Mutual convolution of dual modes to enhance passive acoustic mapping for high duty-cycle HIFU exposures monitoring

Passive acoustic mapping (PAM) has been developed for cavitation detection during high intensity focused ultrasound (HIFU) treatment. Recently, Gray, et al. [1] used two separate PAM frames, acquired from two perpendicular imaging arrays to mutually filter with each other, which demonstrated the spatial resolution could be better than 1 mm that broke through the fundamental physical limitation of ...
