Problems solved by technology

In addition, affected by the directivity of the probe, the quality of the images obtained by scanning in different directions will be different. As the scanning angle increases, the signal-to-noise ratio of the image will decrease, and some artifacts will even occur.

Embodiment Construction

[0043] In the ultrasonic diagnostic system (hereinafter referred to as "system"), the deflection of the scanning line can be realized by controlling the scanning parameters of the transmitting and receiving channels, such as figure 2shown. Under the control of the multi-angle image fusion control unit, the scanning parameter generation unit sequentially generates scanning parameters in different scanning directions; in each scanning direction, the scanning control circuit uses the scanning parameters to control the emission and reception scanning; the scanning line forming module The channel data is combined to form a scan line; the digital signal processing module performs digital signal processing on each scan line to obtain the echo information of the object; the image generation module generates the deflection image of the object according to the echo information of the object, and the generated The deflection image is stored in the image memory; the angle images scanned ...

Abstract

The invention discloses a spatial compound imaging method and device and an ultrasonic imaging system. The spatial compound imaging method comprises the steps of generating a combination coefficient Coefx according to preset parameters; performing resampling on existing deflection image and converting the existing deflection image into a zero-angle image Ax(t) in a coordinate system; reading a result image C(t-1) of the previous spatial compound imaging; utilizing the combination coefficient Coefx to respectively perform multiplied weighting calculation on the result image C(t-1) of the previous spatial compound imaging and the zero-angle coordinate space image Ax(t) obtained through resampling of the existing deflection image to obtain a weighted compound image Coefx*C(t-1) and a weighted angle image (1-Coefx)* Ax(t), performing summation of the weighted compound image and the weighted angle image to obtain a result image C(t) of the existing spatial compound imaging. The multiple-angle spatial compounding is achieved by adopting frame correlation methods, and by combining spatial compounding and time compounding, boundaries caused by different-angle images are effectively inhibited, and image degradation caused by angle deflection is reduced.

Description

technical field [0001] The invention relates to a medical image processing technology, in particular to a spatial composite imaging method and device in an ultrasonic imaging system. Background technique [0002] Since the 1980s, with the development of ultrasonic imaging equipment and electronic technology, the quality of ultrasonic B-mode images has been greatly improved, and various scanning technologies, signal processing technologies, and image processing technologies have emerged. [0003] Multi-angle space composite technology is an effective way to improve the quality of B-type images by combining scanning technology, signal processing and image processing technology. This technology is different from pure image processing. It performs multi-angle scanning and receiving at the front end, performs signal processing on images from different angles to obtain an ultrasound image, and then performs data fusion on images from different angles in the image processing link t...
