  • Patent number: 12502155
    Abstract: An imaging system (MIS), optionally a medical imaging system, with wireless communication capability and related method. The imaging system comprises a gantry (RG) rotatable around a rotation axis. The gantry includes a detector device (D) capable of recording, in plural spatial positions, measurement data in relation to a subject (such as a patient) (PAT) to be imaged. The system also includes a radio transmitter (TX) for generating a directed radio beam propagatable along a propagation axis to transmit the measurement data to a radio receiver (RX). The radio transmitter (TX) is arranged at the rotatable gantry and is operable so that the propagation direction intersects the rotation axis in a location that is situated away from the rotatable gantry.

  • Publication number: 20250315964
    Abstract: A computer-implemented method of registering medical images, is provided. The method includes computing a spatial transformation between a first projection image (P1) and a volumetric image. The first projection image (P1) is generated from a first position (POS1) of a projection imaging system (110). Input defining the region of interest (ROI) in the volumetric image is received. One or more adjustments (TP1?P2) to the first position (POS1) of the projection imaging system are then calculated based on the spatial transformation and the received input, to provide a second position (POS2) of the projection imaging system for generating a second projection image (P2) representing the region of interest (ROI). A second projection image (P2) representing the region of interest (ROI) is then received. The second projection image (P2) is generated from the second position (POS2).

  • Publication number: 20250302535
    Abstract: The invention relates to a system and to a method for assistance in an image guided surgical procedure, in particular in image guided percutaneous needle interventions such as for kidney stone removal. With the system and the method, it may be possible to provide an automatic recommendation of control scans at critical phases during the intervention. To this end, in an initial image, a structure at risk is identified and an intervention path to a target location is provided. With an evaluation unit, it can be evaluated whether a spatial relation between a) a tracked position of a medical instrument and b) the location of the structure at risk and/or the intervention path meets a predefined criterion. If the predefined criterion is found to be met, an acquisition of a control scan may be recommended automatically.

  • Publication number: 20240202943
    Abstract: The present invention relates to a computer-implemented method for generating a simulated CBCT image based on a computed tomography image. A computed tomography image is converted into attenuation coefficients of the represented tissue, and the computed tomography image is forward-projected to a projection image based on scanner parameters of a simulated CBCT scanner. After the addition of artificial noise to the projection image representing noise detected by the simulated CBCT scanner, the projection image is back-projected with a reconstruction algorithm for the generation of a simulated CBCT image of the subject. The present invention relates further to a method for generating training data for training an artificial intelligence module based on the simulated images, and to methods for registering a computed tomography image to a CBCT image and for segmenting a CBCT image with an artificial intelligence module trained with training data comprising the simulated CBCT images.

  • Patent number: 11861898
    Abstract: Augmented reality (AR) servicing guidance uses a mobile device (30, 90) with a display and a camera. Computer vision (CV) processing (102) such as Simultaneous Location and Mapping (SLAM) is performed to align AR content (80) with a live video feed (96) captured by the camera. The aligned AR content is displayed on the display of the mobile device. In one example, the mobile device is a head-up display (HUD) (90) with a transparent display (92, 94) and camera (20). In another example the mobile device is a cellphone or tablet computer (30) with a front display (34) and a rear-facing camera (36). The AR content (80) is generated by CV processing (54) to align (70) AR content with recorded video (40) of a service call. The aligning (72) includes aligning locations of interest (LOIs) identified in the recorded video of the service call by a user input.
