Claim 19:
20. The method of claim 15, wherein, the quantitative parameter representing the ultrasound attenuation degree in the liver is obtained by fitting or comparing the gain-compensated second ultrasound echo signal based on a depth, the quantitative parameter representing the difference between ultrasound echoes from the liver and the another tissue is obtained by comparing the gain-compensated second ultrasound echo signals from the liver and the another tissue, and the quantitative parameter representing the ultrasound velocity in the liver is obtained by comparing signal-to-noise ratios or ultrasound image resolutions of the gain-compensated second ultrasound echo signals obtained at different ultrasound velocities.
