However, when the micro-beam X-ray therapy equipment is established by using an ordinary X-ray light source, if the above-mentioned multi-slit collimator is still used to obtain the micro-beam X-ray series, then the X-ray power density at the obtained X-ray micro-beam is unit The X-ray intensity on the area will be very low, so it cannot meet the requirements of micro-beam X-ray therapy

Embodiment Construction
[0025] The basic idea of the present invention is to establish a multi-capillary X-ray beamforming system through a certain number of single-channel glass capillaries (single-capillary for short). A series of X-ray microbeams with high power density, thus resulting in the microbeam X-ray therapy spectrometer of the present invention.
[0026] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0027] see figure 1 , shows a micro-beam X-ray therapy spectrometer, the micro-beam X-ray therapy spectrometer includes: an X-ray light source 1 and a polycapillary X-ray beam focusing system 2 . in:
[0028] The X-ray light source 1 is an ordinary X-ray light source in the laboratory, and its power range is 0.5kW-20kW. The X-ray light source 1 is located at the entrance end of the multi-capill...

The invention discloses a micro-beam X-ray treatment spectrometer, which comprises a X-ray light source and a multi-capillary X-ray bunching system, wherein the X-ray light source is positioned at an inlet end of the multi-capillary X-ray bunching system; the multi-capillary X-ray bunching system is formed by arranging a plurality of single-channel glass capillary tubes; the inlet end of the multi-capillary X-ray bunching system receives X rays emitted by the X-ray light source, and the converged X rays are emitted from an outlet end to form a X-ray microbeam series. The invention also discloses a multi-capillary X-ray bunching system and a multi-capillary X-ray bunching method. The system comprises 350 to 500 single-channel glass capillary tubes. Therefore, the X-ray microbeams meeting the requirement can be acquired by the ordinary X-ray light source without adding a low-energy X-ray filter additionally, so that the micro-beam X-ray treatment spectrometer has a compact structure and is convenient to use.
Description
technical field [0001] The invention relates to the technical field of X-ray therapy, in particular to a micro-beam X-ray therapeutic spectrometer based on a polycapillary X-ray beamforming system, a polycapillary X-ray beamforming system and a method. Background technique [0002] At present, X-rays are widely used in tumor treatment, but when using millimeter-scale X-ray beams to treat tumors, the skin immunity effect will be destroyed. In order not to destroy the skin immunity effect, people use micro-beam X-rays to treat tumors, because the damage of micro-beam X-rays to non-focused areas can be repaired through cell regeneration, so the skin immunity effect will not be destroyed. [0003] Among X-ray sources, synchrotron radiation X-ray sources can provide high-intensity X-rays. Moreover, with the maturity of synchrotron radiation technology, micro-beam X-ray therapy equipment based on synchrotron radiation sources has begun to be established. When using synchrotron r...
