| Zusammenfassung: | The invention discloses a power spectrum based ultrasonic scattering particle diameter imaging method. Based on ultrasonic radio frequency signals, the method calculates a power spectrum, calculates an ultrasonic scattering particle diameter parameters and calculates an ultrasonic scattering particle diameter parameter image. The method is as below: sliding a sliding window over an ultrasonic RF signal; calculating ultrasonic scattering particle parameters in each sliding window based on the power spectrum to obtain a matrix of ultrasonic scattering particle parameter values; interpolating thematrix of the ultrasonic scattering sub-parameter values into the size of the ultrasonic RF signal; and performing color mapping to obtain an ultrasound scattering particle diameter parameter image.The ultrasonic scattering particle diameter imaging method of the present invention can be used for ultrasonic tissue characterization of biological tissues such as mammary gland, liver and the like.
