Definitions

  • Radiotherapy equipment refers to a device that uses high-energy electromagnetic radiation (X-radiation, gamma radiation) or particle radiation (electrons, protons, carbon ions) to destroy a diseased tissue, and is widely used in medical treatment in cancer.
  • High radiation doses are produced in a targeted manner in the radiation center of a radiation therapy device, but the problem of radiation targets changing in the body often occurs during the radiation process. If the tumor has grown or has shrunk during the time between planned and actual radiation. Moreover, the center of the lesion area changes according to the progress of the radiation during the treatment.
  • An imaging medium for monitoring treatment proposes an X-ray apparatus and an ultrasonic apparatus. But these devices only provide a limited solution to this problem. Ultrasound imaging lacks penetration depth for many applications. In X-ray imaging, the X-ray sensor may be destroyed or damaged by the gamma rays of the accelerator. In addition, the quality of the organization's shooting often fails to achieve satisfactory results. Therefore, it is currently mainly used to assist the locator and fixture or the label attached to the patient's skin to ensure that the patient is in the same position as the previous radiation plan in the radiation device. The radiation center of the radiation device is thus actually coincident with the radiation target. However, these auxiliary positioners and fixtures are relatively expensive and give the patient an uncomfortable feeling.
