Embodiment 1

[0047] The carousel image system in this example, such as figure 1 , figure 2 and Figure 4 As shown, it is composed of a C-arm imaging system 1 and a turntable 2; the C-arm imaging system 1 is composed of a C-arm base 3, a C-arm frame 4, an X-ray source 5 and a detection plate 6; the C-arm base 3 is installed on the turntable 2 The C-arm frame 4 is mounted on the C-arm base 3 , and the X-ray source 5 and the detection board 6 are mounted on the inner wall of the C-arm frame 4 on the main shaft 20 .

[0048] A treatment couch 7 is installed on the outer edge of the turntable 2, and the treatment couch 7 is installed on the treatment couch revolution platform 13, and the treatment couch revolution platform 13 and the main shaft 20 are connected by a connecting rod 19, and the connecting rod 19 and the main shaft 20 are rotating joints. Connecting, the arc track slider 15 is installed under the treatment bed revolution platform 13, and the slider 15 cooperates with the arc tr...

Embodiment 2

[0057] The turntable imaging system in this example, in addition to the X-ray source 5 and the detection plate 6, is two sets of kV-level X-ray source 5 and the detection plate 6, the angle between the two sets of imaging directions is 90 degrees, and it can rotate around the imaging center of the C-arm. At the beginning of the treatment, the information obtained by any set of X-ray source and detection board can be used for CBCT imaging to obtain a three-dimensional image for patient positioning. During the treatment process, dual-beam X-ray orthogonal imaging can be performed to obtain a three-dimensional image of the target area. Coordinates, to achieve fast positioning and real-time tracking, the rest are the same as the first embodiment.

Embodiment 3

[0059] The carousel imaging system and treatment bed 7 of this example are the same as those in Embodiment 1, such as image 3 As shown, the turntable imaging system together with the treatment couch 7, treatment system, breath tracker 9, treatment planning system and integrated control system constitute a turntable radiation therapy system, wherein the treatment system consists of a compact electron linear accelerator 10, a secondary standard Composed of a collimator 11 and a robot 12, the compact linear electron accelerator 10 is installed at the end of the mechanical arm of the robot 12, and the secondary collimator 11 is installed at the end of the compact linear electron accelerator 10; the robot 12, the treatment bed 7, and the C-arm imaging system 1. The turntable 2 and the breathing tracker 9 are connected to the integrated control system through an industrial bus; the integrated control system and the treatment planning system are connected through a network switch.

Abstract

The invention relates to a rotating disc type image system in the field of medical facilities. The rotating disc type image system is composed of a C-shaped arc image system (1) and a rotating disc (2); the C-shaped arc image system (1) is composed of a C-shaped arm base (3), a C-shaped arm support (4), an X-ray source (5) and a detecting plate (6); the C-shaped arm base (3) is installed on a main shaft (20) of the rotating disc (2), the C-shaped arm support (4) is installed on the C-shaped arm base (3), and the X-ray source (5) and the detecting plate (6) are installed on the inner wall of the C-shaped arm support (4). A treatment couch (7) is installed at the outer edge of the rotating disc (2), and is installed on a treatment couch revolution platform (13). By means of the rotating disc type image system, the shortcomings that in an existing robot radiotherapy system, image system reflection information is insufficient, the therapeutic range is smaller, and the therapeutic space is limited are overcome; the provided rotating disc type image system can conduct large-range tumor radiotherapy, and is simple in structure and easy to machine.

Description

[0001] Technical field: [0002] The invention relates to the field of medical equipment, in particular to a turntable imaging system. [0003] Background technique: [0004] Radiation therapy is one of the important means of tumor treatment, which is of great significance for improving human health and increasing human life span. Statistics provided by the World Health Organization (WHO) show that among curable cancers, the cure rate of surgery is 22%, the cure rate of combined radiotherapy and surgery is 6%, the cure rate of radiotherapy is 12%, and the cure rate of chemotherapy is only 5%. Visible, radiation therapy is an important technical means of cancer cure. [0005] Radiation therapy is based on radiation physics, radiation biology, and clinical radiation therapy, combined with knowledge of clinical oncology, surgery, internal medicine, imaging, etc., using radiation to treat diseases, mainly used to treat malignant tumors. Radiation therapy techniques have changed d...
