Mesh density functions based on local bandwidth applied to moving mesh methods
Elliott S. Wise, Ben T. Cox, Bradley E. Treeby
Moving mesh methods provide an efficient way of solving partial differential equations for which large, localised variations in the solution necessitate locally dense spatial meshe…
Acoustic Wave Field Reconstruction from Compressed Measurements with Application in Photoacoustic Tomography
Marta M. Betcke, Ben T. Cox, Nam Huynh +3
We present a method for the recovery of compressively sensed acoustic fields using patterned, instead of point-by-point, detection. From a limited number of such compressed measure…
Quantitative photoacoustic tomography using forward and adjoint Monte Carlo models of radiance
Roman Hochuli, Samuel Powell, Simon Arridge +1
Forward and adjoint Monte Carlo (MC) models of radiance are proposed for use in model-based quantitative photoacoustic tomography. A 2D radiance MC model using a harmonic angular b…
Nonzero-sum stochastic differential games with impulse controls: a verification theorem with applications
René Aïd, Matteo Basei, Giorgia Callegaro +2
We consider a general nonzero-sum impulse game with two players. The main mathematical contribution of the paper is a verification theorem which provides, under some regularity con…
On the Adjoint Operator in Photoacoustic Tomography
Simon R. Arridge, Marta M. Betcke, Ben T. Cox +2
Photoacoustic Tomography (PAT) is an emerging biomedical "imaging from coupled physics" technique, in which the image contrast is due to optical absorption, but the information is…
