  • Publication number: 20260198876
    Abstract: An apparatus and a method for reciprocal registration of a shape-detecting instrument, an imaging X-ray system, and an X-ray system including a corresponding apparatus are provided. The apparatus includes a registration facility. The registration facility is configured such that the shape-detecting instrument, until attaining a registering position, may be introduced into the registration facility. The spatial relative position of the registering position may be kept at least temporarily unchanged in relation to the X-ray system and is assumed to be known for the method. A detecting facility that is configured to detect when the shape-detecting instrument attains the registering position is also provided. A registering signal may be generated by the detecting facility when the detecting facility detects that the shape-detecting instrument attains the registering position.

  • Patent number: 12629049
    Abstract: A method for automatic position determination review during position tracking of an object inserted in a hollow organ of a patient by an electromagnetic tracking (EMT) system in the presence of an X-ray device with a movable acquisition system includes providing a registration of the EMT system to the acquisition system. A reference image of the hollow organ of the patient is provided, a registration of the reference image is provided to the acquisition system, a position of the object is determined by the EMT system, and an associated position on the reference image is determined. A plausibility criterion and/or a boundary condition is applied for reviewing a plausibility of the position determined by the EMT system based on the reference image. If the plausibility criterion and/or the boundary condition is violated, a position correction of the position determined by the EMT system and/or an alternative position determination is performed.

    Abstract: For visual support in a medical intervention on a hollow organ of a patient, reference data that includes a reference representation of the hollow organ is obtained, an X-ray projection image of the hollow organ is generated, and items of overlay information are determined based on the reference data. The reference data includes items of planning information relating to a location of a characteristic feature of the hollow organ in the reference representation. A reference volume is determined in the reference representation as a function of the items of planning information. A reconstruction of a volume of the patient corresponding to the reference volume is generated using a tomosynthesis method. Registration data is generated in that the reference volume is registered in relation to the reconstruction and the items of overlay information are overlaid on the X-ray projection image as a function of the registration data.

  • Patent number: 12502227
    Abstract: A method for providing a corrected dataset includes receiving a preoperative dataset having an image and/or a model of an examination region in an examination subject. Intraoperatively, a first part of a medical object is arranged in the examination region and a second part of the medical object is arranged outside the examination subject. Positioning information relating to a spatial positioning of the second part of the medical object is received. An entry angle of the medical object into the examination subject is determined using the positioning information. An intraoperative dataset having an image of the examination region is received. A conversion instruction is determined based on the entry angle of the medical object to minimize a deviation between the preoperative and the intraoperative dataset, and the corrected dataset is generated by applying the conversion instruction to the preoperative dataset. The corrected dataset is provided.

  • Publication number: 20250366938
    Abstract: A method for controlling movement of an elongated medical instrument within a body that along its length includes an optical fiber configured for optical shape capture is provided. An insertion section of the fiber is located in the body. The method includes measuring a bend at multiple positions of the fiber, at least along the insertion section of the fiber. A three-dimensional (3D) shape of the insertion section of the fiber in the body is determined from the measured bend. A sequence of movements, with which a holding section of the instrument is to be moved, is determined based on the shape of the insertion section, so that the bend of the instrument in the insertion section may be decreased if the holding section is moved correspondingly. The sequence of movements is output.

  • Publication number: 20250345119
    Abstract: A method for operating an X-ray facility includes supplying a vascular model of a vascular structure. A target position of an instrument that may move in the vascular structure, a starting position of the instrument in the vascular structure of the vascular model, and a path in the vascular structure of the vascular model are marked in the vascular model. Support points are defined along the path. An optimized course of projection geometries is ascertained for the support points in an optimization process of a target function using the vascular model. Apart from at least one first term, the target function also includes at least one second term that minimizes the number of changes in the projection geometry along the path due to movement of the support. Positioning parameters for actuating the positioning facility are ascertained for each projection geometry.
