Abstract

Capsule Endoscope(CE) is a capsule-shaped electronic device which can examine the lesions in digestive tract of human body. Recently the medical procedure using capsule endoscope is receiving great attention to both doctors and patients, since the conventional push-typed endoscope using cables brings great pain and fear to the patients. The technique was firstly available in 2000 and is based on a convergence techniques among BT(Bio Technology), IT(Information Technology), and NT(Nano Technology). The device consists of an optical parts including LEDs(Light Emitting Diodes), an image sensor, a communication module and a power module. Capsule endoscope is the embodiment of the state-of-the art technology and requires key technologies in the various engineering fields. Therefore, in this paper, we introduce the composition of the capsule endoscope system, and compare the communication method between RF(Radio Frequency) communication and HBC(Human Body Communication), which are typically used for data transmission in the capsule endoscope. Furthermore, we analyze the specification of commercialized capsule endoscopes and present the future developments and technical challenges.

캡슐 내시경은 인체 내부의 소화기관 병변을 조사할 수 있는 캡슐 모양의 전자장치로서 인체 내에 케이블을 삽입하는 기존 푸시 타입(push-type)내시경과는 달리 환자에게 공포와 고통을 주지 않는 시술로 인식되고 있어, 최근 환자와 의사 모두에게 큰 관심을 끌고 있다. 이 기술은 바이오 기술(BT), 정보통신 기술(IT), 나노 기술(NT) 등의 성숙과 융합으로 2000년에 들어와 처음으로 가능하게 되었으며, LED를 포함한 광학계와 이미지 센서, 통신 모듈, 파워 모듈 등으로 구성되어 있다. 캡슐 내시경은 첨단 기술의 총체로 유비쿼터스 시대에 다양한 기술 분야의 핵심 기술을 필요로 한다. 따라서 본 논문에서는 캡슐 내시경의 구성에 관해 소개하고, 현재 데이터 전송을 위해 사용되고 있는 대표적인 RF 무선 통신 방식 및 인체 통신 시스템 방식에 대해 비교하였다. 아울러 현재 상용된 캡슐 내시경의 사양을 비교 분석하고, 미래의 캡슐 내시경의 진화 방향과 기술적 도전 과제를 제시하였다.
