Photoacoustics with coherent light

open access: yesPhotoacoustics, 2016
Since its introduction in the mid-nineties, photoacoustic imaging of biological tissue has been one of the fastest growing biomedical imaging modality, and its basic principles are now considered as well established.

Attenuation Models in Photoacoustics

open access: yes, 2012
First, we review existing attenuation models and discuss their causality properties, which we believe to be essential for algorithms for inversion with attenuated data. Then, we survey causality properties of common attenuation models.

Towards quantitative tissue absorption imaging by combining photoacoustics and acousto-optics [PDF]

open access: yes, 2012
We propose a strategy for quantitative photoacoustic mapping of chromophore concentrations that can be performed purely experimentally. We exploit the possibility of acousto-optic modulation using focused ultrasound, and the principle that photons follow

State-of-the-Art Approaches for Image Deconvolution Problems, including Modern Deep Learning Architectures

open access: yesMicromachines, 2021
In modern digital microscopy, deconvolution methods are widely used to eliminate a number of image defects and increase resolution. In this review, we have divided these methods into classical, deep learning-based, and optimization-based methods.

Ultrasound-Based Fluid-Structure Interaction Modeling of Abdominal Aortic Aneurysms Incorporating Pre-stress

open access: yesFrontiers in Physiology, 2021
Currently, the prediction of rupture risk in abdominal aortic aneurysms (AAAs) solely relies on maximum diameter. However, wall mechanics and hemodynamics have shown to provide better risk indicators.
