AI Technical Summary

Problems solved by technology

The above operations not only increase the time of radiotherapy and the difficulty of positioning the patient, but also usually cause the center of the tumor to deviate from the center of the system due to the limited movement distance of the treatment bed, which cannot ensure that the radiation dose of each part is consistent. As a result, the dose of radiotherapy for tumors blocked by normal human tissues is insufficient, so that effective therapeutic effects cannot be achieved

Abstract

The invention provides an accelerator adjusting device. The adjusting device comprises a machine head bearing frame, a machine head lifting adjusting device and a deflection bracket. The accelerator adjusting device can respectively adjust the up and down height of a machine head and left and right deflection displacement, and solves the problems that the tumor and the entire rotary treatment center of equipment are in non-concentricity caused by structure limitation of image radiography equipment. Besides, when normal human body tissue can be used for shielding tumors, radioactive source deflection can be performed to prevent illumination on normal human body tissue, the radiation treatment time of patients can be shortened, and the radiotherapy effect is increased. The accelerator adjusting device is used for radiotherapy equipment introduced by the image radiography equipment, and is used for solving the problems that a conventional product can only perform single dimensionality radiation treatment.

Description

technical field [0001] The present invention relates to the technical field of radiotherapy equipment guided by image contrast equipment, in particular to an accelerator adjustment device. Background technique [0002] Malignant tumor is one of the main threats to human health, and it is showing an increasing trend year by year. Radiation therapy treats tumors by irradiating high-energy radiation. Because high-energy rays can not only kill tumor cells, but also cause damage to normal tissue cells, precision is a key factor in radiotherapy techniques. [0003] At present, in the research work of radiotherapy systems at home and abroad, the radioactive source head can only rotate around the hospital bed to perform single-dimensional radiotherapy on the patient's tumor site. For example, the MRIdian of ViewRay Company in the United States installs three Co60 remote treatment heads through a rotating frame to realize tumor positioning and treatment. The CCI (Cross Cancer Inst...
