Research on the System Performance Test Method for MCG

心磁图仪作为一种新型医疗技术,其临床应用效果显著。为了可靠地检测心磁图仪产品,本文提出了受测者定位精度、磁场-电压转换系数、通道差异率、磁灵敏度、动态范围和系统采样率5项性能指标及其检测方法。这些指标有助于规范心磁图仪产品标准,保证其临床应用安全性和有效性。

Magnetocardiography(MCG) is a new medical technology with remarkable effect of clinical application. In order to reliably detect the magnetocardiography, 5 performance indexes and their detection methods are proposed in this paper such as positioning accuracy of the subject, the magnetic field voltage conversion coefficient, the channel difference rate, the magnetic sensitivity, the dynamic range and the system sampling rate. These indexes are helpful to specialize the product standard of MCG and ensure its safety and effectiveness in clinical application.
