Embodiment Construction
[0050] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0051] figure 1 It is a schematic flow chart of a method for locating calcification clusters in an embodiment, such as figure 1 As shown, a method for locating calcification clusters is applied to breast three-dimensional tomographic images, including:
[0052] Step S120: Obtain a space of interest in the three-dimensional tomographic image of the breast.
[0053] Specifically, when detecting and locating calcification clusters, firstly, a digital breast tomography (Digital Breast Tomsynthesis, referred to as DBT) technique can be used, that is, a fixed breast is exposed...

The present application relates to a calcification cluster positioning method, device, computer equipment and storage medium, a calcification cluster positioning method applied to a three-dimensional breast tomographic image, including: acquiring a space of interest in the breast three-dimensional tomographic image; Segmenting the space of interest to obtain candidate calcification points; screening out definite calcification points from the candidate calcification points; clustering the definite calcification points to obtain calcification cluster regions. The method for locating calcification clusters mentioned above selects the space of interest in the three-dimensional tomographic image of the breast, then it can segment and screen the space of interest, and then cluster the calcification points to realize the positioning of the calcification clusters. During the positioning process, only the reconstruction The final three-dimensional tomographic image data of the breast does not need to use the original data of the scan, which reduces the amount of processed data and makes the positioning of the calcification cluster more rapid and accurate.
Description
technical field [0001] The invention relates to the field of medical devices, in particular to a method, device, computer equipment and storage medium for locating calcification clusters. Background technique [0002] Three-dimensional breast tomography (Digital Breast Tomsynthesis, referred to as DBT) can significantly reduce the overlap of breast tissue, and can better observe breast tissue lesions. Locating the calcified areas that are only present in a portion of the image can aid in faster interpretation. [0003] Traditional detection methods for calcified areas in breast three-dimensional tomographic images, when processing, some need to use the scanned original image, combined with the original image and the reconstructed image for detection, some are processed on a single image, and finally And then synthesized into 3D images, such a method is relatively complicated, and the amount of calculation data is large, which affects the speed and accuracy of positioning. ...
