Journal ArticleDOI
Model-Based Learning for Accelerated, Limited-View 3-D Photoacoustic Tomography
Andreas Hauptmann,Felix Lucka,Marta M. Betcke,Nam Huynh,Jonas Adler,Ben T. Cox,Paul C. Beard,Sebastien Ourselin,Simon R. Arridge +8 more
TL;DR: A deep neural network is presented that is specifically designed to provide high resolution 3-D images from restricted photoacoustic measurements to represent an iterative scheme and incorporates gradient information of the data fit to compensate for limited view artifacts.
Journal ArticleDOI
Simulating Transcranial Direct Current Stimulation With a Detailed Anisotropic Human Head Model
Sumientra Rampersad,Arno M. Janssen,Felix Lucka,Umit Aydin,Benjamin Lanfer,Seok Lew,Carsten H. Wolters,Dick F. Stegeman,Thom F. Oostendorp +8 more
TL;DR: This study suggests that improvements in the effects of transcranial direct current stimulation are achievable and introduces new methods to evaluate the effectivity in the target area specifically, where it needs higher input currents than cerebral stimulation does.
Journal ArticleDOI
Real‐time cardiovascular MR with spatio‐temporal artifact suppression using deep learning–proof of concept in congenital heart disease
Andreas Hauptmann,Simon R. Arridge,Felix Lucka,Felix Lucka,Vivek Muthurangu,Jennifer A. Steeden +5 more
TL;DR: In this article, a 3D (2D plus time) CNN architecture was developed and trained using synthetic training data created from previously acquired breath hold cine images from 250 CHD patients.
Journal ArticleDOI
Accelerated high-resolution photoacoustic tomography via compressed sensing.
Simon R. Arridge,Paul C. Beard,Marta M. Betcke,Ben T. Cox,Nam Huynh,Felix Lucka,Olumide Ogunlade,Edward Z. Zhang +7 more
TL;DR: The results show that images with good spatial resolution and contrast can be obtained from highly sub-sampled PAT data if variational image reconstruction techniques that describe the tissues structures with suitable sparsity-constraints are used.
Journal ArticleDOI
On the adjoint operator in photoacoustic tomography
TL;DR: In this paper, a simple mathematical derivation of the adjoint of the photoacoustic tomography (PAT) forward operator in the continuous framework is presented, and an efficient numerical implementation of this adjoint using a k-space time domain wave propagation model is described and illustrated in the context of variational PAT image reconstruction, on both 2D and 3D examples including inhomogeneous sound speed.
