Multispectral optoacoustic tomography by means of normalized spectral ratio

Optics Letters, 2011
Quantification of biomarkers using multispectral optoacoustic tomography can be challenging due to photon fluence variations with depth and spatially heterogeneous tissue optical properties. Herein we introduce a spectral ratio approach that accounts for photon fluence variations.

Application of multispectral optoacoustic tomography for lower limb musculoskeletal sports injuries in adults [PDF]

Photoacoustics
Compositional 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.

Sensitivity of molecular target detection by multispectral optoacoustic tomography (MSOT)

Medical Physics, 2009
Optoacoustic imaging is emerging as a noninvasive imaging modality that can resolve optical contrast through several millimeters to centimeters of tissue with the resolution achieved by ultrasound imaging. More recently, applied at multiple illumination wavelengths, multispectral optoacoustic tomography (MSOT) offered the ability to effectively ...

Compressed system models in multispectral optoacoustic tomography

2015 IEEE 12th International Symposium on Biomedical Imaging (ISBI), 2015
One of the challenges of multispectral optoacoustic tomography (MSOT) is the reconstruction of the images from the projection data. Conventionally, analytical inversion formulae are used owing to their simplicity and numerical efficiency. However, such solutions are often limited to ideal detection scenarios and lead to image artifacts when the system ...
