Abstract

The invention discloses a multimodal cardiac image visualization method, comprising: segmenting cardiac tissue structure based on the multimodal cardiac image; segmenting cardiac lesion based on the multimodal cardiac image; and combining the obtained cardiac tissue structure and cardiac lesion Superimpose to obtain a three-dimensional visualization heart image in virtual reality; and control the 3D printer through the automatic analysis of the heart tissue structure and its lesions, use elastomeric materials to print the chambers and valves of the 3D heart and combine them with mixed reality for visual display.

Description

technical field [0001] The present invention relates to the field of image processing, and more specifically, the present invention relates to methods for visualization, 3D printing and mixed reality display of multimodal cardiac images. Background technique [0002] In 2015, there were 422.7 million cardiovascular disease patients worldwide, of whom 17.92 million died from cardiovascular disease. Cardiac magnetic resonance imaging has important clinical implications for assessing ventricular function, including calculation of left ventricular end-diastolic and end-systolic volumes. In calculating these volumes, it is usually necessary to demarcate the left ventricular myocardium. Therefore, accurate segmentation of the left ventricular endocardium is a prerequisite for evaluating left ventricular function, and manual segmentation is a long and tedious process. It takes 20 minutes for a doctor to manually segment a group of cases. [0003] In order to reduce the workload o...
