Fourier Neural Operator Networks: A Fast and General Solver for the Photoacoustic Wave Equation

no code implementations20 Aug 2021 Steven Guan, Ko-Tsung Hsu, Parag V. Chitnis

Simulation tools for photoacoustic wave propagation have played a key role in advancing photoacoustic imaging by providing quantitative and qualitative insights into parameters affecting image quality.

Dense Dilated UNet: Deep Learning for 3D Photoacoustic Tomography Image Reconstruction

no code implementations7 Apr 2021 Steven Guan, Ko-Tsung Hsu, Matthias Eyassu, Parag V. Chitnis

We compare the proposed CNN in terms of image quality as measured by the multiscale structural similarity index metric to the Fully Dense UNet (FD-UNet).
