To evaluate the possibility of improving the three dimensional visualization of intrasurgical OCTs using a custom built GPU based ray-traced rendering system.
Using a Carl Zeiss Meditec Cirrus HD-OCT which was adapted to the optical pathway of a Zeiss OPMI VISU 200 surgical microscope, 512x128 macular cube scans and HD 5-line scans were performed at various steps of vitreoretinal surgery. The acquired volume data was post processed and visualized using a ray-traced three dimensional display system created in the C++ based object oriented programming language COFFEE (Maxon Inc.). These visualizations were compared to the on board visualizations of the same data by the on board 4.5 Cirrus software. Informed consent had been collected from all patients.
The three dimensional rendering system developed for the project improved the quality of intrasurgical OCT in comparison to the on board rendering system.
Raytraced GPU based rendering improves the quality of three dimensional visualization of intrasurgical OCT.
