Embodiment approach

[0169] As an implementable manner, the calculation formula for merging the current frame and the previous frame is as follows:

[0170] The edge pixel matrix of the fused intermediate image is:

[0171]

[0172] Among them, BE k '(i, j) is the edge pixel matrix of the fused intermediate image, BE k (i, j) is the edge pixel matrix of the current frame, BE k-1 (i, j) is the edge pixel point matrix of the previous frame;

[0173] The pixel value matrix of the fused intermediate image is:

[0174]

[0175] Among them, D k '(i, j) is the pixel value matrix of the intermediate image, D k (i, j) is the pixel value matrix of the current frame, D k-1 (i, j) is the pixel value matrix of the previous frame.

[0176] Step S500, setting the edge pixel point matrix and pixel value matrix of the current frame as the edge pixel point matrix and pixel value matrix of the intermediate image, namely D k '=D k , BE k '=BE k , execute step S600.

[0177] Step S600 , according to ...

Abstract

The invention provides a frame-based ultrasound image processing method and a frame-based ultrasound image processing system. The method comprises the following steps: step A, acquiring image frame information, and calculating superposition measurement between the current frame and the former frame by edge pixel point matrixes of the current frame and the former frame; step B, according to the calculated superposition measurement, judging whether the current frame is related to the former frame, if yes, executing step C, and if not, executing step D; step C, fusing the current frame and the former frame to obtain an intermediate image, and executing step E; step D, setting the current frame as the intermediate image; step E, removing isolated edge pixel points, and performing edge enhancement transformation to obtain a novel image; and step F, outputting the novel image. According to the frame-based ultrasound image processing method and the frame-based ultrasound image processing system, with the combination of interframe related information, the information of former and later frames is fused, the edge of the fused image is subjected to enhancement transformation, and simultaneously, the speckle noise on the image out of the enhanced edge can be avoided.

Description

technical field [0001] The invention relates to the field of digital image processing, in particular to a frame-based ultrasonic image processing method and system. Background technique [0002] Ultrasound imaging, generally speaking, sends a group of ultrasonic waves along a known direction. When it encounters different acoustic reactance tissues, echoes are generated, and ultrasonic detection technology is used to form a two-dimensional image. Each of the two-dimensional images The dots correspond to the ultrasound reflection intensities at different positions of the illuminated object. In the process of ultrasonic image formation, when the ultrasonic wave length is comparable to the surface roughness of the irradiated object, speckle noise will be generated. The existence of speckle noise easily makes it very difficult to detect and enhance the edges of illuminated objects. Therefore, an image edge enhancement technology is needed to process the image. [0003] Typical...
