Embodiment Construction

[0010] In order to better understand the technical solutions of the present invention, the implementation manners of the present invention will be further described below in conjunction with the accompanying drawings.

[0011] The steps of the present invention are as follows:

[0012] The first step is to calculate the fuzzy membership function. Note the launch focus f k The corresponding medical ultrasound image is I k , where 1≤k≤N, N is the total number of emission focal points. Remember I k The gray level of the pixel at the middle height x, width y position is I k (x, y). Compute the launch focus f k Medical Ultrasound Image I k fuzzy membership function.

[0013] W ( x , f k ) = e - ( x - ...

Abstract

The present invention relates to a multifocus medical ultrasonic images connection method, belonging to the field of image processing technology. Said connection method includes the following steps: firstly, for pixels of every medical ultrasonic image collected by several emission focuses calculating its fuzzy membership grade, said fuzzy membership grade is the function of image emission focus and pixel positions; then utilizing fuzzy membership grade to make weighted combination of several images collected by different emission focuses so as to obtain result image.

Description

technical field [0001] The invention belongs to the technical field of image processing, in particular to a method for connecting multi-focus medical ultrasound images. Background technique [0002] In order to improve the local resolution of the resulting image, the medical ultrasound imaging system adopts a multi-focus transmission method, first obtains ultrasonic images at different focal points, and then connects the images obtained by these different focal points into one resulting image. The connection method of multi-focus medical ultrasound images usually adopts the method of connecting each piece of medical ultrasound images in segments. This method is simple to implement, but there are often obvious connection gaps between the images in the resulting image, which affects the quality of the resulting image. . [0003] In order to solve the problem that the traditional set theory cannot describe the fuzziness, imprecision and gradient characteristics that are ubiqui...
