Patent number: 12340573Abstract: The present invention relates to landmark and/or temporal event detection. It is proposed to utilize previously learned spatial statistical correlations between multiple landmarks in order to regularize convolutional neural networks (CNNs) either as a post-processing step or during training in order to utilize anatomical prior knowledge, reduce the false-positive prediction rate, and/or increase the accuracy and stability of the algorithm. The proposed apparatus and method may also be applied to improve the detection of correlated events in e.g., time-series by leveraging prior knowledge.Type: GrantFiled: November 17, 2020Date of Patent: June 24, 2025Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Sven Krönke, Daniel Bystrov, Jens Von Berg, Stewart Matthew Young

Publication number: 20240350109Abstract: System (SYS) and related method for imaging support. The system comprises an input interface (IN) for receiving an input image (I1) of a patient acquired by an imaging apparatus (IA). The input image was previously assessed by an image quality assessment module (IQM) and was awarded an image quality, IQ, score. The system's imaging triaging module (TL) retrieves from an image database (DBI) of prior assessed images, a corresponding image (I0) that corresponds to the input image. The corresponding image is a prior image of patient. The imaging triaging module (TL) provides a decision, based on the first IQ score and a second IQ score of the corresponding image (I0), if any, whether or not to acquire a new image (I2) of the patient by the imaging apparatus (IA). The risk of unnecessary retakes can be reduced, thus saving time, dose, and reducing wear-and-tear of the imaging apparatus.Type: ApplicationFiled: August 4, 2022Publication date: October 24, 2024Inventors: MERLIJN SEVENSTER, STEWART MATTHEW YOUNG
