A method and system for ultrasonic non-invasive transcranial imaging employing broadband acoustic metamaterial The method comprises: acquiring reflected signals corresponding to integral units formed of respective different acoustic metamaterial parameter combinations and the skull (S101); determining an acoustic metamaterial parameter combination to be determined according to a reflected signal to be determined and a trained three-layer BP neural network (S102); determining whether the acoustic metamaterial parameter combination is within a threshold space (S103); if so, using the determined acoustic metamaterial parameter combination to prepare acoustic metamaterial (S104); performing ultrasonic non-invasive transcranial imaging of a resolution mold (S105); and if not, performing re-determination (S106). The method and system for ultrasonic non-invasive transcranial imaging enhance the penetrability of acoustic waves passing through the skull to realize ultrasonic non-invasive transcranial imaging.
