In our previous reports we demonstrated a novel Fourier domain optical coherence tomography method, Master Slave
optical coherence tomography (MS-OCT), that does not require resampling of data and can deliver en-face images from
several depths simultaneously. While ideally suited for delivering information from a selected depth, the MS-OCT has
been so far inferior to the conventional FFT based OCT in terms of time of producing cross section images. Here, we
demonstrate that by taking advantage of the parallel processing capabilities offered by the MS-OCT method, cross-sectional
OCT images of the human retina can be produced in real-time by assembling several T-scans from different
depths. We analyze the conditions that ensure a real-time B-scan imaging operation, and demonstrate in-vivo real-time
images from human fovea and the optic nerve, of comparable resolution and sensitivity to those produced using the
traditional Fourier domain based method.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for most presentations.
