Abstract

An FPGA-based space compound imaging method and device. The method comprises: acquiring ultrasonic non-space compound image data at different deflection angles (S101); carrying out interleaving processing on the ultrasonic non-space compound image data (S102); correcting the coordinates of the ultrasonic non-space compound image data, which has undergone interleaving processing, so as to recover image data subjected to angle deflection to image data with zero angle deflection (S103); carrying out de-interleaving processing on the image data, the coordinates thereof having been corrected (S104); and superposing pixel points corresponding to the de-interleaved ultrasonic non-space compound image data with different deflection angles, and generating a space compound image (S105). The present invention reduces the complexity of implementing a space compound algorithm, can effectively improve a space compound calculation speed, reduces the processing time for an image, and improves an imaging frame rate.

Description

technical field [0001] The invention relates to the technical field of medical ultrasonic imaging, in particular to an FPGA-based spatial compound imaging method and device. Background technique [0002] The spatial composite imaging in the medical ultrasound imaging system is an imaging method that scans the scanning object along different angles, and then superimposes the corresponding pixel points of the images of these different angles to form an image. Spatial compound imaging technology can improve the detailed performance of images, reduce the influence of speckle noise, clutter and other ultrasonic artifacts on image quality, enhance the resolution ability between tissues, and significantly improve the low-contrast tissues and tissues in ultrasonic images. The definition of small lesions clearly shows the boundaries between tissues. [0003] The existing spatial compound imaging technology scans the target tissue from different angles through the deflection of the s...
