Problems solved by technology

[0004] The existing breast lesion detection and analysis algorithms usually analyze the four mammogram images of the patient (that is, the CC and MLO images of both breasts respectively), and give the lesion detection results on each image respectively, but they cannot The matching relationship between lesions is given, and the matching relationship of lesions is very important. It can more accurately locate the position of lesions in three-dimensional space, and it can also help doctors judge the attributes of lesions and give correct BI-RADS classification

Embodiment 1

[0051] figure 2 A schematic block diagram of a lesion matching method for breast images according to an embodiment of the present invention is shown.

[0052] Such as figure 2 As shown, according to the lesion matching method of breast images according to an embodiment of the present invention, this embodiment takes mammograms as an example to illustrate the inventive solution, and the method of the present invention is not limited to mammograms (including ordinary X-ray images) It can also be used for images obtained by medical imaging methods such as color Doppler ultrasound, CT, and nuclear magnetic resonance used in breast examination.

[0053] A lesion matching method for breast images, comprising the following steps:

[0054] S201: Acquire images of different viewing angles of the mammary gland images in the same detection, wherein the images of different viewing angles include craniocaudal (CC) images and medial-lateral oblique (MLO) images;

[0055] In mammography...

Embodiment 2

[0100] Such as Figure 9 As shown, Embodiment 2 of the present invention provides an image processing device, and the image processing device may be a computer program (including program code) running on a terminal. The image processing device can execute the breast image lesion matching method in Embodiment 1, which specifically includes:

[0101] An image acquisition unit, configured to acquire images of different angles of view of the mammogram in the same detection, the images of different angles of view include craniocaudal (CC) images and medial-lateral oblique (MLO) images;

[0102] The lesion acquiring unit is configured to acquire the first lesion and the corresponding lesion information in the craniocaudal image, and acquire the second lesion and the corresponding lesion information in the medial-lateral oblique image, wherein the lesion information includes: lesion position, lesion size , lesion category and lesion probability;

[0103] A mask image generating uni...

Embodiment 3

[0111] as attached Figure 10 The third embodiment of the present invention provides an electronic device, which is characterized in that it includes: a processor and a memory; the processor is connected to the memory, wherein the memory is used to store computer programs, and the processor is used to call The computer program is used to execute the breast image lesion matching method described in the first embodiment.

[0112] Electronic equipment in this embodiment may include but not limited to mobile phones, notebook computers, digital broadcast receivers, PDA (personal digital assistants), PAD (tablet computers), PMP (portable multimedia players), vehicle-mounted terminals (such as vehicle-mounted mobile terminals such as navigation terminals) and stationary terminals such as digital TVs, desktop computers, medical image acquisition devices, and the like. Figure 10 The illustrated terminal device is only an example, and should not limit the functions and application sco...

Abstract

In view of the fact that the existing breast lesion detection algorithm can only detect lesions on a single image, and cannot give the corresponding relationship between the lesions on the two perspectives of the same breast, the present invention proposes a breast lesion matching method that includes multiple links. The lesions detected from different angles of view on the breast give a matching relationship, which is conducive to more accurately judging the type and attribute of lesions and eliminating some false positive lesions to a certain extent.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method for matching lesion parts in mammary gland images with different viewing angles. Background technique [0002] Breast cancer is the malignant tumor with the highest incidence rate in women. There are more than 270,000 new breast cancer cases in my country every year, and the incidence of breast cancer is increasing year by year, seriously threatening women's health. Early diagnosis of breast cancer is very important, early accurate diagnosis can increase the 5-year survival rate of breast cancer patients from 25% to 99%. Screening mammography is considered the test of choice for breast cancer screening. At present, mammography relies on subjective diagnosis, and the overall accuracy rate is not high enough and is limited by the level of evaluators. Compared with the personal experience judgment of a medical expert, the artificial intelligence recognition algorithm may i...
