Ultrasound deep brain stimulation method and system

An ultrasound deep brain stimulation method, comprising:

• medically imaging a head of an animal or a human being, to generate image data;
• creating a head 3D digital model according to the image data;
• inputting the head 3D digital model to a 3D printer to generate an ultrasound transmitting sequence;
• controlling the ultrasound transducer array to transmit ultrasound waves in accordance with the ultrasound transmitting sequence, to implement ultrasound deep brain stimulation to the brain nucleus to be stimulated.

An ultrasound deep brain stimulation system, comprising:

• a medical imaging equipment, an MM system, an ultrasound transmitting/receiving control system, a host control computer, an MM control system and a power management system;
• the host control computer is connected to the medical imaging equipment, the ultrasound transmitting/receiving control system and the MRI control system;
• the MRI system is connected to the MM control system;
• the MRI system is provided therein with an ultrasound transducer array, a head fixing and locating device, wherein the head fixing and locating device is used for fixing the head, the ultrasound transducer array is disposed around the head fixing and locating device and is connected to the ultrasound transmitting/receiving control system;
• the medical imaging equipment is used for photographing a head image, and reconstructing a head 3D digital model according to the head image;
• the host control computer creates a 3D digital model of the ultrasound transducer array according to structure, density and acoustic parameter information of the ultrasound transducer array, and generates an ultrasound transmitting sequence according to the head 3D digital model and the 3D digital model of the ultrasound transducer array, and then sends an ultrasound deep brain stimulation instruction to the ultrasound transmitting/receiving control system;
• the ultrasound transmitting/receiving control system receives the ultrasound deep brain stimulation instruction, controls the ultrasound transducer array according to the ultrasound deep brain stimulation instruction to transmit ultrasound wave to the brain nucleus to be stimulated in accordance with the ultrasound transmitting sequence to implement ultrasound deep brain stimulation;
• the MRI control system controls the MM system to monitor actual position and shape of an ultrasound focusing point in real time, to adjust the ultrasound transmitting sequence according to frequency, pulse duration, pulse length, pulse repetition frequency and intensity.
