Problems solved by technology

SNR is determined by the sensitivity of the probe and the system platform. A high SNR means that smaller microbubbles can be detected, and the smaller the microbubbles, the smaller the signal amplitude. The signal amplitude of some small microbubbles is equivalent to

Embodiment Construction

[0041] The present invention will be further described in detail with reference to the drawings in the following specific embodiments.

[0042] such as Figure 1 As shown, the contrast-enhanced ultrasound imaging device includes a probe 10, a front signal processing module 13, a first signal processing module 16, a second signal processing module 17, a tissue image generation module 18, a contrast-enhanced image generation module 19, a contrast-enhanced ultrasound image enhancement system 20 and a display module 100.

[0043] The probe 10 is used to transmit ultrasonic waves to the human tissue 11 and receive ultrasonic echoes reflected by the tissue 11, and the ultrasonic echoes can be stored in the signal receiving module 12.

[0044] The pre-signal processing module 13 is used to process the ultrasonic echo signal and extract useful information. The pre-signal processing module 13 mainly includes amplifiers, beam combiners and filters to extract more useful signals with differen...

Abstract

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.

Description

Technical field [0001] The invention relates to contrast-enhanced ultrasound imaging equipment, in particular to a method and a system for enhancing contrast-enhanced ultrasound images. technical background [0002] Compared with conventional ultrasound imaging, contrast-enhanced ultrasound imaging can enhance the intensity of ultrasonic echo signal and show the tiny blood vessels that cannot be seen by conventional ultrasound. With the increasing requirements of clinical ultrasound examination, contrast-enhanced ultrasound imaging is more and more used in clinic, and it is more and more widely used to examine organs, and its position in clinical diagnosis is getting higher and higher. [0003] Contrast-enhanced ultrasound imaging is a kind of enhanced ultrasound imaging after injection of contrast agent, and contrast agent is an enhancer that can enhance the intensity of ultrasonic echo signal. There are many kinds of ultrasound contrast agents, and the most commonly used one is...
