摘要：

We developed the ultra high-speed processing of FD-OCT images using a low-cost graphics processing unit (GPU) with many stream processors to realize highly parallel processing. The processing line rates of half range FD-OCT and full range FD-OCT were 1.34 MHz and 0.70 MHz for a spectral interference image of 1024 FFT size x 2048 lateral A-scans, respectively. A display rate of 22.5 frames per second for processed full range images was achieved in our OCT system using an InGaAs line scan camera operated at 47 kHz.
