Coronary flow assessment by 3D ultrafast ultrasound localization microscopy

Three-dimensional coronary ultrasound localization microscopy enables the visualization of the coronary vasculature in beating hearts at a scale down to microvascular structures (<20 μm resolution). This imaging technique provides unprecedented insights into the anatomy and function of coronary arteries at the microvasculature level. This new technology is highly translational and has the potential to become a major tool for the clinical investigation of the coronary microcirculation.

The real data (3D velocity vector field) were converted (Matlab) and imported in the 3D software (Houdini) and then rendered as an animation using the Redshift render engine. The particle's color was mapped to velocity direction (down/orange and up/blue).
