Embodiment Construction

[0009] refer to figure 1 , the X-knife treatment device includes a treatment head (6) and its moving frame, and the moving frame includes a sequentially connected vertical telescopic arm (5), a vertical rotary arm (4), a horizontal moving guide rail (2) and a slide block (3) ), horizontal fixed guide rail (1) and slider (3): the treatment head (6) is connected with the vertical telescopic arm (5), and the treatment head (6) includes an accelerator, a target and a collimator to generate radiation required for treatment . The horizontal moving guide rail (2) moves in the X direction along the horizontal fixed guide rail (1) through the slider, and the vertical slewing arm (4) moves in the Y direction along the horizontal moving guide rail (2) through the slider (3). In addition, the vertical telescopic hip ( 5) Move up and down along the vertical axis Z, so that the treatment head (6) can reach any point in the space within the range of motion, through the rotation of the verti...

Abstract

The invention discloses a three-dimensional directional radiotherapy device, and relates to medical radiotherapy equipment, in particular to the therapy device using radioactive rays generated by an accelerator to act on the whole human body. The therapy device comprises a therapy head and a moving machine frame, wherein the moving machine frame comprises a vertically stretching mechanism, a vertically rotating mechanism, a horizontal moving guiding mechanism and a horizontally fixing guiding mechanism which are sequentially connected. The three-dimensional directional radiotherapy device is simple in structure and high in positioning precision and convenient to control. The scanning tracks of the radioactive rays of the therapy head can be optionally adjusted according to therapy needs.

Description

1. Technical field [0001] The invention proposes a stereotaxic radiotherapy device, which relates to medical radiotherapy equipment, in particular to a treatment device that utilizes radiation generated by an accelerator to act on the whole body of a human body. 2. Background technology [0002] The background technology of the present invention is a treatment device for irradiating human diseased tissues with scanning focused electron beams or X-rays. Existing medical stereotaxic radiation therapy devices, such as X-knife devices, generally use the planar mechanical rotation of the accelerator treatment head and the rotation of the treatment bed around the isocenter with different displacement angles. The area scanned by radiation during treatment is very limited. U.S. Patent No. 5 2 61 2 9 4 discloses a technology for directional focusing of radiation, which uses an electromagnetic focusing device to deflect the radiation in a plane and enter the common focus, and moves th...
