Embodiment Construction

[0041] Glossary:

[0042] Cardiac anatomical tomography: the process of obtaining relevant biological signals in two or three dimensions from the apex to the base of the heart (such as Figure 4A , 4B The ECG signals of the anatomical parts of the 16-segment left ventricle are acquired synchronously according to the anatomical structure).

[0043] Electrocardiographic tomography: Electrocardiographic tomography refers to the ECG signals of different anatomical sections of the heart, scanning heart electrical activity in two or three-dimensional cross-sections of the heart, such as cardiac transmural potential, electrocardiogram, and electrocardiographic activation maps such as depolarization, complex polarized mode. Its anatomical section positioning adopts the currently internationally accepted American Heart Association's cardiac anatomical section, which is a general section of international cardiac medical imaging technology, including ultrasound technology. This invent...

Abstract

The invention relates to a medical examination diagnostic method and instrument, in particular to an electrocardio tomography imaging system and method. The electrocardio tomography imaging method is unique, is based on anatomical positioning, and is a non-invasive imaging technology used for detecting transmural electrocardio activity information (including a heart transmural electric potential, an electrocardiogram, an electrocardio activation map depolarization mode, and an electrocardio activation map repolarization mode). According to the electrocardio tomography imaging system and method, diagnosis of myocardium diseases such as myocardial hypertrophy, cardiomyopathy, myocardial infarction and myocarditis can be improved, sources of arrhythmia can be determined, and a novel diagnosis and treatment guidance tool is provided for quick real-time diagnosis of myocardial diseases.

Description

technical field [0001] The invention relates to a medical examination and diagnosis method and instrument, in particular to an electrocardiographic tomography imaging system and method based on anatomical positioning. Background technique [0002] Cardiac electrical activity is one of the most basic physiological functions of the heart. This activity reflects the automaticity, excitability and electrical conductivity of the excitatory tissue of the heart. Many heart diseases can cause abnormal electrical excitation and conduction of the heart, and detecting the electrical activity of the heart is an important part of diagnosing and treating heart diseases. The techniques currently used to detect cardiac electrical activity can be summarized into the following aspects: [0003] 1.1 One-dimensional electrocardiogram (ECG): [0004] The electrical activity of the heart is recorded indirectly through the body surface. This activity reflects the depolarization and repolarizat...
