Abstract

The invention discloses a space compound imaging method and device based on an FPGA, and the method comprises the steps: obtaining supersonic non-space compound image data at different deflection angles; carrying out the interlacing processing of the supersonic non-space compound image data; carrying out the coordinate coordination of the supersonic non-space compound image data after interlacing processing, so as to enable the image data to which angle deflection happens to be recovered to the image data with zero angle deflection; carrying out the de-interlacing processing of the image data after coordinate correction; carrying out the superposing of pixels corresponding to the supersonic non-space compound image data with different deflection angles after de-interlacing, and generating a space compound image. The method reduces the implementation complexity of a space compound algorithm, can effectively improve the space compound calculation speed, reduces the processing time of images, and improves the 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...
