Integrated 4D MIOCT system and real-time feedback to the surgeon.

(A) Photograph of the 4D MIOCT system portable cart that housed the OCT laser, interferometer, electronics and processing computer. (B) Photograph of MIOCT scanner, operating microscope and heads-up display (HUD). The HUD and MIOCT scanner integrated seamlessly into microscope. (C) Photograph of system in use during human surgery. The microscope-integrated design enabled OCT data acquisition during live surgery. (D) 4D MIOCT acquisition with the scan (green box) oriented to the axis of the surgical instrument. The MIOCT scan axis could be arbitrarily rotated and shifted laterally to scan the surgical site of interest. (E) Rotationally-offset stereo MIOCT volumes and B-scans rendered in real time. (F) Projection of the 4D MIOCT data and other supporting surgical data into the oculars for real-time OCT feedback to the surgeon.
