Perfusion Imaging via Advection-Diffusion

This is the official repository for our work on modeling perfusion imaging via advection-diffusion. This repository contains codes for simulating synthetic normal/abnormal brain advection-diffusion dataset, and modeling perfusion imaging from both optimization-based (PIANO) and deep-learning-based (YETI, SONATA) perspectives, as well as all the experiments in our papers:

Deep Decomposition for Stochastic Normal-Abnormal Transport - CVPR 2022 (Oral Presentation)

Discovering Hidden Physics Behind Transport Dynamics - CVPR 2021 (Oral Presentation)

Perfusion Imaging: An Advection Diffusion Approach - IEEE TMI

PIANO: Perfusion Imaging via Advection-Diffusion - MICCAI 2020 (Early Accept)
