摘要： There is provided a method of processing an ultrasound spectrum image. According to such method, a spectrum image is formed based on ultrasound data and then the noise is removed from the spectrum image. The noise-removed spectrum image is matched with one or more spectrum models representing specific spectrum types. Then, whether or not the noise-removed spectrum image contains an aliasing is checked. If the noise-removed spectrum image contains the aliasing, then the aliasing is removed from the noise-removed spectrum image to provide a noise-removed spectrum image without the aliasing. Thereafter, contour tracing is performed on the noise-removed spectrum image without the aliasing to detect contour points. Further, peak tracing is performed on the noise-removed spectrum image without the aliasing to detect peaks.

摘要： An ultrasound diagnostic system and a method for the same update a pulse repetition frequency(PRF) by sensing an aliasing of a sampled data. A sample data generator generates sample data by transmitting an ultrasound signal into a human body and sampling a reflected signal of the ultrasound signal. A frequency distribution data generator generates a frequency distribution data by processing the sample data. A blood flow velocity detector determines a blood flow velocity on the basis of the frequency distribution data. An aliasing detector detects whether or not an aliasing occurs in the frequency distribution data. The aliasing detector computes a peak index corresponding to the fastest blood flow velocity component among the frequency components comprising the frequency distribution data, selects a frequency range having the largest sum of power levels of the frequency components between a positive frequency range and a negative frequency range, compares the selected frequency range with the peak index, and determines whether an aliasing occurs or not.
