An ultrasonic treatment device (100) and method, and a data processing device. The method comprises: generating an electric pulse signal having a specific pulse waveform, a preset depth and a preset number of focusing points; generating ultrasonic waves in a preset focusing range and a preset frequency range according to the electric pulse signal, and transmitting the ultrasonic waves to a specific functional area of the brain to intervene and treat a nervous system disease; performing analysis on a brain wave signal by collecting the brain wave signal of the specific functional area of the brain, and adjusting a parameter of the specific pulse waveform when the brain wave signal is abnormal, so that the brain wave signal is recovered to be normal. The brain nerve regulation effect can be achieved by means of the ultrasonic waves; the ultrasonic treatment effect is monitored in real time according to changes of the brain wave signals; parameters of the ultrasonic waves are fed back and adjusted; craniotomy is not needed; noninvasive treatment of the nervous system disease can be achieved, and the operation process is simple.
A: Disclosed is a transcranial doppler system based on an annular array probe, the transcranial doppler system comprising an annular array probe (100), a transcranial ultrasonic acquisition device (200) and an upper computer (300). The annular array probe (100) transmits an ultrasonic signal into a cranium and sends an echo signal from the ultrasonic signal to the transcranial ultrasonic acquisition device (200); the transcranial ultrasonic acquisition device (200) obtains cerebral blood flow data based on the echo signal and sends the cerebral blood flow data to the upper computer (300); and the upper computer (300) generates a cerebral blood flow spectrum image from the cerebral blood flow data. The annular array probe (100) of the system sends low-frequency pulse signals with different delays into the cranium, such that the low-frequency pulse signals with different delays are focused at a preset depth therein, and the echo signal is received by means of focusing, thus enhancing the echo signal and improving the definition of the cerebral blood flow spectrum image and the detection rate.
B: A transcranial three-dimensional cerebral blood vessel imaging method: utilizing an automatically scannable annular array probe to send ultrasonic signals that have different delays to different scan positions in the cranium, such that the ultrasonic signals that have different delays are focused on a plurality of preset depths in a beam axial direction so as to detect intracranial cerebral blood vessels by means of focusing the ultrasonic signals; digitally delaying and focusing echo signals of the received ultrasonic signals, such that the echo signals are enhanced so as to improve the spatial form, positional accuracy and signal strength of acquired information of the cerebral blood vessels and/or cerebral blood flow, thereby improving the definition and detection rate of three-dimensional cerebral blood vessels and/or cerebral blood flow images. In addition, the annular array probe (100) has the characteristics of fewer passages and a small volume, and may be worn on the head instead of a TCD monitoring probe, and may thereby achieve the three-dimensional scanning and monitoring of intracranial cerebral blood vessels. Also disclosed is a transcranial three-dimensional cerebral blood vessel imaging system.
C: A sleep intervention method for improving sleep quality, comprising collecting brain waves generated by a human brain and performing a signal processing thereon (100); comparing the collected brain waves with a pre-stored brain wave template, determining whether a human body enters a corresponding sleep stage (101); recording, if the human body enters the corresponding sleep stage, the current brain wave signal (102); issuing, if the human body does not enter the corresponding sleep stage, a sleep inducing signal to induce the human body to enter the corresponding sleep stage, adjusting same, in real time, until the human body enters the corresponding sleep stage, and recording the current sleep inducing signal (103). The method improves the sleep condition of the human body.
D: An immune system regulation method and an ultrasonic immunotherapy device. The immune system regulation method comprises the steps of generating ultrasonic waves of specific parameters, transmitting same to a target human body tissue and organ, performing activation or suppression, etc. Also provided is a device structure for implementing immune system regulation. For different immune nervous systems, specific ultrasonic waves are generated and directed onto the nerve nuclei of a target nervous system to stimulate a central or peripheral system, so as to produce an activation or suppression immune effect, thereby achieving the purpose of immunotherapy of diseases.
