Ultrasound imaging methods and devices

Abstract

This application provides an ultrasound imaging method and apparatus, which emits a mixed sequence of ultrasound waves including a first sequence of ultrasound waves and a second sequence of ultrasound waves. The first sequence of ultrasound waves is used to detect the motion velocity of a target tissue and calculate the motion velocity of the target tissue at each beam combining point. The second sequence of ultrasound waves is used to image the target tissue. The motion velocity of the target tissue at each beam combining point is calculated based on the first sequence of ultrasound waves. Then, the beam combining data at each beam combining point of the second sequence of ultrasound waves is compensated, or the beam combining parameters at each beam combining point of the second sequence of ultrasound waves are determined, or the number of times the second sequence of ultrasound waves is combined is determined. Finally, combined imaging is performed. In this way, ultrasound imaging is directly or indirectly compensated based on the motion velocity of the target tissue, thereby improving the imaging effect.
