Abstract

The invention discloses a positioning method and system for the myocardial ischemia lesion position, a storage medium and a terminal. The positioning method comprises the following steps that a magnetocardiogram dataset collected by a multichannel magnetocardiography is pre-processed, and the averaged magnetocardiogram dataset of a T wave band is obtained; based on the magnetocardiogram dataset ofthe T wave band, the magnetic strength obtained by all channels of the multichannel magnetocardiography and the channel positions of all channels of the multichannel magnetocardiography, an iso-magnetic map and a current density map of the T wave band are obtained; based on the iso-magnetic map and the current density map, feature parameters related to the myocardial ischemia lesion position areextracted; and the myocardial ischemia lesion position is judged according to the feature parameters. According to the positioning method and system for the myocardial ischemia lesion position, the storage medium and the terminal, signal features of the magnetocardiogram are analyzed, the distribution rule of the feature parameters is excavated, and thus positioning of the myocardial ischemia lesion position is assisted according to the feature parameters sensitive to the myocardial ischemia position.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a method and system for locating the position of a myocardial ischemic lesion, a storage medium and a terminal. Background technique [0002] Myocardial ischemia is a common heart disease, and its morbidity and mortality have been increasing year by year in recent years. The location of myocardial ischemia is of great value in understanding the severity of the disease, predicting the development of the disease, and specifying follow-up medical plans. Traditional cardiac imaging methods have certain limitations in the localization of myocardial ischemia. At present, cardiac tomography (CT) or coronary angiography is commonly used clinically to estimate the lesion location. Such methods are highly invasive, and patients need to bear the side effects of X-rays or angiographic contrast agents. Especially for myocardial ischemia patients with renal dysfunction, the ...
