Abstract

The invention provides a planar ultrasonic imaging processing method and device based on virtual multi-angle composition at a receiving end, and aims to solve the problem that frame frequency and precision of single planar ultrasonic waves cannot meet the demand simultaneously in the prior art. According to the planar ultrasonic imaging processing method, received first echo data is subjected to virtual delaying, second echo data of receiving planes at different angles are obtained, and the second echo data of the receiving plane at each angle is subjected to beam forming according to the delay superposition principle, so that an image of the receiving plane at each angle is obtained; the images of the receiving planes at different angles are superposed, and a final image of the single planar ultrasonic waves is obtained. According to the single planar ultrasonic imaging processing method in the embodiment, single-pass planar wave emitting image quality is improved, planar wave emitting times are reduced, so that imaging frame frequency of the system is improved, and the method is compatible with a conventional method.

Description

technical field [0001] The invention belongs to the field of ultrasonic imaging and data processing, and in particular relates to a plane wave imaging processing method and device based on virtual multi-angle compounding at a receiving end. Background technique [0002] With the continuous development of medicine, ultrasound imaging has become a commonly used observation method in medicine. Ultrasound imaging uses ultrasonic beams to scan the human body, and obtains state information of internal organs by receiving reflected signals of ultrasonic beams. The processing of the reflected signal largely determines the quality of the obtained image. [0003] The traditional ultrasound imaging mode is focused wave imaging, which usually emits a series of focused waves in different directions, and each focused wave obtains a column of images. A high-precision ultrasound image requires a sufficient number of shots, thus limiting the frame rate of the image. Different from the tra...
