Embodiment Construction
[0046] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0047] figure 1 is a schematic diagram showing a logical block diagram of an image processing system according to an exemplary embodiment of the present invention and its execution of image processing.
[0048] refer to figure 1 , the image processing system includes an image collector 100 , a tumor detector 110 , a multi-parameter segmenter 120 , a feature scorer 140 and a fusion unit 150 .
[0049] The image collector 100 acquires two-dimensional breast ultrasound images (such as figure 1 source image shown on the lower side of the image grabber in the middle). The image collector 100 can acquire the two-dimensional breast ultrasound image from an ultrasound imaging device connected thereto, and can also read the two-dimensional breast ultrasound image from an information storage medium. According to a preferred embodiment of the present inv...

An image processing system for breast images includes: an image collector for acquiring two-dimensional breast ultrasound images; a tumor detector for detecting M interest regions containing breast tumors from the acquired two-dimensional breast ultrasound images, and Scoring each region of interest as its detection score, wherein M>0; a multi-parameter segmenter for segmenting K candidate tumor contours from each of the M regions of interest using K tumor segmentation algorithms respectively, And record the detection score for each candidate tumor contour, wherein K>0; the feature scorer is used to evaluate and score each candidate tumor contour according to at least one predetermined feature; the fusion device is used to evaluate and score each candidate tumor contour according to the M*K The detection scores and feature scores of candidate tumor contours, and the final segmented tumor contour is selected from the M*K candidate tumor contours.
Description
technical field [0001] This application relates to an image processing system for breast ultrasound images, in particular to a method of detecting and scoring multiple breast tumor interest regions from breast breast ultrasound images, and using a multi-parameter multiple tumor segmentation method for each interest region Segmentation processing and scoring, and an image processing technology that selects a segmentation result with a higher comprehensive index from multiple segmentation results. Background technique [0002] Breast cancer is the second leading killer of women, and early detection is the key to reducing the mortality rate (40% or more). Ultrasound is increasingly being used in breast imaging as a complementary diagnostic test to mammography (X-rays), when reduced sensitivity of mammography may occur or when there are unacceptable radiation risks associated with mammography, It is also used by itself as a first-line imaging technique. Therefore, computer-aid...
