Abstract: 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.

The processing unit is configured to instruct the X-ray image acquisition unit to carry out a sequence of scans of a body part of a patient. The X-ray image acquisition unit is configured to provide the processing unit with an X-ray image of the body part for a scan of the sequence of scans. The processing unit is configured to determine that the scan needs to be repeated, wherein the determination comprises analysis of the X-ray image of the body part. The processing unit is configured to determine that an action other than acquisition of the next scan in the scan sequence is required, wherein the determination comprises analysis of the X-ray image of the body part. The processing unit is configured to determine that the X-ray imaging unit is required to carry out the next scan in the scan sequence based on a determination that the scan does not need to be repeated and that an action other than acquisition of the next scan in the scan sequence is not required.

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 mechanism for identifying a position of one or more anatomical landmarks in a medical image. The medical image is processed with a machine-learning algorithm to generate, for each pixel/voxel of the medical image, an indicator that indicates whether or not the pixel represents part of an anatomical landmark. The indicators are then processed in turn to predict a presence and/or position of the one or more anatomical landmarks.

Abstract: 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.

Abstract: An X-ray imaging system (100) includes an X-ray source (110) and an X-ray detector (120) that are separated by an examination region (150) for performing an X-ray imaging operation on an object (160). A processor (140) is configured to identify (S120) one or more internal structures (180) within the object (160), based on a comparison of depth sensor data representing a three-dimensional surface (170) of the object (160), with an anatomical model comprising the one or more internal structures (180). The processor (140) is also configured to compute (S130), using the depth sensor data and the identified one or more internal structures (180), a surface projection (190) of the one or more internal structures, on the surface (170) of the object (160), from a perspective of the X-ray source (110); and to output (S140) an image representation of the surface projection (190) for displaying as an overlay on the surface (170) of the object (160).
