Embodiment Construction

[0016] As shown in Fig. 1, Fig. 2 and Fig. 3, the present invention includes a base 24 installed below the 0 line on the ground, and a collimator seat 28, a frame seat 29 and a CT frame 30 are respectively installed on the base 24 from left to right; wherein:

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

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

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 therapy device. Background technique [0002] Gamma ray therapy equipment must include two basic parts: the radiation source radiation device, the bracket for suspending the radiation device, and the treatment bed for carrying the patient. The bracket structure for suspending and installing the radiation device is generally large and heavy, occupies a large area, and is fixed on the ground and cannot be moved. The treatment bed should ensure that when treating tumors in different parts of the patient, it can enter and exit the space contained by the bracket, and generally only moves in the front and rear direction (Y axis). In the existing gamma ray therapy equipment with static focus or dynamic focus, the focus position after the radiation source rays are focused is relatively fixed, which is called "static focus". Although the gamma rays of the dynamic focusing device can draw arcs, they can only scan within a l...
