Example Embodiment

[0035] The present invention will be further described in detail below in conjunction with specific embodiments, which are for explanation rather than limitation of the present invention.

[0036] Such as figure 1 As shown, the 3D construction method of the radioactive particle cone distribution source proposed by the present invention includes the following operations:

[0037] 1) Select the tumor area of ​​interest:

[0038] Import the prior tumor data from the imaging examination (such as ultrasound, CT, MRI and other imaging examination results) into the processor or computer, and use the segmentation method combined with manual correction to outline the tumor area of ​​interest, and generate the corresponding three-dimensional image;

[0039] 2. Set the parameters of the cone cloth source:

[0040] Including setting radioactive particle properties (for example, InterSource125, I125_Model_6711, I125_Model_6702, IR_192 and Pd_103_Model_200), radioactive particle spacing, and the dis...

Abstract

The invention discloses a three-dimensional constructing method for cone-shaped source distribution of a radioactive particle. A puncture starting point and a puncturing terminal point are defined in a three-dimensional space, and cone-shaped source distribution is carried out on the radioactive particle in a selected interested tumor area according to given parameters, so that a TPSB system can use a manner similar to a clinical actual puncture to carry out source distribution in the three-dimensional space, and further the puncture efficiency and the source distribution in the actual puncture process are improved.

Description

technical field [0001] The invention belongs to the technical field of radioactive particle source distribution, and relates to a three-dimensional (3D) construction method for radioactive particle cone-shaped source distribution. Background technique [0002] Due to its wide range, strong side effects, and strong lethality to normal tissues, conventional radiotherapy brings great pain to patients receiving treatment. In vivo Gamma Knife (three-dimensional stereotactic radiation therapy system between malignant tumor tissues) is based on the results of ultrasound, CT, MRI and other imaging examinations, and first uses the radioactive seed treatment planning system (Treatment Planning System for Brachytherapy, TPSB) to accurately design radioactive seed implantation According to the location, quantity, and implantation route, a treatment plan is formulated; then, under the guidance of CT, B-ultrasound, endoscope or direct vision of surgery, percutaneous puncture is used to im...
