  • Publication number: 20250231123
    Abstract: A method for operating an x-ray device includes: recording a series of x-ray images of a recording area, (e.g., for monitoring the recording area); and determining a series of output images to be output from the x-ray images. When the x-ray images are recorded, there is a repeated change between at least two sets of recording parameters that leads to the different representation of at least two different objects of the recording area in the x-ray images. Further, the output images are determined in each case at least from one set of x-ray images that includes x-ray images recorded with at least two of the at least two sets of recording parameters.

  • Patent number: 12347059
    Abstract: A method for providing a corrected dataset includes receiving a preoperative dataset containing an image and/or a model of an examination region of an examination subject. Length information is received. At least a part of a medical object is arranged intraoperatively in the examination region. The length information includes information relating to a length of the part of the medical object arranged in the examination region. First positioning information relating to a virtual positioning of a predefined section of the part of the medical object arranged in the examination region is determined based on the preoperative dataset and the length information. The method includes receiving and/or determining second positioning information relating to a real positioning of the predefined section. A transformation rule for minimizing a deviation between the first and second positioning information is determined, and the corrected dataset is generated by applying the transformation rule to the preoperative dataset.

  • Publication number: 20250120767
    Abstract: For assessing the effect of a medical instrument during a vascular intervention, a sequence of images of a vessel section and of a first medical instrument that is situated in the vessel section is obtained. A deformation of the vessel section is ascertained based on the sequence of images. First mechanical instrument properties of the first medical instrument are obtained, and mechanical vessel properties of the vessel section are determined based on the first mechanical instrument properties and the deformation. Second mechanical instrument properties of a second medical instrument are obtained. An expected deformation of the vessel section during a vascular intervention on the vessel section using the second medical instrument is assessed based on the second mechanical instrument properties and the vessel properties.

  • Publication number: 20240298979
    Abstract: A method for collision avoidance when positioning a medical imaging device and a patient positioning apparatus includes capturing a representation of an examination object, identifying an examination region based on representation, and identifying an initial acquisition trajectory around an initial isocenter, which enables a 3D reconstruction of the examination region. The imaging device and/or the patient positioning apparatus is positioned such that an isocenter of the medical imaging device coincides with the initial isocenter. A further acquisition trajectory is identified around one further isocenter, which enables a collision-free positioning of the imaging device and a 3D reconstruction of the examination region. The further isocenter specifies a permissible range for relative positionings of the imaging device and the patient positioning apparatus. The imaging device and/or the patient positioning apparatus is repositioned. Repositioning is limited to a permissible range of relative positionings.
