Stereoscopic Imaging Technology for Medical Video Endoscope

摘要

With the development of the minimally invasive surgeries (MIS), the quality of information provided to surgeons becomes more and more important. Consequently it has been a trend that stereoscope replaces the traditional monocular endoscopes. This 3D video endoscope system acquires separate left and right images by a pair of stereo-objective lenses replicating human binocular vision. The system employs time multiplexing technique accomplished by images processor. The separate left and right images will been seen with an active matrix liquid crystal screen and a circular polarized eyewear at different moments at the same time. The clinical evaluation shows that when the system is adopted to perform the MIS, the procedure is safer, more effective, and less invasive.
