Radiotherapy system

Abstract

The invention relates to a radiotherapy system, which comprises a treatment head, a treatment head supporting frame, a rotary mechanism for driving the treatment head, a treatment bed and a CT imaging device, wherein the CT imaging device comprises a CT imaging ring, a CT drive mechanism connected with the CT imaging ring and a CT supporting frame for supporting the CT imaging ring; the radiotherapy system also comprises a shared bracket; the treatment head supporting frame is connected with the shared bracket by a bearing; the CT supporting frame is connected with the shared bracket by a Z-direction guide rail in the vertical direction and a X-direction guide rail in the horizontal direction; the treatment bed comprises a base and a human body supporting plate; the human body supporting plate is connected with the base by a Y-direction guide rail along the direction of a shaft line of a central hole of the CT imaging ring; the base is fixedly connected with the CT supporting frame; and the shared bracket, the treatment head supporting frame and the CT supporting frame are all provided with spaces for the treatment bed to pass through and are communicated with the central hole of the CT imaging ring. The radiotherapy system solves the technical problem that the CT imaging device and the treatment head rotate at the same time to cause poor imaging effect of the CT imaging device and the spaces of the CT imaging device and the treatment head are incompatible so as to influence an effect.

Description

technical field [0001] The invention relates to a radiotherapy system, in particular to a radiotherapy system with images. Background technique [0002] Existing radiotherapy systems include treatment heads, treatment head drive mechanisms and treatment couchs, and some also include CT imaging devices, but the CT imaging devices in existing radiotherapy systems with CT imaging devices rotate simultaneously with the treatment head, and Generally speaking, the rotation speed of the treatment head is very different from that of the CT imaging device. In order to ensure the treatment effect, the imaging effect of the CT imaging device is very poor. In addition, due to the space required for CT imaging, that is, the aperture of the CT imaging ring is small, In radiation therapy, especially systemic therapy, the treatment space is relatively large, so if the two are simply combined, the imaging space and the treatment space will be incompatible, and even affect the working effect ...
