<p>A stereo positioning radiation therapy device comprises: an accelerator (21), an accelerator bracket, an X-axis rotation device (13) for driving the accelerator bracket to rotate about an X-axis and a frame (1), and an adapter disposed on the accelerator bracket. The accelerator (21) is installed above the adapter, and the accelerator bracket and the frame (1) are in a transmission connection through the X-axis rotation device (13), so that the accelerator (21) can perform nodding and looking-upward actions following the accelerator bracket, thereby changing the irradiation angle of a ray emitted by the accelerator (21) with respect to a Z-axis. As a result, the irradiation angle can be adjusted in the three-dimensional space, instead of merely being changed in the two-dimensional plane originally, thereby significantly improving the degree of freedom of adjustment, which provides greater supports for accurate detection and treatment.</p> |
