Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for contrast enhanced ultrasound quantification imaging are provided. One of the methods includes: obtaining, for each location in a region of interest, a time-dependent ultrasound signal with respect to the region of interest for a time period; setting, for the each location, a global threshold for the obtained time-dependent ultrasound signal; determining, for the each location, a relative time instant that the time-dependent ultrasound signal reaches the global threshold; and generating a structural image of the region of interest based at least on the determined relative time instant of the each location, wherein the generated structural image displays different time instants that ultrasound signals corresponding to different locations in the region of interest reach the global threshold.
