Problems solved by technology

However, the integrated CT treatment system in the prior art can only achieve image guidance before treatment and correct the position error between fractions, but cannot achieve real-time imaging during the treatment process, so as to realize the guidance of the accelerator (treatment source) on the Movement targets for monitoring, gating or tracking therapy
Furthermore, although the DR system in the prior art can achieve imaging during treatment, it cannot meet the needs of precise radiotherapy.
Furthermore, although the diagnostic-level image-guided therapy system in the prior art can realize real-time imaging during the treatment process, its structure is complex and the cost is high

Embodiment 1

[0050] This embodiment provides an image-guided treatment structure. Specifically, please refer to figure 1 , which schematically shows the structure diagram of the image-guided treatment structure provided in this embodiment. from figure 1 It can be seen that the image-guided treatment structure provided in this embodiment includes a gantry 211 , a treatment source 212 disposed on the gantry 211 , a plurality of radiation sources 213 , and a plurality of radiation sources 213 corresponding to the gantry 211 . a plurality of detectors 214; and a plurality of the radiation sources 213 are arranged along the circumference of the frame 211, and a plurality of the detectors 214 are arranged along the circumference of the frame 211; the radiation sources 213 The imaging beam of 100 intersects the treatment area 100 with the treatment beam of the treatment source 212 .

[0051] Therefore, in the image-guided treatment structure provided by the present invention, a plurality of the...

Embodiment 2

[0063] The difference from the image-guided treatment structure provided in the first embodiment is that the multiple radiation sources 213 and the multiple detectors 214 of the image-guided treatment structure provided in this embodiment do not follow the gantry 211 to rotate. In order to avoid repetition, only the differences are described below, and for other parts that are not described, please refer to the relevant description of the first embodiment.

[0064] Specifically, see image 3 , image 3 This is a schematic structural diagram of the image-guided treatment structure provided in the second embodiment of the present invention. from image 3 It can be seen that the gantry 211 of the image-guided treatment structure provided in this example includes an annular housing 211b and a gantry body 211a, a plurality of the radiation sources 213, a plurality of the detectors 214, and the gantry body 211a and the treatment source 212 are located within the annular housing ...

Embodiment 3

[0067] This embodiment provides an image-guided treatment method, which is used in the image-guided treatment structure described in any of the foregoing embodiments. Specifically, see Figure 4 , which schematically presents the flow chart of the image-guided therapy method, starting from Figure 4 It can be seen that the image-guided treatment method provided by this example includes the following steps:

[0068] S100: Acquire treatment planning information and / or imaging information; wherein, the treatment planning information includes the outgoing period, and the pulse width and / or the outgoing duty cycle of the treatment beam of the treatment source; the imaging information includes imaging point in time.

[0069] S200: According to the treatment plan information, control the radiation source to emit an imaging beam at the beam exit gap of the treatment beam of the treatment source, so as to image the target area under treatment in real time; and / or according to the ima...

Abstract

The invention provides an image-guided treatment structure, method, device and system, the image-guided treatment structure comprises a frame, and a treatment source, a plurality of radiation sources and a plurality of detectors corresponding to the plurality of radiation sources arranged on the frame; the plurality of radiation sources are arranged in the circumferential direction of the rack, and the plurality of detectors are arranged in the circumferential direction of the rack; an imaging beam of the radiation source and a treatment beam of the treatment source intersect at a treatment area. Therefore, the imaging area of the radiation source can coincide with the treatment area of the treatment source, real-time imaging in the treatment process can be achieved, doctors are better helped to conduct monitoring, gating treatment and tracking treatment on the target area, diagnosis and treatment efficiency is improved, and a treatment plan is adjusted in real time.

Description

technical field [0001] The present invention relates to the technical field of medical devices, in particular to an image-guided treatment structure, method, device and system. Background technique [0002] CT (Computed Tomography), that is, electronic computed tomography, which uses precisely collimated X-ray beams, gamma rays, ultrasonic waves, etc., together with a highly sensitive detector, makes a cross-sectional scan around a certain part of the human body one by one. It has the characteristics of fast scanning time and clear images, and can be used for the inspection of various diseases. At the same time, radiotherapy plays an increasingly important role in tumor treatment. In order to irradiate the tumor site more accurately and better protect the critical organs around the tumor, a variety of imaging methods are used in the field of image-guided radiotherapy (IGRT). Including kV CBCT, kV FBCT, PET-CT, and MR. However, the integrated CT treatment system in the prio...
