Optoacoustic imaging in gastroenterology [PDF]
Translational Biophotonics, 2019 AbstractImaging modalities are crucial for diagnosis and monitoring of various gastroenterological diseases. To overcome limitations in established imaging methods, to improve outcome and reduce invasive procedures alternate modalities are needed. Optoacoustic imaging (OAI), an emerging method in both preclinical and translational settings, offers ...
