Constrained Inversion and Spectral Unmixing in Multispectral Optoacoustic Tomography [PDF]
IEEE Transactions on Medical Imaging, 2017 Accurate extraction of physical and biochemical parameters from optoacoustic images is often impeded due to the use of unrigorous inversion schemes, incomplete tomographic detection coverage, or other experimental factors that cannot be readily accounted for during the image acquisition and reconstruction process.

Application of multispectral optoacoustic tomography for lower limb musculoskeletal sports injuries in adults [PDF]
PhotoacousticsCompositional changes in relation to musculoskeletal injuries are difficult to measure non-invasively. This study aims to use non-invasive label-free imaging with Multispectral Optoacoustic Tomography (MSOT) to evaluate compositional changes with injury.

Detection of microspheres in vivo using multispectral optoacoustic tomography [PDF]
Biotechnic & Histochemistry, 2017 We introduce a new approach to detect individual microparticles that contain NIR fluorescent dye by multispectral optoacoustic tomography in the context of the hemoglobin-rich environment within murine liver. We encapsulated a near infrared (NIR) fluorescent dye within polystyrene microspheres, then injected them into the ileocolic vein, which drains ...

Unmixing Molecular Agents From Absorbing Tissue in Multispectral Optoacoustic Tomography
IEEE Transactions on Medical Imaging, 2014 Detection of intrinsic or extrinsically administered chromophores and photo-absorbing nanoparticles has been achieved by multi-spectral optoacoustic tomography (MSOT). The detection sensitivity of MSOT depends not only on the signal to noise ratio considerations, as in conventional optoacoustic (photoacoustic) tomography implementations, but also on ...

Multispectral optoacoustic tomography of benign parotid tumors in vivo: a prospective observational pilot study [PDF]
Scientific ReportsParotid lumps are a heterogeneous group of mainly benign but also malignant tumors. Preoperative imaging does not allow a differentiation between tumor types. Multispectral optoacoustic tomography (MSOT) may improve the preoperative diagnostics.

Croconaine-based nanoparticles enable efficient optoacoustic imaging of murine brain tumors
Photoacoustics, 2021 Contrast enhancement in optoacoustic (photoacoustic) imaging can be achieved with agents that exhibit high absorption cross-sections, high photostability, low quantum yield, low toxicity, and preferential bio-distribution and clearance profiles. Based on
