초록
의료 영상학 분야에서 증강현실은 의료 영상 정보를 보다 효과적으로 가시화하기 위해서 다양한 형태로 응용되어왔다. 특히 프로젝션 기반의 증강현실은 의사가 디스플레이 장치의 화면을 자주 모니터링 해야 하거나 HMD(Head-Mounted Display)와 같은 증강현실 디스플레이 장치를 지속적으로 착용해야 하는 불편함 없이 환부에 직접 투사함으로써 의사에게 보다 편리하고 직관적으로 의료 영상 정보를 제공할 수 있게 하였다. 본 논문에서는 이런 의료 영상 정보 가시화 기술을 의료용 직접투사 증강현실(MeDAR: Medical Direct-Projected Augmented Reality)이라 부르고MeDAR의 영상 정보 가시화 프레임워크와 이를 구현하기 위한 제반 기술을 제시한다. 또한 수술 환경에서 발생할 수있는 다양한 투사 환경에 적절하게 대응할 수 있는 MeDAR의 요소 기술을 설명한다. 마지막으로 인간 친화적인 펜기반의 인터페이스를 제시하여 사용자와 MeDAR 간의 상호작용에 관해 논의하고 그 유용성을 확인한다.
Abstract
In the field of medical imaging, augmented reality has widely been used for visualizing medical information. Projection-based augmented reality, in particular, has enabled intuitive and convenient visualization of medical information by directly projecting it onto surgical targets without frequently monitoring displays or continuously wearing augmented reality displays such as head-mounted displays (HMDs). In this paper, we call such visualization technology of medical information medical direct-projected augmented reality (MeDAR) and present its visualization framework with fundamental techniques. Practical solutions to flexibly adapt to real surgical environment are also explained. Finally, user interactions with MeDAR are discussed by proposing a human friendly pen-based interface.
