A kind of ultrasonic imaging method and ultrasonic imaging equipment

Abstract

The invention discloses an ultrasonic imaging method and an ultrasonic imaging device and belongs to the field of medical diagnostic imaging. The ultrasonic imaging device, within each emitting period, is capable of continuously emitting two strings of reversely-complementary pulses at intervals of recognizable received echo, namely, in the pulse strings emitted each time, the two complementary pulse wave groups are fused and transmitted in single emission by means of follow-up emission at intervals of recognizable received echo, and the pulse waves are emitted and received twice at the premise of not downsizing the imaging frame frequency; echo signals are processed at a receiver according to the imaging need, so that echo signal signal-to-noise ratio is increased, image dynamic range iswidened, and the influence on imaging from sidelobes is relieved; therefore, the effect of the prior art employing multiple emissions is achieved. The problem is solved that existing ultrasonic equipment experience greatly decrease in imaging frame frequency during imaging; the imaging frame frequency can be increased, ultrasonic imaging speed can be increased, and the clinical application range of the ultrasonic imaging device is widened.
