Abstract

The present invention discloses a method and a system for extracting data parameters of left auricle based on CT images. The method comprises the following steps: acquiring a coronary artery CTA imagesequence; performing three-dimensional reconstruction on the coronary artery CTA image sequence to obtain a three-dimensional coronary artery image; utilizing the three-dimensional coronary artery image and a pre-established left atrium segmentation model to obtain a left atrium three-dimensional image; extracting data parameters of left auricle from the left atrium three-dimensional image, wherein the data parameters of left auricle at least comprise a left auricle opening position, a left auricle opening area, a left auricle opening longest diameter, a left auricle opening shortest diameterand a left auricle depth; and generating an image analysis report according to the extracted data parameters of left auricle. The method and system for extracting data parameters of left auricle based on CT images can obtain diversified three-dimensional data of left auricle efficiently, rapidly and accurately and provide effective reference for follow-up clinical evaluation and scientific research analysis.

Description

technical field

[0001] The invention relates to the field of image processing, in particular to a method and system for extracting left atrial appendage data parameters based on CT images. Background technique

[0002] The left atrial appendage is an ear-shaped sac protruding from the left atrium, which is a part of the left atrium and is the main component of the left atrium. Left atrial appendage closure is currently a new trend in the treatment of stroke prevention in patients with atrial fibrillation around the world. It can effectively reduce the mortality and disability of patients, and reduce the occurrence of bleeding at the same time. Due to the complex anatomy of the left atrial appendage, in the prior art, doctors usually use CT imaging to evaluate the shape and variation of the left atrial appendage based on clinical experience, and perform related measurements to determine the anatomical structure of the left atrial appendage Related parameters provide data ref...
