Embodiment Construction

[0052] First scan the ECG paper into a grayscale image, and then detect the upper and lower black edge points of the image by analyzing the grayscale histogram of the image to determine the area of ​​the ECG image. Because the scanned electrocardiogram often has a certain inclination angle, in order to obtain accurate electrocardiogram information, the present invention firstly fits the upper and lower black edges by the least squares method, obtains the slope of the straight line and then obtains the inclination angle, and adopts the bilinear difference Perform rotation correction processing, and then extract ECG curves and discretize them. After the digitized waveform filters out the interference points, the pixel and time-voltage value are transformed, and processed into a digital ECG that can be stored permanently.

[0053] The digital method of paper electrocardiogram of the present invention mainly comprises:

[0054] 1. Scan the paper ECG, and figure 2 The obtained e...

Abstract

The invention provides a method for digitalizing a paper electrocardiogram. In the method, a digital image processing technology is combined to rebuild and store a large number of clinical paper electrocardiograms. The method comprises the following steps: scanning the paper electrocardiogram, and carrying out tilt correction on the grey level image of the obtained electrocardiogram; extracting an electrocardio (ECG) curve in the paper electrocardiogram; acquiring the time-voltage value of each discrete point on the curve; rebuilding an electrocardiogram curve and leading information; storing the time-voltage value of each discrete point in a database; and storing a rebuilt oscillogram in the database. In the method, the possibility of adding symptom information of the clinically acquired paper electrocardiogram to a digital ECG information management system is ensured, thereby enriching a case bank. The method is used for solving the problems that the paper electrocardiograms are easy to damage and lose (the electrocardiograms can not be recovered after being damaged or lost), are difficult to store, and easy to go wrong in trivial management; the method facilitates clinical analysis and scientific research, thus reducing the search time, and improving the efficiency; and the method can be applied to internet medical treatment and multiple expert consultation, thus improving the diagnosis quality.

Description

technical field [0001] The invention belongs to the technical field of medical equipment and digital image processing, in particular to a method for digitizing a paper electrocardiogram. Background technique [0002] The electrocardiogram reflects the electrical activity process of the heart's excitement, and it has important reference value for the basic function and pathological research of the heart. The electrocardiogram can analyze and identify various arrhythmias; it can also reflect the degree of myocardial damage, the development process, and the functional structure of the atrium and ventricle. It is of reference value in guiding cardiac surgery and indicating the necessary drug treatment. The diagnostic content of clinical electrocardiogram is divided into the following aspects: [0003] I. Arrhythmia in coronary heart disease: Electrocardiogram is the most effective method for diagnosing various types of arrhythmia. Continuous observation of ECG in patients with ...
