Abstract

The invention discloses a combined display method of a multimode image of a coronary artery. In the method of the invention, a Chinese visible human (CVH) data set and a dual source CT (DSCT) data set are respectively used to establish a three-dimensional visual model of surface rendering and a three-dimensional model of volume rendering. According to a nonrigid change mode, registration is performed to a transthoracic echocardiography (TTE) section image and a corresponding volume rendering section image. Then, a surface rendering section of a corresponding space coordinate is superposed with the TTE section image so as to overcome a difficult existing in a TTE teaching training. Abstract understanding to the TTE image is greatly influenced by subjective consciousness. Therefore, it is not convenient for understanding and mastering. By using the method provided in the invention, a medical student can visually understand and grasp the TTE and two and three level branches of the coronary artery corresponding to a corresponding myocardial segment.

Description

technical field

[0001] The invention belongs to the field of medical imaging (medical imaging technology-ultrasound medical imaging), and particularly relates to a method for jointly displaying multiple coronary artery images including echocardiography. Background technique

[0002] Transthoracic echocardiography (TTE) has the advantages of non-invasiveness, simple operation, low cost, and can provide a large amount of anatomical and hemodynamic information, and plays an important role in the diagnosis of coronary heart disease and its prognosis . In 1976, Weyman et al. first used two-dimensional echocardiography to display the main trunks of the right and left coronary arteries, and combined with coronary artery anatomy, described the characteristics of two-dimensional ultrasound images of the initial segments of the left and right coronary arteries. With the continuous development of TTE technology, TTE has become an important means of diagnosing coronary heart disease an...
