Embodiment Construction

[0034] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0035] figure 1 is a logical block diagram showing an image processing system according to an exemplary embodiment of the present invention.

[0036] refer to figure 1 , an image processing system according to an exemplary embodiment of the present invention includes an image acquirer 110 , a tumor detector 120 , a ridge detector 130 and a tumor segmenter 140 .

[0037] The image acquirer 110 is used for acquiring two-dimensional breast ultrasound images. The image acquirer 110 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.

[0038] The tumor detector 120 is used to detect a tumor region containing a breast tumor from the two-dimensional breast ultrasound image acquired / read by the image...

Abstract

The invention provides an image processing system and an image processing method. A breast image processing system includes an image capturing device, a tumor detector, a spine detector and a tumor splitter, wherein the image capturing device is used for capturing a two-dimensional ultrasound breast image; the tumor detector is used for detecting a tumor area with a breast tumor from the two-dimensional ultrasound breast image captured by the image capturing unit; the spine detector is used for detecting the spine information from the captured two-dimensional ultrasound breast image; the tumor splitter is used for splitting the breast tumor from the detected tumor area based on a level set; a level set function is created for the two-dimensional ultrasound breast image in a manner that the detected tumor area serves as an initial contour curve, and the level set evolution of the contour curve is limited iteratively according to the spine information detected by the spine detection unit, so that the energy function of the contour curve can be minimized.

Description

technical field [0001] The present application relates to an image processing system and image processing method for breast ultrasound images, in particular to a method of detecting ridge information from breast ultrasound images, and segmenting breast tumors from breast ultrasound images based on level sets. In tumor segmentation processing, An image processing technique to remove fatty and shadowed regions from breast ultrasound images using detected ridge information to constrain level set evolution. 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, comp...
