Abstract

The invention relates to a positioning method and device for a highlight focus area, computer equipment and a storage medium, and the positioning method for the highlight focus area is applied to a mammary gland three-dimensional tomography image and comprises the steps: obtaining an interested space in the mammary gland three-dimensional tomography image; performing shape constraint on the spaceof interest to obtain a constrained image; determining a threshold value of regional growth; and carrying out region growth on the constrained image based on the threshold value to obtain a highlightfocus region. According to the positioning method of the highlight focus area, after the interested space is selected in the mammary gland three-dimensional tomographic image, shape constraint is conducted on the interested space to isolate glands around the highlight focus area, the appropriate area growth threshold value is determined, and therefore segmentation of the highlight focus area is achieved, and many inappropriate threshold values are removed in the positioning process. According to the positioning method, the processing speed is increased, and the segmentation accuracy is improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a positioning method, device, computer equipment and storage medium for a highlighted lesion area. Background technique [0002] When detecting breast tissue, it is often necessary to locate highlighted areas such as lumps and lesions in breast images. The traditional positioning method for these highlighted areas in mammary images is generally for two-dimensional mammography image processing, and the highlighted area is segmented by simple region growing, but the lesion area is easy to adhere to other highlighted glands, resulting in inaccurate positioning . Contents of the invention [0003] Based on this, it is necessary to address the above technical problems and provide a method, device, computer equipment and storage medium for locating the highlighted lesion area, which can locate the highlighted lesion area according to the three-dimensional tomographic image of the brea...
