An electrocardiographic ultrasound signal fusion tomographic imaging system and method

Abstract

The invention relates to a medical examination and diagnosis method and an instrument, in particular to a multi-dimensional electrocardiographic and ultrasonic signal fusion imaging system and method based on anatomical positioning. The present invention is based on a multi-dimensional electrocardiographic signal imaging system and method, and further integrates multi-dimensional ultrasonic cardiac structure and perfusion imaging technology to provide a new non-invasive platform for recording and evaluating the electrical-mechanical signal characteristics and myocardial perfusion of the heart. feature. It is a unique synchronous tomographic imaging method of electromechanical function and perfusion based on anatomical positioning, a non-invasive imaging technique for detecting transmural electrocardiographic activity information and mechanical signals. The present invention can improve the diagnosis of myocardial diseases such as myocardial hypertrophy, cardiomyopathy, myocardial infarction, myocarditis, etc. and the determination of the origin of arrhythmia, etc., and provides a brand-new tool for diagnosis and guiding treatment for rapid real-time diagnosis of heart diseases.

Description

technical field [0001] The invention relates to a medical examination and diagnosis method and an instrument, in particular to a multi-dimensional electrocardiographic and ultrasonic signal fusion imaging system and method based on anatomical positioning. Background technique [0002] Cardiac electrical excitation and the resulting mechanical activity are the two most basic physiological features of the heart. The former reflects the self-discipline, excitability and electrical conductivity of the cardiac excitatory tissue, while the latter reflects the rhythmic contraction and relaxation of myocardial tissue to maintain the body's blood circulation. The electrical excitation and mechanical activity of the heart are closely related, which is called Electrical-Mechanical (E-M) Coupling physiologically, and this coupling is a necessary condition for ensuring the normal function of the heart. Many heart diseases can cause cardiac electrical activity and mechanical dysfunction....

Problems solved by technology

Although one-dimensional electrocardiogram has been used in the field of clinical diagnosis in two-dimensional plane and three-dimensional ultrasound, it is limited to simple ECG monitoring and synchronous detection of one-dimensional electrocardiogram in the process of ultrasound examination, and does not have synchronization in two-dimensional and three-dimensional levels. Detect and evaluate the characteristics of electro-mechanical signals of organs or tissues, and implement synchronous fusion imaging of functions of real echocardiography and ultrasound signals, not to mention the implementation of tomographic imaging of synchronous acquisition and fusion of echocardiography and ultrasound signals based on anatomical positioning
