Problems solved by technology

However, the fixed distance method does not consider individual differences at all, and often cannot achieve the ideal thickness equalization effect; while the model method is limited by the assumption of the model itself, and the thickness equalization effect that can be achieved is also limited

Abstract

Embodiments of the invention disclose a method and a device for processing mammary gland images, and a mammary gland imaging device. The method comprises: obtaining an original scanned image, according to the original scanned image, obtaining a low-frequency image and a high-frequency image; according to mammary gland width, mammary gland oppressed thickness, and gray level transformation distance, determining a model, determining a gray level transformation region of the low-frequency image; performing gray level transformation on the gray level transformation region, obtaining a target low-frequency image after thickness equilibrium, and reconstructing the target low-frequency image and the high-frequency image, to generate a target image. Through the above technical scheme, the gray level transformation region which needs thickness equilibrium in the mammary gland image is realized to be accurately and automatically obtained, so as to obtain a mammary gland image whose gray level distribution is more uniform, and achieve better mammary gland image thickness equalization effect.

Description

technical field [0001] Embodiments of the present invention relate to medical image processing technologies, and in particular to a breast image processing method, device, and breast imaging equipment. Background technique [0002] During the imaging process of full digital mammography, the breast is photographed when the compression plate is compressed. However, due to the fact that the compression plate cannot compress the edge of the mammary gland and the distribution characteristics of the mammary gland tissue, there is a large grayscale difference between the central area and the peripheral area of ​​the mammary gland image obtained by shooting, that is, the grayscale distribution of the mammary gland image is uneven. In this case, if the image is still displayed according to a fixed contrast, only a part of the breast tissue can be observed, which may cause a missed diagnosis. [0003] At present, the problem of uneven gray scale distribution of breast images is usual...
