Advanced Imaging Techniques for Plaque Risk Assessment

Cutting-edge imaging methods, such as combining light and ultrasound in photoacoustic imaging, trained neural networks for classification and risk assessment, and ultrasound for tissue composition analysis are key aspects discussed in the Innovation Workshop related to CVENT and H2020 project on February 3, 2017, Brussels. The focus is on risk assessment of plaque rupture, classification, and tissue composition of the plaque, utilizing innovative technologies for improved diagnosis and treatment decisions.
