Abstract: An apparatus for medical imaging of a patient, including an object of interest, is provided. The apparatus comprises a patient support unit, a processor, and a display. The patient support unit is configured to receive a patient. The processor is configured to receive scout images of the patient acquired in respective positions of the apparatus. Each respective position is represented by a position parameter. The processor is further configured to select at least one iso-centering image from the scout images by geometrical calculation using the position parameter of each scout image and a position parameter representing a present position of the apparatus. The processor is further configured to adapt the appearance of the at least one iso-centering image according to the present position of the apparatus. The display is configured to present the at least one adapted iso-centering image.

Abstract: The present invention relates to iso-centering an object of interest prior to computer tomography (CT) scanning for examination of a patient in a C-arm CT examination apparatus. In order to provide facilitated positioning and to overcome or at least minimize these drawbacks, a C-arm CT examination apparatus (10) for CT scanning for examination of a patient is provided. The apparatus comprises a patient support unit, an acquisition unit, a data processing and control unit, and a display unit. The patient support unit is configured to bed a patient, free of motion, on the patient support. The acquisition unit is configured to acquire scout images of the patient including the object of interest in a respective position of the apparatus having position parameters.

Abstract: A system is provided for simultaneously displaying video data of multiple video sources (040, 042) on a display. The system comprises a video input (120) for receiving the video data (122) of the multiple video sources; a display processor (140) for generating display data (142) to display the video data of the multiple video sources in respective viewports (1A-2F) on a display. The display processor is further arranged for, if needed to fit respective ones of the viewports, spatially scaling the video data of one or more of the multiple video sources to obtain said fit; and generating a visual indicator (300-320) for visually indicating whether the video data in one of the viewports has been spatially scaled from its native spatial resolution. By providing the visual indicator as part of the display data, the system may warn the user that the video data in one of the viewports may comprise undesirable artifacts which may hinder interpretation of the video data.

Abstract: The invention relates to a processing system (200) that is arranged to cooperate with an optical-shape-sensing-enabled elongated interventional device (1020, 1120, 1220, 1320, 1420), such as a catheter comprising an optical fiber. A reconstructed shape data providing unit (130) provides reconstructed shape data for the interventional device (1020, 1120, 1220, 1320, 1420). A virtual marking provider unit (140) provides at least one virtual marking (1020A, 1020B, 1101, 1102, 1103, 1201, 1203, 1204, 1301, 1302, 1401) based on the reconstructed shape data, for example as overlay to a x-ray image. The present invention thus turns any OSS-enabled device into a calibrated device, suitable for all kinds of live 3D measurements.
