An elasticity comparative measuring method includes: controlling an ultrasound probe to transmit a first ultrasound wave to a region of interest in a biological tissue when the biological tissue is deformed； receiving echoes of the first ultrasound wave to obtain a first echo signal； controlling the ultrasound probe to transmit a second ultrasound wave to the region of interest when the biological tissue is deformed； receiving echoes of the second ultrasound wave to obtain a second echo signal； obtaining a first elasticity result corresponding to a first cross section in the region of interest according to the first echo signal； obtaining a second elasticity result corresponding to a second cross section in the region of interest according to the second echo signal； outputting, via a display, the first elasticity result and the second elasticity result.
