LIMIS-Presentations at SPIE Photonics West 2023 in San Francisco
At the SPIE Photonics West 2023 in San Francisco, two PerfusiX-Imaging studies were presented. In the invited talk “Clinical Translation of a Novel, Dye-Free Perfusion Imaging Technique in Minimally Invasive Surgery” by dr. Wido Heeman, an overview of the development of the new medical device was presented. The opening talk of the “Endogenous and label-free imaging” session touched upon the pre-clinical and clinical data that showed great potential in assisting surgeons with better substantiated clinical decision making. Also, since PerfusiX-imaging is a dye-free imaging technique, it opens new possibilities for more efficient perfusion imaging. It also eliminates risks associated with contrast agents. In the second talk at the congress, Tim Hoffman MD, presented data on the identification of gastric conduit perfusion deficits with PerfusiX-Imaging. Laparoscopic LSCI, integrated with the PerfusiX-imaging system, offers an objective assessment of blood flow within the gastric conduit. The motion-stabilized feature compensates for laparoscopic camera movement, providing surgeons with clear and steady real-time visualization of perfusion images. The PerfusiX-Imaging data is compared to the surgical eye and to indocyanine green fluorescence imaging. Tim presented some compelling cases where the watershed area as indicated with fluorescence imaging is changing significantly overtime, whereas the watershed area does not change with PerfusiX. This could be attributed to the fact that PerfusiX measures blood flow and fluorescence imaging measures the presence of a fluorescent dye in the blood. The presentations on dye-free perfusion imaging using PerfusiX-Imaging at SPIE Photonics West 2023 have demonstrated the potential of this innovative technique in improving perfusion imaging in minimally invasive surgery.
