re: Developing the world’s first real-time 3D OCT medical imaging system

I strongly agree with solarpower44. The FIRST realtime 3D (or 4D)OCT system was developed by the group at Johns Hopkins using GPU for both OCT image reconstruction (A-scan processing)and volume rendering. While this work uses FPGA for reconstruction and GPU volume rendering. The FPGA method has also been tried before [1,2]. Personally I prefer the GPU method with CUDA since it's the most cost effective approach. The FPGA module should also realize the function but it would cost much more money than a regular GPU. [1] T.

Hi, The image penetration depth is the length of actually acquired image in the direction of depth from the surface.

To @particle60: what is the image penetration depth? Kris

I checked the works cited by solarpower44 because I got interested in. Although they actually showed some real-time OCT, I think it is insufficient for MEDICAL IMAGING both in the image size and the image penetration depth. It seems this work's designs fit a bit better to target medical use as the title shows.

This is not true. This is not the first real-time OCT. Too bad they don't cite other works. for example: Graphics Processing Unit Accelerated Non-uniform fast Fourier transform for ultrahigh-speed, real-time Fourier-domain OCT,” Opt. Exp., vol. 18, Iss. 22, pp. 23472-23487, Oct., 2010 Real-time 4D signal processing and visualization using graphics processing unit on a regular nonlinear-k Fourier-domain OCT system,” Optics Express, Vol. 18, Issue 11, pp. 11772-11784, 2010

Agreed with SpeedEvil: it is an exciting but largely complementary technology to MRI or PET...I am editing a book on medical imaging for Wiley, looking for someone to write a chapter on OCT, if interested pls email: kris.iniewski@gmail.com, Kris

MRI is great. MRI is also hideously expensive. OCT is potentially a lot cheaper than MRI, with faster scanning, but it does have severe limitations as to the depth of objects it can sense. It's another tool in the arsenal, not a magic bullet.

well mri is 3D volume, not surface ! also 7T-mri can provide amazing detail with resolution : fraction of the millimeter in voxel size. anatomical scans do not require toxic fluids for contrast etc. and it is noninvasive and safe. bad sides : digestive and respiratory systems are notoriously hard in MRI, though SWIFT seems to mitigate the issue. real-time is challenging due to immense post-processing, though using GPU and distributed-cluster should be a viable option for MRI too.
