Control System of the Scanning Magnetocardiography

Abstract

The magnetocardiography (MCG) is a noninvasive diagnostic tool for cardiac current activity. The clinical investigation shows the MCG has better detection results than ECG and could reveal more information about the heart. The multichannel MCG could cover enough surface area of the chest, but at the same time will increase the cost of the system, which is one of the critical reasons why MCG cannot be widely promoted. In this study, a scanning magnetocardiography system was developed oriented towards low cost, which can detect enough area by the scanning method. The control system realizes the control of the hardware and the processing of the data and can complete the detection of MCG automatically. The effectiveness and reliability of the control system are provided by experiments.
