摘要： A computer-implemented method of providing pose adjustment information (110) for adjusting a pose of an anatomical structure (120) with respect to a projection X-ray imaging system (130a, 130b) in order to acquire a target X-ray projection image representing the anatomical structure, is provided. An initial X-ray projection image representing the anatomical structure and/or a camera image representing the anatomical structure, are inputted into a neural network. The initial X-ray projection image is acquired with the anatomical structure in an initial pose (α1) with respect the projection X-ray imaging system (130a, 130b). The camera image is acquired by a camera configured to view the anatomical structure, and is acquired with the anatomical structure in the initial pose. In response to the inputting, the neural network generates pose adjustment information (110) for adjusting the initial pose (α1) of the anatomical structure with respect to the projection X-ray imaging system (130a, 130b) in order to acquire the target X-ray projection image.

摘要： A method and system for providing saliency maps for a deep learning model. The method comprises inputting an input image into the deep learning model trained to output a metric score, from a plurality of metric scores, for the input image. A supportive saliency map is generated for the input image, from the deep learning model, corresponding to a first range of the metric scores for the image, thereby providing one or more supportive regions of the image indicative of the first range of metric scores. A distractive saliency map is also generated for the image, from the deep learning model, corresponding to a second range of the metric scores for the image, thereby providing one or more distractive regions of the image indicative of the second range of metric scores.

摘要： A method for obtaining a medical image at a target plane. The method comprises obtaining a three-dimensional, 3D, volume containing an anatomical structure and identifying the anatomical structure in the 3D volume. The geometry of the anatomical structure in the 3D volume is analyzed and the target plane is registered to the 3D volume based on the analysis of the geometry of the anatomical structure. The medical image is extracted from the 3D volume at the registered target plane.

摘要： A method for acquiring a set of target planar views through an anatomy of interest through processing of 3D ultrasound image data. The method processes received 3D image frames in real time to extract target planes and to process each extracted plane with a quality check algorithm. A record is kept of all target planes which have been acquired with sufficient quality, for example by removing them from a list of planes still to be captured. Optionally, each new frame need only be processed to extract planes which are yet to be acquired with sufficient quality. A user interface display is dynamically controlled so that a user is always presented with a real-time display of a planar view of at least one of the planes still to be captured with sufficient quality. The user is thus continually provided the optimal guidance imagery for controlling the acquisition apparatus to acquire new 3D frames which include image data from which the still required 2D planes can be successfully extracted with high quality.

摘要： A medical imaging and segmentation method comprising utilizing segmentation results obtained for 3D frames earlier in a same imaging session to initialize a segmentation model for subsequent 3D frames. This accelerates and stabilizes segmentation results, particularly in the context of a scanning procedure in which segmentation is performed in real time (on-the-fly) for each acquired frame.

摘要： A computer-implemented method of providing pose information for X-ray projection images, is provided. The method includes segmenting an X-ray projection image (120) to identify a plurality of projected sub-regions (150 1..m ) of an anatomical structure, generating a pose metric for the X-ray projection image (120) based on a relative size of two or more of the projected sub-regions (150 1..m ) in the segmented X-ray projection image (120), and outputting the pose metric to provide the pose information for the X-ray projection image (120).

摘要： A system (SYS) and related method for enabling tomographic imaging with a non-rotational radiography imaging apparatus (IA). An input interface (IN) receives, whilst there is relative motion between patient (PAT) to be imaged and a detector (DM) or X-ray source (XS) of the imaging apparatus, i) 3D position measurement readings acquired by an optical fiber-based system (OFS) via a set of optical-fiber based sensors (Si) arranged, for example, at the patient. The measurement readings are relatable to poses assumable by the patient during motion relative to the detector. Projection imagery (λ) acquirable by the imaging apparatus of the patient during, or before and after, such relative motion is also received. A projection direction determiner (PDD) determines projection direction data (α) for the projection imagery (λ) based on the 3D position measurement readings (P). The projection imagery associated with the projection direction data may be used for tomography.

摘要： The invention concerns a device, a method, and an X-ray-system comprising such a device, for assisting in positioning at least one body part of a patient for an X-ray acquisition by an X-ray system, comprising a display for displaying the body part to a user, a first camera on a first side of the display, arranged and configured to monitor the body part, wherein the body part is monitored from a viewing perspective of the device, and a processing unit. The processing unit is configured to estimate an actual bone position of the body part based on one or more images captured by the first camera, determine a target bone position, calculate a difference between the estimated actual bone position and the target bone position. The device is configured to display by the display at least one of the target bone position, the estimated actual bone position, and the calculated difference between the estimated actual bone position and the target bone position overlaid over at least one image of the body part. The device is configured to adapt the displaying of the at least one of the target bone position, the estimated actual bone position, and the difference between the estimated actual bone position and the target bone position upon a change of the viewing perspective of the device.
