Abstract

In this study, we aimed to develope the physio-module for echocardiography. This physio-module includes multi-functions such as ECG, respiration, PCG, heart sound, and this is used to diagnose a cardiac disease in using ultrasound images synchronized with biosignals of physio-module. In this paper, the developed physio-module was verified by applying various test patterns considering each biosignal's characteristics and we could get the performance of QRS trigger delay time within international standard, EC-13 criteria. And ECG's change in physio-module and blood flow in M-mode was synchronized.

본 연구는 심초음파에 사용되는 생체신호측정모듈을 개발하고자 하였다. 생체신호측정모듈은 심전도, 호흡, 맥파, 심음 측정 기능을 포함하며, 생체신호측정모듈에서 측정된 4가지의 생체신호와 초음파 영상을 동기화시켜 심장의 수축과 이완에 따른 심장질환을 진단하는데 사용된다. 생체신호의 특성을 고려한 테스트 패턴을 적용하여 개발된 생체신호측정 회로부를 검증하였으며, 특히 심전도의 QRS trigger 지연시간은 국제규격인 EC-13에 만족하였다. 또한, 개발된 심전도, 호흡, 맥압, 심음이 동기화 되는 것을 확인하였으며, 심초음파의 M-mode 영상에서 혈류의 흐름과 심전도의 변화가 일치함을 확인하였다.
