CONTRAST-ENHANCED ULTRASOUND IMAGING METHOD, ULTRASONIC IMAGING APPARATUS, AND STORAGE MEDIUM

摘要

Provided are a contrast-enhanced ultrasound imaging method, an ultrasonic imaging apparatus, and a storage medium. The method comprises: on the basis of a plurality of ultrasonic pulses, exciting an ultrasonic probe to transmit ultrasonic waves to a target medium including a contrast agent, in order to receive echos of the ultrasonic waves, and to acquire, on the basis of the echos of the ultrasonic waves, a plurality of groups of ultrasonic echo data, wherein at least one of the amplitudes, phases and frequencies of the plurality of ultrasonic pulses is different; performing contrast microbubble signal extraction on the plurality of groups of ultrasonic echo data to obtain data to be processed; performing singular value decomposition filtering on the data to be processed to obtain processed data; and obtaining a contrast image on the basis of the processed data. In the solution of the present application, singular value decomposition filtering is performed on the ultrasonic echo data including the microbubble signal, and data used for contrast imaging is processed in a non-frequency domain, such that the problem of band overlap occurring during frequency domain processing can be avoided, thereby further increasing the signal-to-noise ratio and the contrast-to-tissue ratio of the contrast image.
