Embodiment 1

[0024] like figure 1 As shown, the embodiment of the present application provides a method for improving the accuracy of liver intervention targeting positioning, wherein the method is applied to a liver intervention targeting positioning system, and the system is connected to an imaging device in communication. The method include:

[0025] Step S100: Obtain first image information through the imaging device;

[0026] Specifically, the liver intervention targeting positioning system is a system that assists intubation therapy at the lesion position, and the imaging equipment includes ultrasound, CT, magnetic resonance (MRI plain scan + enhanced), DSA angiography, PET in One or more, and the liver intervention targeting positioning system is communicatively connected with the imaging device, and can perform mutual information interaction, and obtain relevant image information including the lesion position of the first user through the imaging device, that is, the the first im...

Embodiment 2

[0079] Based on the same inventive idea as the method for improving the targeting accuracy of liver intervention in the previous embodiment, the present invention also provides a system for improving the targeting accuracy of liver intervention, such as figure 2 As shown, the system includes:

[0080] A first obtaining unit 11, the first obtaining unit 11 is configured to obtain first image information through an imaging device;

[0081] A second obtaining unit 12, the second obtaining unit 12 is configured to obtain the first lesion information of the first user according to the first image information;

[0082] A first determining unit 13, configured to determine a first targeting target position according to the first lesion information;

[0083] A third obtaining unit 14, the third obtaining unit 14 is configured to obtain second image information through the image device;

[0084] A fourth obtaining unit 15, configured to obtain first blood vessel distribution informat...

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...
