Description

Ultrasonic contrast imaging device

Technical Field

The utility model relates to an ultrasonic contrast imaging technical field particularly relates to an ultrasonic contrast imaging device.

Background

The ultrasonic wave meets the scatterer to generate scattering, and the scattering strength of the ultrasonic wave is related to the size and the shape of the scatterer and the acoustic impedance difference of surrounding tissues. Blood scatters ultrasound very weakly, so blood appears "anechoic" on common ultrasound instruments. If a medium (microbubbles) with an acoustic impedance distinct from that of blood is added to the blood, scattering within the blood is enhanced, which is the basic principle of acoustic contrast. The tissue ultrasonic contrast imaging is based on the principle that ultrasonic contrast agent, namely solution containing micro-bubbles, is injected into the body, and the contrast agent enters organs and tissues to develop or enhance the organs and tissues, thereby providing important basis for clinical diagnosis.

In recent years, ultrasound contrast imaging has played an increasingly important role in the differential diagnosis and ablation assessment of cardiovascular diseases, liver, thyroid and breast diseases, and the like. Generally, in order to distinguish such a hemodynamic difference between normal tissue and malignant lesion tissue, ultrasound contrast is required to have a certain imaging frame rate. The currently used frame rate for 2D real-time ultrasound contrast imaging is usually set to 10 frames per second (fps) to 15 fps. The high frame rate contrast technology can increase the contrast imaging frame rate to dozens or even hundreds of frames per second. Furthermore, super-resolution imaging techniques can render fine images beyond the half-wavelength limit of conventional ultrasound with contrast microbubbles, which are often acquired at higher frame rates using contrast data.
