Abstract

The present invention provides a method for contrast-enhanced ultrasound imaging and a region detection and imaging method for contrast-enhanced images. The region detection method for contrast-enhanced images includes: acquiring tissue signals and contrast signals in the process of contrast-enhanced ultrasound imaging; Perform preprocessing respectively; compare the preprocessed tissue signal and contrast signal; segment the image formed after comparison processing into contrast agent action area, tissue residual action area and noise action area by means of threshold segmentation; contrast contrast image The corresponding positions on , are marked as contrast agent area, tissue residual area and noise area, respectively. On the one hand, the invention greatly improves the CTR of contrast-enhanced ultrasound images, which is beneficial to clinical observation; on the other hand, it enhances the signal of the contrast agent, so that the contrast dose injected during contrast-enhanced ultrasound can be greatly reduced, and the inspection cost is effectively reduced.

Description

technical field

[0001] The invention relates to ultrasound contrast imaging technology, in particular to an ultrasound contrast imaging method and a region detection and imaging method of contrast images. Background technique

[0002] Ultrasound imaging is currently a relatively mature non-invasive detection method. Compared with CT and MRI (Magnetic Resonance Imaging, Magnetic Resonance Imaging, Magnetic Resonance Imaging), ultrasonic diagnosis has the advantages of less radiation, low cost, and convenient operation, making ultrasonic diagnosis the primary clinical examination method.

[0003] Contrast-enhanced ultrasound is the use of contrast agents to enhance scattered echoes, which can effectively improve the resolution, sensitivity and specificity of ultrasound diagnosis. The core of contrast-enhanced ultrasound imaging technology is how to extract the echo component of the contrast agent in the echo signal and suppress the echo component of the tissue. At present, th...
