Problems solved by technology

[0004] However, the above-mentioned in-stent radiotherapy in the prior art is not accurate. The position, dose and type of radiation source on the surface of the stent are roughly selected according to the experience of the doctor and installed on the stent at will, rather than by the scope of the specific lesion. , location, size, tumor cell activity, type, etc.
Moreover, this installation method does not consider how to avoid and protect normal tissues in the treatment area from radiation dose exposure
As a result, the lesion area is often not irradiated with an appropriate radiation dose, and normal tissues are subjected to unnecessary radiation damage.

Embodiment 1

[0069] Embodiment 1. After the patient is diagnosed with esophageal cancer and needs to use precise three-dimensional three-dimensional intraluminal radiotherapy, the first step is to use the three-dimensional three-dimensional quantitative analysis module for lumen lesions provided by the present invention to perform three-dimensional Stereo reconstruction. The analysis module can use the difference in density, shape, and contrast agent enhancement between cancer tissue and normal surrounding tissue to delineate the lesion area at each level, and then superimpose layer by layer to reconstruct the three-dimensional space structure of the tumor.

[0070] Then, the reconstructed three-dimensional space structure of the tumor lesion and relevant information, such as tumor pathological type, rich blood vessels, patient age, body condition, etc., are input into the radiation dose analysis module provided by the present invention, and the system will Comprehensively analyze various ...

Embodiment 2

[0073]Embodiment 2, after the patient is diagnosed with cholangiocarcinoma and needs to adopt precise three-dimensional three-dimensional intraluminal radiotherapy, the first step is to use the three-dimensional quantitative analysis module for lumen lesions provided by the present invention to perform three-dimensional stereoscopic analysis of the patient's CT / MR images. Reconstruction uses the differences in density, shape, and contrast agent enhancement between cancerous tissue and normal surrounding tissue to delineate the lesion area at each level, and then superimpose layer by layer to reconstruct the three-dimensional space structure of the tumor.

[0074] Then, input the three-dimensional spatial structure of the tumor lesion obtained from the reconstruction, and related information, such as tumor pathological type, rich blood vessels, patient age, body condition, etc., into the radiation dose analysis module provided by the present invention. The radiation dose analysi...

Abstract

The invention provides a three-dimensional precise intraluminal radiation therapy method for cancer treatment. The method includes the steps: (1) performing three-dimensional quantitative lesion measurement and analysis on three-dimensional scanned images of lesion lumens; (2) performing comprehensive analysis according to three-dimensional quantitative lesion measurement results and lesion features, and calculating a three-dimensional lesion radiation dose distribution diagram; (3) according to the three-dimensional lesion radiation dose distribution diagram, selecting proper radiation sources and radiation doses to produce stents, and performing three-dimensional precise intraluminal radiation therapy. The invention further provides a method for implementing the intraluminal radiation therapy method. Lesion tissue in the lesion lumens is subjected to three-dimensional reconstruction by means of modern medicine three-dimensional image reconstruction technology, most reasonable radiation therapy particles are mounted at proper positions of the stents, three-dimensional precise intraluminal radiation therapy is realized, cancers are treated with the optimized radiation dose, and normal tissue is protection to the largest extent.

Description

technical field [0001] The present invention relates to an internal radiotherapy method for treating tumors, in particular to a three-dimensional accurate intracavitary radiotherapy method for treating tumors, and also to a three-dimensional accurate intracavitary radiotherapy system for treating tumors, and to a three-dimensional accurate intracavitary radiotherapy system for treating tumors. The invention discloses a manufacturing method of an internal radiotherapy stent, which belongs to the technical field of medical treatment. Background technique [0002] With the development of endoscopy and interventional radiology, minimally invasive ERCP or PTCD is used to treat cholangiocarcinoma, and external drainage is changed to internal drainage. The operation is simple, and its quality of life is better than surgical bypass surgery. In 1985, Carrasco made the first expandable metal biliary stent, which achieved better treatment results. Similar treatment activities were grad...
