1. , based on ultrasonic brain stimulation or the regulate and control method of extensive face array element, it is characterized in that, the method comprises:

  • Step 1, sets up head three-dimensional digital model;

    Step 2, needs the position stimulating or regulate and control to arrange virtual sound source at brain, and utilizes this virtual sound source to launch ultrasound wave to surrounding;

    Step 3, sound field emulation is carried out based on described head three-dimensional digital model, simulate the ultrasound wave of described virtual sound source transmitting after brain tissue, skull, ultrasonic coupling apparatus, arrive parameters,acoustic during element position, and emulation obtains the voltage signal that ultrasonic transducer obtains after piezoelectricity conversion;

    Step 4, according to the described parameters,acoustic obtained and voltage signal, by time reversal, applies the voltage of corresponding described voltage signal, launches ultrasound wave to array element, realize ultrasound wave and focus on through the virtual sound source place of skull in brain, carry out ultrasonic brain stimulation or regulation and control.
