Image positioning method and device, equipment and storage medium

The embodiment of the invention discloses an image positioning method and device, equipment and a storage medium, and the method comprises the steps: obtaining three-dimensional medical images, obtained at a plurality of photographing angles, of a mammary gland part, and determining a region of interest; segmenting the three-dimensional medical image according to the region of interest to obtain asegmentation mask result; and determining an average gradient value corresponding to the contour boundary of the mask region in each tomographic image in the segmentation mask result, and determininga target tomographic image from the tomographic images corresponding to the three-dimensional medical image according to the average gradient values. Through the technical scheme of the embodiment ofthe invention, the clear automatic positioning of the tomographic image can be realized, and the film reading speed is improved. 本发明实施例公开了一种图像定位方法、装置、设备和存储介质，该方法包括：获取乳腺部位在多个拍摄角度下获得的三维医学图像，并确定感兴趣区域；根据感兴趣区域，对三维医学图像进行分割，得到分割掩膜结果；
