Abstract: A method for providing feedback data in a medical imaging system (22) for a medical imaging process, comprising the steps of: providing, by a calculation unit, a simulation model, trained to predict an appearance of a medical image to be acquired by using the medical imaging system (22) from a relation between subject positioning data associated with a captured positioning of a subject (27), equipment positioning data associated with a captured positioning of at least one medical care and/or monitoring equipment (28, 30) arranged in or at the subject (27) in a medical imaging system (22), and medical image data associated with the subject positioning data and the medical care and/or monitoring equipment positioning data (S10); obtaining, by the calculation unit, from at least one measuring means (25, 26), current subject positioning data of a subject (27) and current medical equipment positioning data of at least one medical care and/or monitoring equipment (28, 30) arranged in or at the subject (27) in the medical imaging system (S20); determining, by the calculation unit, feedback data by feeding the obtained current subject positioning data and the obtained current medical equipment positioning data into the simulation model outputting the feedback data, wherein the feedback data comprise at least simulated medical image data predicted by the simulation model from the obtained current subject positioning data and current medical equipment positioning data (S30); providing, by a provision unit, the feedback data (S40).

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.

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.

Abstract: An X-ray imaging system (XI) configured for phase contrast and/or dark-field imaging The system comprises an X-ray source (XS) operable to cause X-radiation to emanate from a focal spot (SF) of the source (XS) and an X-ray sensitive detector (D) operable to SMF detect the X-radiation after interaction of said X-radiation with an object to be imaged, if present, between the X-ray source and the detector (D). A control logic (CL) is operable to cause the X-ray imaging apparatus to operate in any one of two modes, an object image acquisition mode and a scattering measurement mode. When in scattering measurement mode, the X-radiation receivable at the detector comprises a higher proportion of scattering radiation than in X-radiation receivable when the system is in object image acquisition mode.

Abstract: The invention relates to a system and a method for active grating position tracking in X-ray differential phase contrast imaging and dark-field imaging. The alignment of at least one grating positioned in an X-ray imaging device is measured by illuminating a reflection area located on the grating with a light beam, and detecting a reflection pattern of the light beam reflected by the reflection area. The reflection pattern is compared with a reference pattern corresponding to an alignment optimized for X-ray differential phase contrast imaging, and the X-ray imaging device is controlled upon the comparison of the reflection pattern and the reference pattern.

Abstract: A grating structure is provided with arc-shaped stabilizing bridging structures on the lamellae that allow for bending the grating to account for stresses and deformations induced by the bending process to obtain a more stable curved grating structure more efficiently.
