Embodiment 1

[0024] Such as figure 1 The non-public radiotherapy system shown is composed of a radiation source 1, a frame 2, an image positioning system 3 and a treatment bed 4; the frame 2 is composed of a revolution base 2-1, an L-shaped rotating arm 2-2 and a C The L-shaped rotating arm 2-3 is composed of three parts. The revolving base 2-1 and the L-shaped rotating arm 2-2 are connected by a rotating pair, which can realize the revolution of the frame 2 around the central axis of the revolving base. The revolving base 2- The central axis of 1 coincides with the center line of X-rays emitted by ray source 1, that is, it is perpendicular to the ground through the isocenter point, and the L-shaped rotating arm 2-2 and the C-shaped rotating arm 2-3 are connected by a rotating pair to realize the frame 2 Rotate around the longitudinal direction of the patient; the radiation source 1 is installed on one end of the C-shaped rotating arm 2-3, and the other end of the C-shaped rotating arm 2-3...

Embodiment 2

[0028] Such as figure 2 As shown, the treatment bed support mechanism (4-3) in this embodiment is a multi-joint serial robot, and the rest of the structure is the same as that in Embodiment 1.

Abstract

The invention relates to a non-coplanar radiotherapy system in the field of medical equipment, comprising: a radiation source, a frame, an image positioning system and a treatment couch. The base and the L-shaped rotating arm are connected by a rotating pair, and the L-shaped rotating arm and the C-shaped rotating arm are connected by a rotating pair. The radiation source is installed at one end of the C-shaped rotating arm, and the other end of the C-shaped rotating arm is installed with a dose verification device , The image positioning system includes two sets of X-ray imaging systems. The two sets of X-ray imaging systems are installed on both sides of the C-shaped rotating arm. The treatment bed corresponds to the rack installation and consists of a treatment bed board, a sliding table and a treatment bed support mechanism. A rotating pair is connected between the treatment bed board and the sliding table. The non-coplanar radiotherapy system of the present invention can be used for coplanar and non-coplanar radiotherapy of head and neck tumors, orthopedic tumors, spinal tumors, etc., and the gantry has a large range of motion and high flexibility.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a non-coplanar radiotherapy system. Background technique [0002] Malignant tumor (cancer) is a major disease affecting the healthy development of the population in my country. The World Health Organization's "Global Cancer Report 2014" pointed out that nearly half of the new cancer cases occurred in Asia, most of which were in China, and China's new cancer cases ranked first. Among the four types of malignant tumors including liver, esophagus, stomach and lung, China ranks first in the world in terms of new cases and deaths. There are about 3.5 million new cancer cases in China every year, and about 2.5 million people die from it. [0003] Among the existing cancer treatment techniques, radiotherapy is a very important method. Among patients with curable tumors, the cure rate of radiotherapy can reach 12%. Therefore, the role and significance of radiotherapy are very significa...
