Abstract
Systems and methods for high spatial and temporal resolution ultrasound imaging of microvessels in a subject are described. Ultrasound data are acquired from a region-of-interest in a subject who has been administered a microbubble contrast agent. The ultrasound data are acquired while the microbubbles are moving through, or otherwise present in, the region-of-interest. The region-of-interest may include, for instance, microvessels or other microvasculature in the subject. By imaging microbubbles, a cross-correlation map between each microbubble image and a point spread function of the system can be generated. Accumulation of power-based cross-correlation maps may then be used to generate a high-resolution high-contrast image of the microvasculature.
