摘要： This disclosure describes systems and methods for ultrasound imaging and targeting. In one example, the systems and methods improve targeting and imaging through a heterogenous medium by using the angular spectrum approach (ASA) alone or in combination with passive acoustic mapping (PAM). In another example, the systems and methods improve the ultrasound imaging of vessels using microbubbles. The imaging of the vessels is also aided by the ASA and PAM. A closed loop controller is described that adjusts the ultrasound pressure provided to a region of interest to a desired pressure based at least in part on the harmonic, ultra-harmonic, sub-harmonic, or broadband frequency ranges for the microbubbles.
