Problems solved by technology

However, this method only extracts the characteristic data of the left ventricle, and does not consider the parameters of the left ventricle and the right ventricle at the same time, which will affect the accuracy of diagnosis; and the 13 parameters extracted are not specifically for the diagnostic index of DCM, so this method cannot Make an Accurate Diagnosis of DCM

Embodiment

[0071] This embodiment provides an automatic diagnosis system for human dilated cardiomyopathy, which includes: computer equipment and a server, and the server stores cardiac images of a patient in one cardiac cycle. The computer equipment includes a memory, a processor, and a computer program stored on the memory and operable on the processor. When the processor executes the program, the following steps are implemented, such as Figure 1-7 shown, including:

[0072] (A) Input cardiac images within one cardiac cycle, from which end-diastolic (ED) and end-systolic (ES) images are determined and selected.

[0073] The cardiac image may be one of cardiac magnetic resonance imaging, cardiac CT or cardiac ultrasound image, and the cardiac image used for example in this embodiment is parasternal short-axis cardiac magnetic resonance imaging (CMRI). Cardiac magnetic resonance imaging (cardiac magnetic resonance cine) is a magnetic resonance imaging technique that continuously collec...

Abstract

The invention relates to the technical field of diagnosis of dilated cardiomyopathy (DCM), in particular to an automatic diagnosis system for human dilated cardiomyopathy. The system provided by the invention can realize the following diagnosis process: a heart image in a heart cycle is used as original data to be input, and a computer program can judge an end diastole image and an end systole image from the original data to segment a left ventricle and a right ventricle; and then heart parameters capable of reflecting the strain information of the left ventricle, the right ventricle and the ventricular muscle wall are calculated. After heart parameters are obtained, features of the heart parameters are input into a classifier, and DCM patients and non-DCM patients can be distinguished. The end-to-end full-automatic DCM diagnosis is realized, and compared with manual or semi-automatic diagnosis, the end-to-end full-automatic DCM diagnosis method has a good application prospect.

Description

technical field [0001] The technical field of dilated cardiomyopathy (DCM) diagnosis of the present invention particularly relates to an automatic diagnosis system for human dilated cardiomyopathy. Background technique [0002] Dilated cardiomyopathy (DCM) is a primary heart disease of unknown cause that can lead to impaired left ventricular systolic function, heart valve disease, supraventricular arrhythmia, thrombosis, progressive heart failure, and even sudden death. Patients with DCM have a poor prognosis, with a five-year mortality rate of up to 20%. [0003] In the early stage of the disease, the ventricular muscle wall in DCM patients may also show varying degrees of thickening. In the middle and late stages of the disease, cardiomyocytes in DCM patients are hypertrophic, but the ventricular wall thickness is generally normal or relatively thin due to dilation of the cardiac chambers. Clinical manifestations of DCM can occur in all age groups, and the incidence of m...
