Embodiment

[0053] like figure 1 As shown, the radioactive particle source implanted needle track path planning and needle track generation method in this embodiment includes parallel needle track path planning and needle track generation and free-angle needle track path planning and needle track generation;

[0054] Parallel needle track path planning and needle track generation include the following steps:

[0055] S101. Arranging the radioactive particle sources linearly and horizontally in the tumor, and drawing the tumor as a model of the segmented tumor surface;

[0056] S102. Divide the tumor into multiple X*1*1cm squares according to the direction of the linear and horizontal arrangement of the radioactive particle sources, where X is the length, width or height of the tumor;

[0057] S103. Extending both ends of each block outward;

[0058] S104. If the extensions in the same direction of all the squares do not touch the endangered organs and tissues outside the tumor, use the ...

Abstract

The invention discloses a method for planning a path of a radioactive particle source transplant needle track in tumor bodies and generating a needle track. The method comprises the steps of planninga parallel needle track path, and generating a needle track; S101, enabling radioactive particle sources to be in linear and horizontal distribution in tumors; S102, according to the linear and horizontal distribution of the radioactive particle sources, dividing the tumors into a plurality of rectangular blocks; S103, enabling two ends of each of the rectangular blocks to extend outwards; and S104, if the equidirectional extension segment of each of the rectangular blocks does not come across damaged organs and tissue outside the tumors, generating the needle track by using the center line ofeach rectangular block of the tumors as a reference line, if the total quantity of the damaged organs and tissue outside the tumors in the equidirectional extension segments is greater than or equalto a set value, rotating the tumors to the best angle, generating the needle track by using the center line of each of the rectangular blocks of the tumors at the rotating angle as the linear reference line, and planning the free-angle needle track path and generating the needle track. According to the method disclosed by the invention, the needle tracks are reasonably planned, and additional damage to other tissue in bodies can be avoided.

Description

technical field [0001] The invention belongs to the technical field of radioactive particle implantation, and in particular relates to the path planning of a radioactive particle source implanted in a tumor and a method for generating a needle path. Background technique [0002] Interstitial radioactive particle implantation (also known as brachytherapy) therapy is to implant micro-radiation sources (particles) into tumors or tissues infiltrated by tumors, including tissues where malignant tumors have spread along the lymphatic route, and emit radioactive particles through the source of radioactive particles. Continuous low-energy γ-rays cause tumor tissue to suffer maximum radiation damage and destruction, while normal tissue is not damaged or only slightly damaged, so as to achieve the purpose of treatment. According to the seed implantation time, it can be divided into permanent implantation method and non-permanent implantation method. Experts believe that compared with...
