摘要

A method and a system for enhancing ultrasound contrast images, and an ultrasound contrast imaging device; on the basis of non-linear contrast information and linear tissue information acquired from an ultrasound echo signal, calculating non-linear parameters to obtain a non-linear parameter distribution map, respectively using a bipolar threshold to divide the non-linear distribution map, each division separating out contrast agent regions (31, 33) and tissue residue regions (32, 34); implementing enhancement processing of the contrast agent regions (31, 33) and suppression processing of the tissue residue regions (32, 34), to thereby implement significant enhancement of the definite contrast agent regions (31, 33), and significant suppression of the definite tissue residue regions (32, 34), the extent of the enhancement and suppression of the regions between the contrast agent and residual tissue regions being weaker; finally merging two classified and weight adjusted results, such that the enhancement of the contrast agent, the suppression of the contrast agent, and the conservation processing of the regions between the contrast agent and the tissue residue all achieve ideal contrast image enhancement effects.
