Zusammenfassung: | The invention provides a cavitation micro-bubble high signal-to-noise ratio ultrasonic rapidly imaging and dynamic dimension distribution estimating method, comprising: (1) building a cavitation micro bubble wavelet under a static state starting condition; (2) acquiring information of backscatter Intensity change along time in a solution and in a source energy irradiation volume by a full-digitization ultrasonic two dimension planar-array energy transducer and by a plane wave emission and reception manner, and carrying out micro bubble wavelet transformation on it to raise cavitation micro bubble imaging signal-to-noise ratio; (3) acquiring a radius of micro bubble with a maximum number in a cavitation micro bubble group; (4) dividing a cavitation micro bubble area into sub-areas with a same size, to obtain brightness corresponding to the micro bubble with the maximum number in each sub-area, thereby obtaining dimension distribution of the whole cavitation micro bubble group; and (5) obtaining volume distribu |
