Publication number: 20240153037Abstract: A method and system for correcting a difference in contrast agent density in a sequence of contrast-enhanced image frames. A reference image frame is defined in the sequence of contrast-enhanced image frames, and segmentation is performed on the reference image frame to determine a location of a region of interest within the reference image frame. The region of interest is a region of the reference image frame that contains contrast agent. Other image frames in the sequence of contrast-enhanced images are corrected based on a difference in contrast agent density/image intensity in the region of interest relative to the region of interest in the reference image frame.Type: ApplicationFiled: March 3, 2022Publication date: May 9, 2024Inventors: Sebastian Wild, Frank Michael Weber, Irina Waechter-Stehle, Jochen Peters, Arne Ewald, André Gooßen, Matthias Lenga, Tobias Wissel, David Prater

Publication number: 20240127432Abstract: A system and method for achieving more accurate results when applying an image processing task to a series of medical images of a patient, without significantly increasing processing resource. The proposed system and method is based on receiving a plurality of image sequences of a particular anatomical region, each capturing cyclical movement of an anatomical object. Each image sequence is supplied to a classifier module which employs use of one or more machine learning algorithms to derive at least one score for each image sequence indicative of predicted success or quality of a result of the image processing task if applied to the given image series. This permits an assessment to be made in advance of which of the plurality of image series is most likely to result in the best (e.g. highest quality, or greatest amount of information) results from the image processing task.Type: ApplicationFiled: January 24, 2022Publication date: April 18, 2024Inventors: Alexandra Groth, Tanja Lossau, Irina Waechter-Stehle, Frank Michael Weber, Jochen Peters, Sebastian Wild, Arne Ewald, Andre Goossen

Patent number: 9901319Abstract: The invention relates to peripheral equalization during a mammography X-ray examination. High contrast tissue pixel values are removed from the background estimate by finding the minimum intensity values of the pixel located in the neighborhood, which have approximately the same distance to the skin line. Thus, high attenuating pixel values may be removed from the estimate and replaced by lower attenuating tissue pixel values. After a minimum filtration, a conventional peripheral equalization is performed. This may result in less overshoots and intensity values for higher attenuating structures in the peripheral region may become more consistent with intensity values for higher attenuating structures in the fully compressed region.Type: GrantFiled: November 16, 2015Date of Patent: February 27, 2018Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Frank Bergner, Hanno Heyke Homann, André Goossen, Hanns-Ingo Maack
