    摘要： The invention relates to a computer tomography scanner comprising a gantry, on the rotor of which one or more displaceable masses are arranged. During rotation of the rotor about a rotation axis, the position of each mass can be changed perpendicular to the rotation axis by means of an adjustment unit. By retaining the rotary momentum of the rotor, the rotational speed is increased when the masses are moved toward the rotation axis, and vice versa. As a result, it is possible to maintain a specific ratio between the heart rate of the examined patient and the rotational speed even if the heart rate of the patient changes during the examination.

    摘要： The reconstruction of computer tomography data is very often based on a parallel rebinning step of the projection data prior to the filtered back projection. In case of cardiac reconstruction, a gating technique is applied to select appropriate projections for a time-dependent image reconstruction. Usually, the gating window is a function of the fan-beam/cone-beam projection only. According to the present invention, a function corresponding to the location on the detector surface, where the respective projection was detected is used to further verify whether the respective projection is truly within the selected gating window or not.

    摘要： An optical shape sensing system employing an elongated device, an optical fiber embedded within the elongated device with the optical fiber, an optical interrogation console and a 3D shape reconstructor. In operation, the optical interrogation console generates reflection spectrum data indicative of a measurement of both an amplitude and a phase of a reflection for each core of the optical fiber as a function of wavelength. The 3D shape reconstructor executes a generation of local strain data for a plurality of positions along the optical fiber responsive to the reflection spectrum data, a generation of local curvature and torsion angle data as a function of each local strain along the fiber, and a reconstruction of the 3D shape of the optical fiber as a function of each local curvature and torsion angle along the optical fiber.

    摘要： A system and method for shape sensing assistance in a medical procedure includes providing (402) a three-dimensional image of a distributed pathway system. A shape sensing enabled elongated device is introduced (406) into the pathway system. A shape of the elongated device in the pathway system is measured (410). The shape is compared (414) with the three-dimensional image to determine whether a given path has been selected relative to a target.

    摘要： An optical shape sensing system employing an optical fiber (20) and one or more reference markers (41). Each reference marker (41) has an identifiable reference tracking position within a reference coordinate system (42). The optical fiber (20) has a reconstruction launch point (21)within the reference coordinate system (42) serving as a basis for an execution of a shape reconstruction of the optical fiber (20) within the reference coordinate system (42). The reconstruction launch point (21)of the optical fiber (20) has a known spatial relationship with each reference marker (41) to facilitate an identification of the reconstruction launch point (21)within the reference coordinate system (42).
