Fluorescence endoscopy video systems with no moving parts in the camera

摘要

A fluorescence endoscopy video system includes a multi-mode light source that produces light for white light and fluorescence imaging modes. Light from the light source is transmitted through an endoscope to the tissue under observation. The system also includes a compact camera for white light and fluorescence imaging, which may be located in the insertion portion of the endoscope, or attached to the portion of the endoscope outside the body. The camera can be utilized for both white light imaging and fluorescence imaging, and in its most compact form, contains no moving parts. <IMAGE>
