Embodiment Construction

[0035] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0036] Arrhythmia refers to an abnormality in the normal rhythm of the heart, and an arrhythmia faster than the normal heart rate (60-100 beats / min) is tachyarrhythmia. In severe cases, chest pain, dyspnea, loss of consciousness, and even stroke may occur. Catheter ablation is currently a widely used method for the treatment of arrhythmias. It mainly involves inserting a catheter into the heart through puncture of blood vessels under the monitoring of an X-ray angiography machine. Release energy such as radio frequency, freezing, ultrasound, laser, etc., to necrosis the t...

Abstract

The invention relates to an image processing method and device, computer equipment, a storage medium and a mapping system, and the method comprises the steps of obtaining an imaging image which comprises a plurality of sectional images; performing three-dimensional reconstruction according to the plurality of cross-sectional images to obtain the three-dimensional image model, wherein the three-dimensional image model comprises a three-dimensional myocardial fibrosis area image; obtaining a three-dimensional electro-anatomical model, wherein the three-dimensional electro-anatomical model comprises a three-dimensional abnormal myocardial tissue image; due to the fact that a certain corresponding relation exists between the abnormal myocardial tissue area in the three-dimensional electro-anatomical model and myocardial fibrosis, registering the three-dimensional image model and the three-dimensional electro-anatomical model, and determining the overlapping portion of the three-dimensional myocardial fibrosis area image and the three-dimensional abnormal myocardial tissue image as the focus position. Accurate positioning of the focus position is achieved, and therefore the operation success rate is effectively improved.

Description

technical field [0001] The present application relates to the technical field of medical equipment, in particular to an image processing method, device, computer equipment, storage medium and mapping system. Background technique [0002] On the basis of existing medical theories, arrhythmia is often caused by abnormalities in one or more areas of the heart. Catheter ablation is currently a widely used method for the treatment of arrhythmia. It mainly involves inserting a catheter into the heart through puncture of a blood vessel under the monitoring of an X-ray angiography machine. Energy such as radio frequency, freezing, ultrasound, laser, etc., causes tissue necrosis to block abnormal signal conduction paths, so as to achieve the purpose of treatment. [0003] In the traditional technology, the three-dimensional mapping system has been widely used in the field of electrophysiology, and the ablation surgery under the guidance of the three-dimensional mapping system is als...
