Exploiting flow dynamics for super-resolution in contrast-enhanced ultrasound

Understand

Ultrasound localization microscopy offers new radiation-free diagnostic tools for vascular imaging deep within the tissue.

• Sequential localization of echoes returned from inert microbubbles with low-concentration within the bloodstream reveal the vasculature with capillary resolution.
• Despite its high spatial resolution, low microbubble concentrations dictate the acquisition of tens of thousands of images, over the course of several seconds to tens of seconds, to produce a single super-resolved image.
• %since each echo is required to be well separated from adjacent microbubbles.
