Problems solved by technology

If stereotactic therapy is required, it is necessary to add a stereotactic isocentric device (commonly known as X-knife) to the medical linear accelerator or use a special stereotactic radiotherapy device, such as the γ-knife, but the latter cannot perform conformal intensity-modulated therapy
Such equipment requires a large investment and is complicated to operate and use.

Embodiment Construction

[0013] according to Figure 1-Figure 3 As shown, the radiation source carrier 7 is equipped with gears, the radiation collimator 8 is equipped with gears, and a tungsten alloy shielding plug is installed at the same time. The radiation source carrier 7 and the radiation collimator 8 rotate around the axis 14, and they are all connected to the shielding body 15 , then the focusing body 1 is formed, and at least two focusing bodies 1 are installed on the shielding body 15 according to different angles in space, the inner shaft 11 is connected with the intensity-modulating plate 2, and the inner sleeve shaft 13 is equipped with a gear, which is collimated with the ray The gears connected to each other are engaged; the outer shaft 12 is equipped with gears, which are engaged with the gears on the radioactive source carrier 7 . The shielding body 15 links to each other with the shielding doors 4, 16, and the inner shaft 11, the outer shaft 12, and the inner shaft 13 are connected w...

Abstract

The directional strengthen regulating radiotherapeutic apparatus includes shielding and protecting assembly, focusing units, strengthen regulating board and driving mechanism. The advantage of the present invention is that the independently rotated and focused units may be laid in different angles to focus the dispersive rays, such as gamma rays, onto the disease focus, so that the disease focus obtains high energy irradiation while the health tissue obtains very lower irradiation, reaching stereo directional treatment. By means of the control of the switches and speeds of the focusing units and the strengthen regulating board, the spatial distribution of the dosage absorbed by the disease focus is regulated and the important tissue of the patient may be protected by means of the independent switching function.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a directional intensity-modulated radiation therapy device. Background technique [0002] Currently existing intensity modulation devices, such as dynamic multi-leaf gratings, need to be used in conjunction with medical linear accelerators. If stereotactic therapy is required, it is necessary to attach a stereotactic isocentric device (commonly known as X-knife) to a medical linear accelerator or use a special stereotactic radiotherapy device, such as a gamma knife, but the latter cannot perform conformal intensity-modulated therapy. The equipment investment is big like this, and operation and use are complicated. Contents of the invention [0003] The purpose of the present invention is to design a radiotherapy device with low price, easy popularization, stereotactic radiotherapy and intensity modulation. [0004] The dir...
