Intraoperative spectral domain optical coherence tomography for vitreoretinal surgery.
Repository Usage Stats
We demonstrate in vivo human retinal imaging using an intraoperative microscope-mounted optical coherence tomography system (MMOCT). Our optomechanical design adapts an Oculus Binocular Indirect Ophthalmo Microscope (BIOM3), suspended from a Leica ophthalmic surgical microscope, with spectral domain optical coherence tomography (SD-OCT) scanning and relay optics. The MMOCT enables wide-field noncontact real-time cross-sectional imaging of retinal structure, allowing for SD-OCT augmented intrasurgical microscopy for intraocular visualization. We experimentally quantify the axial and lateral resolution of the MMOCT and demonstrate fundus imaging at a 20Hz frame rate.

Biophotonics is concerned with the application of cutting-edge optoelectronic technologies to problems in the biomedical sciences. My research centers on the application of optical technologies for non-invasive, high-resolution imaging and sensing in living biological tissues. The technologies we use in my laboratory include acousto-optic and integrated-optic devices, femtosecond lasers, and ultrabroadband fiber optic telecommunications equipment. The applications of the systems we build incl
