의학촬영

의학촬영

의학촬영(醫學撮影, 영어: medical imaging) 또는 의학영상은 의료에서 인체 내부의 숨겨진 구조 등을 시각화하는 것이다. 의료 초음파방사선촬영, MRI, 내시경, PET 등의 기술이 있다.

의학촬영은 임상 분석 및 의학적 개입뿐만 아니라 일부 장기 또는 조직의 기능(생리학)을 시각적으로 표현하기 위해 신체 내부를 영상화하는 기술 및 프로세스이다. 의학촬영은 피부와 뼈에 숨겨진 내부 구조를 밝히고 질병을 진단하고 치료하는 것을 목표로 한다. 의학촬영은 또한 이상을 식별할 수 있도록 정상적인 해부학 및 생리학에 대한 데이터베이스를 구축한다. 제거된 장기 및 조직 (생물학)의 영상화는 의학적 이유로 수행될 수 있지만 이러한 절차는 일반적으로 의학촬영화 대신 병리학의 일부로 간주된다.

뇌전도(EEG), 뇌자도(MEG), 심전도(ECG) 등과 같이 기본적으로 영상 생성을 위해 설계되지 않은 측정 및 기록 기술은 매개변수 그래프 대 시간 또는 맵으로 표현되기 쉬운 데이터를 생성하는 기타 기술을 나타낸다. 측정 위치에 대한 데이터가 포함되어 있다. 제한된 비교에서 이러한 기술은 다른 의료기기 분야의 의학촬영 형태로 간주될 수 있다.

2010년 기준 전 세계적으로 50억 건의 의학촬영 연구가 수행되었다.[1] 2006년 의학촬영으로 인한 방사선 노출은 미국 전체 전리 방사선 노출의 약 50%를 차지했다.[2] 의학촬영 장비는 CMOS 집적 회로 칩, 전력 반도체 장치, 이미지 센서(특히 CMOS 센서) 및 바이오 센서와 같은 센서, 마이크로컨트롤러, 마이크로프로세서, 디지털 신호 프로세서, 미디어 프로세서 및 시스템 온 칩 장치와 같은 프로세서를 포함하여 반도체 산업의 기술을 사용하여 제조된다. 2015년 기준 의료영상칩 연간 출하량은 4,600만개, 11억 달러에 이른다.[3]

"비침습적"(noninvasive)이라는 용어는 사용되는 대부분의 영상 기술에서와 같이 환자의 신체에 기구를 삽입하지 않는 절차를 나타내는 데 사용된다.
