Dynamic display method and system for heart cavity

Abstract

The invention discloses a dynamic display method and system for heart cavity. The method comprises the following steps: acquiring a plurality of groups of cardiac medical images at equal intervals of a complete heartbeat period which are continuous ones in terms of the time sequence; segmenting the endocardium and the epicardium of the heart cavity in each group of the cardiac medical images to obtain the endocardial contour and the epicardial contour of the heart cavity in each group of the cardiac medical images; according to the endocardial contour and the epicardial contour, constructing three-dimensional models for the heart cavity; adding a plurality of three-dimensional transition models of the heart cavity into the three-dimensional models; and displaying the plurality of three-dimensional models and the plurality of three-dimensional transition models dynamically in the time sequence. The method and system disclosed by the invention realize the non-intruding type four-dimensional dynamic display of a heart cavity. Capable of being operated conveniently, the method and system do not cause any damage to a human body; and in the modeling process, the used data information can be used to calculate the cardiac muscle momentum, endometrial momentum and heart cavity volume and other parameters so as to facilitate the development of various expansion functions.

Description

technical field [0001] The invention relates to the fields of medical detection and computer simulation, in particular to a method and system for dynamically displaying heart chambers. Background technique [0002] The heart is one of the important organs of the human body, and cardiovascular disease is one of the three major human diseases, so it is of great significance to study its physiology and pathology. What is common: If a person dies suddenly and unexpectedly, there is usually an underlying heart problem. The high incidence of cardiovascular diseases and so on urgently require people to study the physiological structure of the heart and the related physiological activities of the heart. [0003] With the rapid development of modern biomedical engineering, many technical methods for non-invasive diagnosis of heart diseases have emerged. The promotion and application of modern medical imaging technologies such as CT, magnetic resonance and ultrasound imaging, as wel...

AI Technical Summary

Problems solved by technology

The existing method of placing a catheter in the heart is an invasive method, which is harmful to the human body and inconvenient to operate; and this method can only achieve real-time four-dimensional imaging without building a four-dimensional dynamic model, so it is difficult to analyze the relevant spatial data Do extraction and processing, so that it will cause inconvenience to the development of extended functions in the future
