  • Publication number: 20240013468
    Abstract: The present invention relates to object visualization. In order to provide a facilitated visualization of a subject's interior structure, an object visualization device (10) is provided comprising an image supply (12), a data processor (14) and an output (16). The image supply provides a 2D X-ray image of the object and also 3D image data of the object. The data processor registers the 3D image data to the 2D X-ray image and detects a viewing direction used for generating the 2D X-ray image. The data processor also determines a viewing direction for projecting the 3D image data to generate a matching view of the 3D image data based on the viewing direction used for generating the 2D X-ray image.

  • Patent number: 11224496
    Abstract: The present invention relates to patient monitoring, such as hemodynamic monitoring. In order to perform provide monitoring in various scenarios, a patient monitoring device (10) is provided that comprises a patient medical monitoring unit (12) and an information unit (14). The patient medical monitoring unit is configured to perform monitoring at least one physiological parameter of a patient. The information unit is configured to provide a data carrier signal (16) indicative of information about the patient medical monitoring unit, for example, upon connection to a monitoring system. The data carrier signal is provided as an analogue sequence (18) comprising a predetermined waveform (20) indicative of the information about the patient medical monitoring unit.

  • Patent number: 10887492
    Abstract: An apparatus (IP) and a method to generate temporally-aligned image frames for image-streams (LS, RS) in a multi-channel (CR, CL) imaging system (100). The apparatus (IP) allows reducing or removing temporal distance artifacts that occur when processing the frames into combined image material. The apparatus can also be used to improve signal-to-noise ratio of the frames. The multi-channel imaging system (100) may be a stereoscopic imager.

  • Patent number: 9877687
    Abstract: The present invention relates to collimation of X-ray radiation and comprises an X-ray source arrangement for medical imaging, the X-ray source arrangement comprising an X-ray source, and an X-ray beam shutter device. The X-ray source has at least at a first and a second focal spot position distanced apart from each other in a direction transverse to a main radiation direction. The X-ray beam shutter device comprises at least a first pair of shutters defining a first diaphragm, and at least a second pair of shutters defining a second diaphragm. The first pair of shutters is configured for alignment with a first line-of-sight between the first focal spot position and a center of a detector, and the second pair of shutters is configured for alignment with a second line-of-sight between the second focal spot position and a center of a detector. The first and the second diaphragm partly overlap.

  • Patent number: 9615802
    Abstract: An X-ray imaging system includes an x-ray image acquisition unit, a display unit, an input unit, and adapting means. The x-ray image acquisition unit acquires a first image of a volume of interest of an object in a first projection direction and acquires a second image in a second projection direction. The display unit displays the first and the second image. The input unit determines the second projection direction by an input of a user. The user input includes a change in a viewing-direction of the user viewing the first image. The adapting means adapt a spatial relation between the projection direction of the image acquisition unit and the volume of interest of the object such that the projection direction correlates with the second viewing direction.

  • Publication number: 20160081636
    Abstract: The present invention relates to collimation of X-ray radiation. In order to provide an X-ray collimation suitable for focal spots spaced apart from each other with improved use of the provided radiation beam, an X-ray source arrangement (10) for medical imaging is provided. The X-ray source arrangement comprises an X-ray source (12), and an X-ray beam shutter device (14). The X-ray source is configured to generate X-ray radiation (18) at least at a first (20) and second focal spot position (22) distanced apart from each other in a direction (D) transverse to a main radiation direction (R). The X-ray beam shutter device comprises at least a first pair of shutters (28) defining a first diaphragm (30) for a first X-ray beam generated at the first focal spot position, and at least a second pair of shutters (34) defining a second diaphragm (36) for a second X-ray beam generated at the second focal spot position.

  • Publication number: 20150071405
    Abstract: The present invention relates to providing spatial information of a volume of interest of an object. In order to reduce complexity of a work flow in a hospital environment when X-ray imaging is used, an X-ray imaging system (10) for providing spatial information of a volume of interest (20) of an object is provided, wherein the system comprises an x-ray image acquisition unit (12), a display unit (14), an input unit (16), and adapting means (18). The x-ray image acquisition unit is configured to acquire a first image of a volume of interest of an object in a first projection direction and to acquire a second image in a second projection direction. Further, the display unit is adapted to display the first and the second image. In addition, the input unit is configured for a determination (22) of the second projection direction by an input of a user (24); wherein the user input comprises a change in a viewing-direction (15) of the user viewing the first image.

  • Patent number: 6805896
    Abstract: The invention relates to a dry clouding agent for dry beverage mixes prepared by drying an aqueous mixture, which on a dry weight basis, comprises (a) from 15 to 35% by weight of finely divided TiO2; (b) from 35 to 55% by weight of a suspending agent; and (c) from 20 to 40% by weight of a spacing agent with the proviso that the weight ratio of TiO2 to suspending agent is 1:1.1 to 1:3. Further the invention relates to a method for producing said clouding agent which can be used in dry beverage mixes. Those beverage mixes provide increased opacity stability properties in the aqueous produced therefrom.
