A sparse deep learning approach for automatic segmentation of human vasculature in multispectral optoacoustic tomography

Photoacoustics, 2020
Multispectral Optoacoustic Tomography (MSOT) resolves oxy- (HbO2) and deoxy-hemoglobin (Hb) to perform vascular imaging. MSOT suffers from gradual signal attenuation with depth due to light-tissue interactions: an effect that hinders the precise manual ...

Recurrent and convolutional neural networks for sequential multispectral optoacoustic tomography (MSOT) imaging

Journal of Biophotonics, 2023
AbstractMultispectral optoacoustic tomography (MSOT) is a beneficial technique for diagnosing and analyzing biological samples since it provides meticulous details in anatomy and physiology. However, acquiring high through‐plane resolution volumetric MSOT is time‐consuming.

Current and Emerging Clinical Applications of Multispectral Optoacoustic Tomography (MSOT) in Oncology [PDF]

Clinical Cancer Research, 2016
Abstract Accurate detection and characterization of cancers are key for providing timely intervention and effective treatments. Current imaging technologies are particularly limited when it comes to detecting very small tumors in vivo, i.e., very early cancers or metastases, differentiating viable tumor from surrounding dead tumor tissue,
