Abstract
The invention discloses a method and a system for improving liver intervention targeted positioning accuracy. The method comprises the following steps: acquiring first focus information of a first user according to first image information; determining a first targeted target position according to the first focus information; obtaining first blood vessel distribution information and first blood vessel attribute information according to the second image information; obtaining first interventional blood vessel path information according to a first targeted target position, the first blood vessel distribution information and the first blood vessel attribute information; determining a first interventional wound inlet; obtaining a first navigation feature list; constructing a first interventional navigation instruction chain according to the first navigation feature list; and according to the first interventional navigation instruction chain, performing liver interventional targeted localization at the entrance of the first interventional wound surface. The technical problems that in the prior art, in the arterial intubation process, the intubation positioning accuracy is not high, and positioning is not accurate or intubation cannot be accurately assisted to the focus position are solved.
Description
technical field [0001] The present invention relates to the related field of improving targeting accuracy, and in particular to a method and system for improving targeting accuracy of liver intervention. Background technique [0002] The full name of interventional therapy for liver cancer is interventional therapy for liver cancer. It is used to make tiny channels with a diameter of several millimeters on the blood vessels and skin without exposing the lesions by surgery, or through the original pipeline of the human body, in the imaging equipment (angiography machine, fluoroscopy, etc.) Under the guidance of machine, CT, MR, B-ultrasound), it is the least traumatic treatment method to treat the lesion locally. Interventional therapy for liver cancer refers to a regional local chemotherapy method in which anticancer drugs or embolic agents are injected into the hepatic artery through femoral artery catheterization. [0003] However, in the process of realizing the technica...
