Abstract

The invention relates to the technical field of interventional radiology arterial embolism, and discloses a radioembolism dose and injection position evaluation method based on fluid dynamics. Medical imaging images are acquired and preprocessed, and an artery tree is subjected to recognition and three-dimensional reconstruction by using the trained deep learning model and an accurate modeling method; segmenting and naming the reconstructed blood vessel; obtaining the flow of each blood vessel outlet of the embolism part based on fluid dynamics, and calculating embolism efficiency and organ injury conditions during injection at different embolism positions based on the flow of each blood vessel outlet of the embolism part; the method comprises the following steps: calculating the microsphere radiation quantity of each blood vessel outlet based on a flow ratio, then analyzing the radiation dose and distribution of the microspheres by using a statistical simulation method, drawing a radiation dose distribution three-dimensional cloud chart, and evaluating the damage degree of organs based on the radiation dose of the microspheres to ensure the treatment effect on tumors.

Description

technical field [0001] The invention relates to the technical field of interventional radiology arterial embolization, in particular to a hydrodynamic-based radioembolization dose and injection position evaluation method. Background technique [0002] Radioembolization is a combination of radiation therapy and a medical procedure called "arterial embolization", which is currently used mainly to treat cancer. In short, tiny particles containing radioactive substances are injected into the blood vessels, which flow through the bloodstream and eventually block the blood flow to the cancer cells. [0003] However, at present, it is difficult to accurately predict the position of injected particles and embolization efficiency, and control and adjust them with high precision, and it is even impossible to evaluate the damage degree of radioembolization operation to human organs in real time and dynamically, which seriously affects the therapeutic effect of arterial embolization. ...
