Abstract

The invention discloses a breast image segmentation method based on a flat structure shape filter. The breast image segmentation method comprises the following steps: step S1: the MRI image to be processed is inputted; step S2: the flat plate structure in the MRI image to be processed is enhanced based on the Hessian filter so as to form the intermediate image 1; step S3: the boundary between thebreast tissue and the pectoral muscle is extracted; step S4: the boundary between the breast tissue and the extracorporeal region is extracted; and step S5: the breast tissue is obtained through segmentation. According to the breast image segmentation method based on the flat structure, manual extracting the target region in the image is replaced, the algorithm is full-automatic without any humaninteraction or manual marker, the Hessian filter is applied to highlight the flat structure of the MRI image, and the boundary between the breast tissue and the extracorporeal region (air) and the boundary between the breast tissue and the pectoral muscle can be ingeniously distinguished.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional MRI image processing, and in particular relates to a breast tissue segmentation method based on a flat-shaped structural shape filter. Background technique [0002] Accurate interpretation and analysis of MRI images can provide strong support for early diagnosis of breast cancer. As we all know, MRI images are traditionally interpreted manually. The above-mentioned image reading methods rely heavily on personal experience and are highly subjective, which is not conducive to accurate, objective, and rapid interpretation of MRI images. In some high-density breast MRI images, the breast tissue is not clearly distinguished from the surrounding tissue, and it is difficult to accurately determine its boundary manually. With the rapid development of artificial intelligence technology, computer-aided diagnosis technology plays an increasingly important role in interpreting breast MRI images. H...
