      Feature Of The Week 11/25/12: Nicolaus Copernicus University Presents Work on Four-Dimensional OCT Imaging Using Graphics Processing Units

      Nicolaus Copernicus University present the application of graphics processing unit (GPU) programming for real-time three-dimensional (3-D) Fourier domain optical coherence tomography (FdOCT) imaging with implementation of flow visualization algorithms. One of the limitations of FdOCT is data processing time, which is generally longer than data acquisition time. Utilizing additional algorithms, such as Doppler analysis, further increases computation time. The general purpose computing on GPU (GPGPU) has been used successfully for structural OCT imaging, but real-time 3-D imaging of flows has so far not been presented. NCU has developed software for structural and Doppler OCT processing capable of visualization of two-dimensional ...

      Method And Apparatus For Optical Coherence Tomography
      The invention relates to optical coherence tomography (OCT), more specifically to spectral optical coherence tomography (SOCT). The invention deals with problem of artefacts occurring in certain scan positions due to sharp increases of reflection by the object under investigation. It solves this problem by using an extra intensity sensor located at an output for non-dispersed light of the dispersive element used for spectral analysis, e. g. in the zero order of a diffraction grating, and using the signal of this sensor for the modification of the interferometric data.

      Real-time imaging for Spectral Optical Coherence Tomography with massively parallel data processing
      In this paper the application of massively parallel processing of Spectral Optical Coherence Tomography (SOCT) data with the aid of a low-cost Graphic Processing Unit (GPU) is presented. The reported system may be used for real-time imaging of high resolution 2D tomograms or for presenting volume data. The overall imaging speed is over 100 frames/second for 2D tomograms built of 1024 A-scans and 9 frames/second for 3D volume images containing 100 slices of 100 A-scans. This includes t he acquisition of 2048 pixels from a CCD camera per A-scan, data transfer to the processor, all necessary processing and ...
