Abstract

Chronic diseases are increasing nowadays as daily habits changed due to economic growth. Among chronic diseases, heart cerebrovascular disease is one of the major causes of death in South Korea that accounts for approximately 20% of mortality. Tests to measure anomaly of the heart is ECG tests, which measures and analyzes the electrical heart activity. Any mistakes in lead attachment location critically affects ECG testings, and statistical facts showed that only 2.8% of the nurses properly located leads to patients. As a solution, this paper proposes a system based on a projection-based augmented reality technology to generate X-ray images to the patient's chest to point out exact attachment locations of ECG leads. Evaluation comparison results showed a 2.6 cm difference between the conventional system and the proposed system. ECG test results also showed significant signal differences between the systems in leads V1, V2, and V3. The ECG measured accurately by the proposed system would help greatly in patient management and clinical decisions of clinicians.

경제성장과 함께 생활습관 변화로 인한 만성질환이 지속적으로 증가하고 있다. 그 중 심뇌혈관질환은 사망원인의 약 20%를 차지하는 우리나라의 주요 사망원인이다. 심장의 이상을 측정하는 검사는 심전도검사로, 심장의 리듬을 전기적으로 측정하여 평가하는 방법이다. 심전도 검사에서 가장 영향을 미치는 것은 전극의 부착 위치인데, 간호사를 대상으로 연구한 결과에 따르면 모두 정확하게 부착한 것은 2.6%로 나타났다. 따라서 본 연구는 이러한 문제를 해결하기 위해 프로젝션 기반의 증강현실 기술을 사용하여 환자 본인의 Chest X-ray 사진을 흉부에 중첩시켜 투영시킴으로써 정확한 전극 부착위치를 쉽게 알 수 있는 시스템을 개발하였다. 기존의 방법으로 측정한 결과와 개발한 시스템으로 측정한 결과를 비교하였더니 2.6cm의 오차를 보였다. 그에 따른 심전도 결과에서도 V1, V2, V3위치에서 눈에 띄는 파형의 차이가 있었다. 본 시스템으로 정확하게 측정된 심전도는 의료진들의 환자관리 및 임상적 의사결정에 크게 도움이 될 것이다.
