Deep-learning Image Reconstruction for Real-time Photoacoustic System [article]

MinWoo Kim, Geng-Shi Jeng, Ivan Pelivanov, Matthew O'Donnell
2020 arXiv   pre-print
Standard reconstruction methods for PA imaging are based on solving an inverse problem using appropriate signal and system models.  ...  For handheld scanners, however, the ill-posed conditions of limited detection view and bandwidth yield low image contrast and severe structure loss in most instances.  ...  Additional image quality improvements were demonstrated using multichannel data as the network input (upgUNET).  ...

Edge-Enhanced Dual Discriminator Generative Adversarial Network for Fast MRI with Parallel Imaging Using Multi-view Information [article]

Jiahao Huang, Weiping Ding, Jun Lv, Jingwen Yang, Hao Dong, Javier Del Ser, Jun Xia, Tiaojuan Ren, Stephen Wong, Guang Yang
2021 arXiv   pre-print
One discriminator is used for holistic image reconstruction, whereas the other one is responsible for enhancing edge information.  ...  However, MRI suffers from an inherent slow data acquisition process because data is collected sequentially in k-space.  ...  All considered methods can restore image structure and edge information for low and medium noise levels (20-50%), with PIDD having strong advantages over PISD and nPIDD.  ...
