[0002] Radiotherapy dosimetry is an important part of radiotherapy. It requires mastering the dose distribution characteristics, scattering mode and calculation method of radiation distribution in the human body. It is inevitable to use X-ray irradiation devices. At present, most X-ray irradiation devices are composed of X-ray tubes, high-voltage power supplies and power supplies for lighting filaments. Their large size makes them difficult to control and not suitable for use in teaching or scientific research. At present, there are no X-ray irradiation devices for teaching and scientific research. Most of them are borrowed from clinical X-ray machines for irradiation. Clinical X-ray machines are used for human irradiation and are not suitable for use in teaching or scientific research. During the study, it was found that the blood irradiator has a simple structure and a small size, which meets the basic requirements of teaching and scientific research. However, in teaching and scientific research, in order to study the therapeutic effect of drugs on radiation skin inflammation, such as the therapeutic effect of plant extracts on radiation skin inflammation, it is necessary to irradiate the local or whole body of small animals, and at the same time, it is necessary to study various radiation effects and radiation damage mechanisms. The existing blood irradiator does not have a special device to fix the small animals, nor can it achieve uniform irradiation of the local or whole body of the small animals. Therefore, on the basis of the existing blood irradiator, how to improve it so that it can be used in teaching and scientific research, so that technical personnel in this field can study the therapeutic effect of drugs on radiation skin inflammation, is a difficult problem that needs to be solved urgently.

(4) In the existing X-ray irradiation device, the irradiated object is fixed and can only receive X-ray irradiation at a fixed angle, resulting in uneven dose to the irradiated object.
