Abstract: The present invention relates to prospective analysis of subject and/or implant positioning. Provided is a computer-im-plemented method for assisting positioning of a subject having an orthopedic implant in X-ray imaging. The method comprises applying one or more radiofrequency, RF, signals to an anatomy of interest of the subject where the orthopedic implant is located. The method further comprises detecting a response signal and/or signal change in response to the applied RF signal impacting the orthopedic implant and tissue being adjacent to and/or surrounding the implant, and determining, from the detected response signal and/or signal change, an implant positioning estimation relative to an X-ray imaging device. Further, the method comprises determining, from the implant positioning estimation, a feedback being indicative for positioning the X-ray imaging device and the subject to each other with respect to a target positioning, to be provided for assisting the positioning.

Abstract: Technology provides baseline images for diagnostic applications, including receiving a diagnostic image relating to a condition of a patient, the diagnostic image reflecting one of a normal state or an abnormal state of the condition, and generating a baseline image via a neural network using the diagnostic image, where the neural network is trained to generate a prediction of the diagnostic image reflecting a normal state of the condition. The neural network can include a generative adversarial network (GAN) trained only on image data with a normal state of the condition, where generating the baseline image includes an optimization process to maximize a similarity between the diagnostic image and a response of the GAN. Generating the baseline image can include selecting a portion of the diagnostic image, and adjusting a relevance weighting to be applied to the selected portion of the diagnostic image in the optimization process.

Abstract: The present invention provides a retrospective analysis of subject and/or implant positioning. Provided is a method and device for assisting positioning of a subject having an implant in X-ray imaging. The method comprises the steps of receiving (S1) X-ray image data of the subject including the implant, receiving (S2) exam request data indicating at least an exam type to be performed for the specific implant, and determining at least one set of image features being assigned to the requested exam type and indicative for positioning of the subject and/or the implant relative to an X-ray imaging device. Further, the method comprises analyzing (S3) an image content of the received X-ray image data for the determined set of image features, and determining (S4), from the analysis of the image content, a feedback being indicative for positioning the subject and the X-ray imaging device to each other with respect to a target positioning, to be provided for assisting the positioning. Advantageously, the set of image features defines at least a contour of the implant, wherein the contour is determined to meet a corresponding target contour defined by the set of image features in case of meeting the target positioning.

Abstract: A digital image (40) comprises pixels with intensities relating to different energy levels. A method for processing the digital image (40) comprises the steps of: receiving first image data (42a) and second image data (42b) of the digital image (40), the first image data (42a) encoding a first energy level and the second image data (42b) encoding a second energy level; determining a regression model (44) from the first image data (42a) and the second image data (42b), the regression model (44) establishing a correlation between intensities of pixels of the first image data (42a) with intensities of pixels of the second image data (42b); and calculating residual mode image data (46) from the first image data (42a) and the second image data (42b), such that a pixel of the residual mode image data (46) has an intensity based on the difference of an intensity of the second image data (42b) at the pixel and a correlated intensity of the pixel of the first image data (42a), the correlated intensity determinate by applying the regression model to the intensity of pixel of the first image data (42a).

Abstract: The present invention relates to patient positioning. In order to facilitate patient positioning, an apparatus is provided that comprises an input unit, a processing unit, and an output unit. The input unit is configured to receive an X-ray image of an anatomy of interest of a patient obtained from a first image acquisition and a target set of pose parameters describing a target position of the anatomy of interest for image acquisition. The processing unit is configured to detect the anatomy of interest in the X-ray image, to determine a set of pose parameters describing a current position of the detected anatomy of interest in the first image acquisition, to determine a difference between the determined set of pose parameters and the target set of pose parameters, and to construct a trajectory that defines a sequence of sets of pose parameters for bringing the anatomy of interest from the current position to the target position, if the difference is equal to or greater than a pre-defined threshold. The processing unit is further configured to generate a series of X-ray images according to the received X-ray image and the sequence of sets of pose parameters in the trajectory to synthesize a virtual fluoroscopic image sequence of frames representing an animated radio graphic imaging during re-positioning of the patient. The output unit is configured to provide the synthetic Virtual fluoroscopic image sequence for positioning guidance for a second image acquisition.

Abstract: An image processing system and related method. The system comprises an input interface (IN) configured for receiving an input image. A filter (FIL) of the system filters said input image to obtain a structure image from said input image, said structure image including a range of image values. A range identifier (RID) of the system identifies, based on an image histogram for the structure image, an image value sub-range within said range. The sub-range being associated with a region of interest. The system output through an output interface (OUT) a specification for said image value sub-range. In addition or instead, a mask image for the region of interest or for region or low information is output.
