Patent number: 11957497Abstract: A method for processing breast tissue image data includes processing the image data to generate a set of image slices collectively depicting the patient's breast; for each image slice, applying one or more filters associated with a plurality of multi-level feature modules, each configured to represent and recognize an assigned characteristic or feature of a high-dimensional object; generating at each multi-level feature module a feature map depicting regions of the image slice having the assigned feature; combining the feature maps generated from the plurality of multi-level feature modules into a combined image object map indicating a probability that the high-dimensional object is present at a particular location of the image slice; and creating a 2D synthesized image identifying one or more high-dimensional objects based at least in part on object maps generated for a plurality of image slices.Type: GrantFiled: March 11, 2022Date of Patent: April 16, 2024Assignee: HOLOGIC, INCInventors: Haili Chui, Liyang Wei, Jun Ge, Xiangwei Zhang, Nikolaos Gkanatsios

Patent number: 8175350Abstract: An image guidance system is provided for improving tissue culture extraction where the tissue is extracted under the guidance of first and second knowledge-based systems. The first knowledge-based system provides initial suggested regions of interest for tissue biopsy in an internal organ. These regions of interest are then confirmed as being of interest of being benign by the second knowledge-based system. Information from two different sources may provide a more accurate, intelligent and robust method that helps in selecting biopsy sites accurately, such that suspicious regions are not overlooked and the benign regions are not unnecessarily operated upon. This not only helps in better diagnosis and treatment, but also helps reduce pain to the patient, in addition to reducing wastage of resources and invaluable time.Type: GrantFiled: January 15, 2008Date of Patent: May 8, 2012Assignee: Eigen, Inc.Inventors: Jasjit S.
