Toward Real-Time Giga-Voxel Optoacoustic/Photoacoustic Microscopy: GPU-Accelerated Fourier Reconstruction with Quasi-3D Implementation

We propose a GPU-accelerated implementation of frequency-domain synthetic aperture focusing technique (SAFT) employing truncated regularized inverse k-space interpolation. Our achieves sub-1s reconstruction time for data sizes up to 100 M voxels, providing more than tenfold decrease in as compared CPU-based SAFT. provide an empirical model that can be used predict the execution quasi-3D any size given specifications computing system.
