The present invention provides a pulsed Doppler ultra-high spectral resolution imaging processing method and processing system. The method includes: acquiring IQ signals corresponding to N sampling points respectively on each scan line; in a fast time direction, performing wall filtering processing to form an IQ signal wall filtering sequence; performing FFT on each sampling point in the IQ signal wall filtering sequence in a slow and a fast time direction, respectively, to obtain an energy distribution matrix at different frequency shifts; acquiring a velocity distribution matrix; and retrieving a velocity sequence for display, querying the velocity distribution matrix and the energy distribution matrix according to the velocity sequence, and acquiring an energy sequence corresponding to the velocity sequence for displaying a final spectrum. When a transmit signal bandwidth is wider or a scatterer velocity is faster, the velocity resolution is greatly guaranteed.

Embodiments of the present disclosure disclose a method and a device for adjusting ultrasonic cavitation intensity. The adjusting method includes: controlling to adjust a jcavitation coefficient according to an icavitation intensity value and a target cavitation intensity value, so as to calculate to obtain an (i+1)cavitation intensity value; and continuing to control to adjust a (j+1)cavitation coefficient according to the (i+1)cavitation intensity value and the target cavitation intensity value, so as to calculate to obtain an (i+2)cavitation intensity value if the absolute value of a difference between the (i+1)cavitation intensity value and the target cavitation intensity value is greater than a set threshold value, and ending the method when it is determined that the absolute value of the difference between the (i+1)cavitation intensity value and the target cavitation intensity value is less than or equal to the set threshold value.
