摘要：
An imaging system with two modalities has a catheter with an optical lens system situated at an end of the catheter and optically connected to optical guide. The lens system has a numerical aperture which is changeable between a first aperture and a second larger numerical aperture. The imaging system also has an imaging unit for optical imaging with the catheter. First and second imaging modalities are optically connectable with the optical lens system of the catheter. The imaging system can change between imaging in two modes: (1) the first numerical aperture of the optical lens system and the first imaging modality of the imaging unit, and (2) the second numerical aperture of the optical lens system and the second imaging modality of the imaging unit.
