Multispectral Optoacoustic Tomography for Rheumatoid Arthritis [PDF]

open access: yes, 2019
Aim of this study was to investigate the potential of multispectral optoacoustic tomography (MSOT) to detect and assess rheumatoid arthritis (RA) in a murine model. MSOT using inflammation targeting contrast agents allowed for detection and staging of RA through accurate visualization of arthritic inflammation, as confirmed by magnetic resonance ...

Multispectral optoacoustic tomography (MSOT) scanner for whole-body small animal imaging

open access: yesOptics Express, 2009
A major difficulty arising from whole-body optoacoustic imaging is the long acquisition times associated with recording signals from multiple spatial projections. The acquired signals are also generally weak and the signal-to-noise-ratio is low, problems often solved by signal averaging, which complicates acquisition and increases acquisition times to ...

High-speed widefield photoacoustic microscopy of small-animal hemodynamics [PDF]

open access: yes, 2018
Optical-resolution photoacoustic microscopy (OR-PAM) has become a popular tool in small-animal hemodynamic studies. However, previous OR-PAM techniques variously lacked a high imaging speed and/or a large field of view, impeding the study of highly ...

Artifacts in incomplete data tomography - with applications to photoacoustic tomography and sonar

open access: yes, 2015
We develop a paradigm using microlocal analysis that allows one to characterize the visible and added singularities in a broad range of incomplete data tomography problems.

Functional Imaging with Multispectral Optoacoustic Tomography: Methods and Applications [PDF]

open access: yes, 2022
This work advances functional imaging with multispectral optoacoustic tomography (MSOT) in two aspects: methodological, by developing and improving the methods for accurate quantification of blood oxygen saturation (sO2); and translational, by using MSOT for functional brain imaging. For sO2 quantification, Eigenspectra MSOT algorithm is improved using
