Photo-Acoustic Imaging in GI Surgery

Gastroenterologists commonly use image processing and scanning for minimally invasive diagnostics and treatment of chronic inflammatory diseases of the gastrointestinal tract and related organs and cancers. The new advances in gastroenterological photo-acoustics reflect a mixture of multispectral and multi-scale photo-acoustic (PA), ultrasound (US) and near-infrared (NIR) fluorescence imaging. Fully, optical front-facing probe or side-facing probe without contact with ultrasound (esophagus and colon). Deep Tissue P. A. Tomography was used in the pre-screening of selective contrast agents (pancreatic cancer) using experimental set-ups on the table. Previous live human tissue clinical trials have been undertaken on endoscopic mucosal resection tissue with PA-US tomography and pancreatic intraoperative PA and NIR multimodality fluorescence imaging. His new PA methods are very successful in early cancer screening.
