Applying dynamic contrast enhanced MSOT imaging to intratumoral pharmacokinetic modeling
Photoacoustics, 2018 Examining the dynamics of an agent in the tumor microenvironment can offer critical insights to the influx rate and accumulation of the agent. Intratumoral kinetic characterization in the in vivo setting can further elicudate distribution patterns and ...

[Optoacoustic spectroscopy and imaging].
Zeitschrift fur medizinische Physik, 2002 Optoacoustic methods are based on the thermoelastic effect, according to which a short laser pulse is absorbed in a medium and generates an acoustic wave following rapid heating and thermal expansion. This study it sought to demonstrate how the optical properties and structure of the sample can be obtained from acoustic signals that are measured on the

Importance of Ultrawide Bandwidth for Optoacoustic Esophagus Imaging
IEEE Transactions on Medical Imaging, 2018 Optoacoustic (photoacoustic) endoscopy has shown potential to reveal complementary contrast to optical endoscopy methods, indicating clinical relevance. However operational parameters for accurate optoacoustic endoscopy must be specified for optimal performance.
