연구 소개 (Research in brief)

 

MISP(Medical Imaging and Signal Processing) Lab.에서는 PET, MRI와 같은 의료영상기기 시스템에 필요한 관련 기술 연구 및 다양한 종류의 의료영상기기들을 융합시키기 위해 필요한 기술 연구, 그리고 fMRI나 PET등을 이용한 다양한 신경과학연구를 수행하고 있습니다.
기술적으로는 영상재구성 기술 개발 및 고속화와 생체 영상 처리를 주로 연구하며, 다양한 생체신호 측정 기기들의 데이터를 뇌기능, 신경과학 및 미세혈관 연구 등에서 효과적으로 활용가능케 하는 기술 및 시스템을 개발하고 있습니다.


Medical Imaging and Signal Processing (MISP) Lab is conducting the following researches : 1) research on reconstruction and processing needed for medical imaging systems such as PET and MRI, 2) research on technologies needed for effectively converging multi-modal imaging instruments and 3) research on various neuroscience using medical imaging techniques.
Recently, we are focusing on machine learning and AI techniques for the image reconstruction, processing, and denoising of various medical images. We are also developing advanced technologies and systems to effectively support the studies for brain function, neuroscience, and microvessel.
