Embodiment Construction

[0016] Figure 1 figure 2 image 3 As shown, the present invention includes a base 24 installed below the 0 line on the ground, and a collimator base 28, a frame base 29 and a CT machine base 30 are respectively mounted on the base 24 from left to right; among them:

[0017] 1) The collimator library 4 is installed on the collimator base 28, the base 24 and the X-axis slider 25 are relatively slidingly connected by the X-direction guide pair 23; the treatment bed 3 panel and the bed body 27 are opposed by the Y-direction guide pair 21 Sliding connection; the Z-axis slider 26 and the X-axis slider 25 are relatively slidingly connected through the Z-direction guide rail pair 16;

[0018] 2) The radiation device 2 is installed on the upper part of the frame 1 through a bearing seat, the first worm gear 8 and the radiation device 2 are fixed, and the first motor 6 drives the radiation device 2 relative to the frame 1 through the first worm 7 and the first worm gear 8 to achieve B The ...

Abstract

The invention discloses a gamma-rays therapeutic equipment, comprises the foundation fixed under the ground, above the function, the collimator foundation, framework foundation and CT engine base are assembled left-right. The framework can do 200 degree Centigrade axial rotary motion, the irradiation unit can make 200 degrees Centigrade B axial rotating motion. Both the rotating motion are superposed can result in the focal point of the radioactive source rays move on the most of the spherical surface., and realize ''dynamic focal point''. The treatment bed not only can lift fore-and-aft or upper-and-lower, to realize the cross-section or coronal section scan of patients, but also can move left-right, to realize the real-time detection change between gamma-rays treatment and roentgen rays. The real-time detection is good for patients to accomplish one time treatment. The synchronism can make position fixed check and treatment, eliminate the accumulated error of twice position fix, improve the therapeutic precision. This is the so-called ''check on-line''. Increasing the collimator data base, the collimators there changes with the collimators in irradiation unit automatically.

Description

Technical field [0001] The invention relates to a gamma ray treatment device. Background technique [0002] The gamma-ray treatment equipment must include two basic parts: the radiation source radiation device, the bracket for hanging the radiation device, and the treatment bed that carries the patient. The support structure for hanging the radiation device is generally large and cumbersome, and it occupies a large area, and it is fixed on the ground and cannot be moved. The treatment bed must ensure that it can enter and exit the space enclosed by the stent when treating tumors in different parts of the patient. Generally, there is only movement in the forward and backward direction (Y-axis). In the existing static focusing or dynamic focusing gamma-ray treatment equipment, the focus position of the radiation source after the beam is focused is relatively fixed, which is called "static focus". Although the gamma ray of the dynamic focus device can be arced, it can only scan with...
