Contrast-enhanced ultrasound imaging method, system, control device and storage medium

Abstract

The present application discloses a contrast-enhanced ultrasound imaging method, including: sending at least one combination of excitation pulse sequences including multiple sets of excitation pulse sequences to an ultrasonic transmitting circuit; wherein, in each combination of excitation pulse sequences, the pulses of each group of excitation pulse sequences The amplitudes are not exactly the same; obtain the echo signals corresponding to each group of excitation pulse sequences; respectively calculate the characteristic values ​​of the contrast tissue ratio of each group of echo signals; the excitation pulse sequence corresponding to the characteristic value with the smallest difference from the preset ideal value determining the optimal excitation pulse sequence; sending the optimal excitation pulse sequence to the ultrasonic transmitting circuit, so as to generate image data based on the echo signal of the optimal excitation pulse sequence. The present application can effectively ensure the image quality of contrast-enhanced ultrasound imaging for any imaging target, greatly improving applicability and flexibility. The present application also discloses an ultrasound contrast imaging system, a control device, and a computer-readable storage medium, which also have the above beneficial effects.

Description

technical field [0001] The present application relates to the technical field of ultrasound imaging, and in particular to an ultrasound contrast imaging method, system, control device and computer-readable storage medium. Background technique [0002] Contrast-enhanced ultrasound imaging technology has been widely used in modern medical and health fields. It uses a certain form of pulse sequence to excite and emit ultrasonic waves to the area to be imaged, and uses the nonlinear characteristics of contrast agents (mostly suspensions containing microbubbles), based on The reflected echo signal is processed to realize imaging. Since the reflection signal of the biological tissue in the imaging background will affect the imaging effect, in ultrasound imaging, it is necessary to obtain the echo signal reflected by the contrast agent (i.e. the contrast signal) to the greatest extent, and to suppress the echo signal reflected by the biological tissue as much as possible. wave sig...

Problems solved by technology

However, the contrast-enhanced ultrasound imaging system in the prior art generally adopts a fixed pulse sequence, but different pathological characteristics of different patients have different ultrasonic manifestations, and a certain fixed pulse sequence cannot obtain ideal imaging effects on all patients. less flexible
