On Functional Activations in Deep Neural Networks

no code implementations17 Nov 2023 Andrew S. Nencka, L. Tugan Muftuler, Peter Laviolette, Kevin M. Koch

These networks were repeatable across repeated performance of related tasks, and correspondence of identified functional networks and activation in tasks not used to define the functional networks was shown to accurately identify the presented task.

Deep-learning based Tools for Automated Protocol Definition of Advanced Diagnostic Imaging Exams

no code implementations28 May 2021 Andrew S. Nencka, Mohammad Sherafati, Timothy Goebel, Parag Tolat, Kevin M. Koch

Results: The top predicted protocol in AP mode was correct for 82. 8%, 73. 8%, and 69. 3% of the test cases for "General", "ACR", and "Local" protocol classes, respectively.

Weakly-supervised Learning for Single-step Quantitative Susceptibility Mapping

no code implementations14 Aug 2020 Juan Liu, Kevin M. Koch

wTFI uses the BFR method RESHARP local fields as supervision to perform a multi-task learning of local tissue fields and QSM, and is capable of recovering magnetic susceptibility estimates near the edges of the brain where are eroded in RESHARP and realize whole brain QSM estimation.

Meta-QSM: An Image-Resolution-Arbitrary Network for QSM Reconstruction

no code implementations1 Aug 2019 Juan Liu, Kevin M. Koch

In this work, we proposed a novel method called Meta-QSM to firstly solve QSM reconstruction of arbitrary image resolution with a single model.

Non-locally Encoder-Decoder Convolutional Network for Whole Brain QSM Inversion

no code implementations11 Apr 2019 Juan Liu, Kevin M. Koch

Quantitative Susceptibility Mapping (QSM) reconstruction is a challenging inverse problem driven by ill conditioning of its field-to -susceptibility transformation.

MRI Tissue Magnetism Quantification through Total Field Inversion with Deep Neural Networks

no code implementations11 Apr 2019 Juan Liu, Kevin M. Koch

Quantitative susceptibility mapping (QSM) utilizes MRI signal phase to infer estimates of local tissue magnetism (magnetic susceptibility), which has been shown useful to provide novel image contrast and as biomarkers of abnormal tissue.
