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： Coronary artery segmentation is a crucial task in cardiac CT image processing. This is often a tedious task performed manually by an operator. According to the present invention, a method is provided which combines data from multiple cardiac phases during the segmentation process in order to deliver a complete and continuous coronary vessel tree. Advantageously, this may allow for an improved visualization and segmentation of vessels, for example, in coronary CTA.

摘要： The invention relates to a computer tomography method, in which a periodically moving object, especially a heart, is irradiated by a beam bundle. In that process, intermediate images of one and the same subregion of the object are reconstructed using measured values from time intervals from different periods. That is, in each case exactly one period can be allocated to each intermediate image. The time intervals in the individual periods are adjusted in such a way that, after a reconstruction of the intermediate images using measured values that lie in the adjusted time intervals, a similarity measure applied to the intermediate images of the same subregion is minimized. This method can be applied to one, several or all subregions of the object that are reconstructable using measured values from time intervals from different periods. Finally, a computer tomography image is reconstructed, wherein exclusively measured values from the adjusted time intervals are used.

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： 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： The invention relates to a computer tomography method in which a bundle of rays passes through an object that is moving periodically, in particular a heart. During the acquisition of measured values, a movement signal dependent on the movement of the object is sensed. From this movement signal are determined periodically repeated phases of movement, after which a plurality of intermediate images of a region of the object are reconstructed, in particular at a low resolution, using measured values whose times of acquisition were situated in different phases of movement, thus enabling each intermediate image to be assigned to a phase of movement. The phase of movement in which the object moved least in the region is then identified by determining the intermediate image having the fewest motion artifacts. Finally, a computer tomographic image of the region is reconstructed, in particular with a high spatial resolution, from measured values whose times of acquisition were situated in the phase of movement in which there was the least movement by the object in said region.
