The invention provides an analysis system for Doppler ultrasound image includes: a capture device, a processing device, and an output device. The capture device obtains a plurality of Doppler ultrasound images. The processing device arranges the color value in each pixel of the images based on the time domain, and obtains a reference sequence through a referencing method, furthermore performs a clustering method to obtain a plurality of correlation coefficient values, then uses a clustering and noise reducing method to classify into a primary pulsatile signal, a secondary pulsatile signal, and a noise signal, finally annotates the primary pulsatile signal, a secondary pulsatile signal, and a noise signal with different color values, respectively. The output device displays a plurality of visualized pulsatile ultrasound images for visualization.

Clustering, noise reduction and visualization method for doppler ultrasound images

The invention provides an analysis method of ultrasound echo signals based on statistics of scatterer distributions. The beginning of steps, choosing an ultrasound echo signal as a center, and calculating the signal image values of all ultrasound echo signals within a window block in an ultrasound image data to obtain an ultrasound scatterer value. Then, choosing another ultrasound echo signal as the center to repeat the previous steps until all of ultrasound echo signals may be calculated. The interval between each of ultrasound echo signal is one point distance. Finally, to output an ultrasound scatterer mode image with all ultrasound scatterer values by utilizing color scale. The ultrasound scatterer mode image can assist doctor to confirm the relative region of lesion in a target organ.

The present invention provides an acceleration and enhancement methods for ultrasound scatterer structure visualization. The method includes: obtaining an ultrasonic image, calculating all values of the ultrasonic signal points in each mwindow centered at a nsignal point to obtain a plurality of original statistical values ax, obtaining a plurality of mstatistical values by averaging value of original statistical values in the same window, calculating a plurality of mweighting values based on the statistical values by different weighting formulas, multiplying each weighting value with the original statistical values corresponding to the various size of windows, summing up to obtain an ultrasound structure scatterer value of the nultrasonic signal point, and generating an ultrasound scatterer structure image based on a matrix of the ultrasound scatterer values. The present invention further combined interpolation method can reduce the computation time and retain the 80% accuracy.
