Abstract

The invention discloses a kidney medical image contour line extraction system and method, and the system comprises an image collection device, a gray level conversion device, a shape processing device, and a contour line extraction device, which are in communication connection in sequence, and the image collection device is used for obtaining a CT image of a specific kidney; the gray level conversion device is used for carrying out binarization processing on the specific kidney CT image acquired by the image acquisition device to obtain a first processed image; the morphological processing device is used for sequentially carrying out closing operation and opening operation on the first processed image to obtain a second processed image; and the contour line extraction device is used for determining the image edge of the second processed image through a first-order differential algorithm so as to extract a medical image contour line of a specific kidney.

Description

technical field [0001] The invention relates to the technical field of medical image processing, in particular to a medical image extraction system. Background technique [0002] In recent years, renal CT images have become more and more widely used clinically, and have become one of the important means for doctors to conduct renal function, pathology and anatomy, and the determination of renal boundaries is a prerequisite for quantitative analysis. The automatic segmentation of renal CT sequences and the extraction of renal borders are of great help to reduce the workload of doctors and improve the speed and accuracy of diagnosis. [0003] For example, Chinese Patent Application Publication No. CN106108932A discloses a device and method for fully automatic kidney region-of-interest extraction, which initially divides the preliminary region of interest based on the level set C-V model algorithm, and extracts the suspected region of interest; The kidney body ratio parameters...
