A tutorial in photoacoustic microscopy and tomography signal processing methods

Multiscale photoacoustic microscopy and computed tomography.

Photoacoustic tomography (PAT) is probably the fastest growing biomedical imaging technology owing to its capability of high-resolution sensing of rich optical contrast in vivo at depths beyond the optical transport mean free path (~1 mm in the skin). Existing high-resolution optical imaging technologies, such as confocal microscopy and two-photon microscopy, have fundamentally impacted biomedi...

Bregman methods in quantitative photoacoustic tomography

The Bregman method is utilized to quantitatively improve the simultaneous reconstruction of absorption and scattering coefficients for both Jacobian-based and gradient-based methods in quantitative photoacoustic tomography with multiple optical excitations. It is the synergistic combination of Bregman method and the total-variation regularization in achieving the desired quantitative improvemen...

Introduction: Advances in Optical Coherence Tomography, Photoacoustic Imaging, and Microscopy

The editors introduce the Biomedical Optics Express feature issue, “Advances in Optical Coherence Tomography, Photoacoustic Imaging, and Microscopy,” which combines three technical areas from the 2010 Optical Society of America (OSA), Biomedical Optics (BIOMED) Topical Meeting held on 11–14 April in Miami, Florida, and includes contributions from conference attendees. © 2010 Optical Society of ...

Multimodal simultaneous photoacoustic tomography, optical resolution microscopy and OCT system

A novel combined photoacoustic tomography (PAT), optical resolution photoacoustic microscopy (ORPAM) and optical coherence tomography (OCT) instrument has been developed for imaging biological tissues. The system is based on the use of a Fabry-Perot (FP) polymer film ultrasound sensor. This is designed to be transparent to wavelengths between 590nm and 1200nm so that photoacoustic excitation la...
