is placed on the body surface to improve the dose distribution of energy and radiation and significantly increase the skin surface dose. Meet the requirements of clinical dose treatment, so as to improve the treatment effect of local lesions.
