摘要： The invention relates to an imaging method, especially a computerized tomography method, with which an object is penetrated by rays from different directions and measured values, which depend upon the intensity of the rays after penetrating the object, are acquired by a detector unit. From these measured values, an object image is reconstructed by means of back projection of measured-value-dependent back projection values. Therein, the object image is divided into overlapping, quasi-spherically symmetric image segments, each being defined by an image value and a quasi-spherically symmetric base function. Furthermore, during the back projection, the back projection values are added in proportions to the image values, wherein the proportion of a back projection value, which is added during the back projection to an image value, is dependent on a proportionality factor, which is equal to the average value of the line integrals of the base function belonging to the respective image value along those rays that have generated the measured value, on which the respective back projection value is dependent.

摘要： Controlled local application of drugs to a certain part of a body of a patient may be of major importance during a cardiac CT scan. By transporting the drugs in containers which prevent an application of the drugs and by rupturing only those containers which are located in the vicinity of the part of the body of a patient to which the drugs have to be applied, a local application of the drugs may be performed. According to an exemplary embodiment of the present invention, the rupturing and therefore the application of the drugs may be triggered by a monitoring algorithm which evaluates changes in the heart beat rate of the patient. Advantageously, the method allows for a local delivery of the drugs on a fine time scale and therefore for a fast control of the heart beat rate during the CT scan.

摘要： The invention relates to a computed tomography method for forming images of an object to be examined which is arranged in an examination zone. The examination zone is scanned by means of a conical X-ray beam. In order to enable images having a high image quality to be formed from a selected imaging zone while making an as small as possible computational effort, the invention proposes the following steps: a) selecting an imaging zone of the object to be examined, b) determining the sub-regions of the X-ray detector on which the imaging zone of the object to be examined is projected during the acquisition of the projection data, c) forming sub-projection data by selecting the projection data associated with the sub-regions from the acquired projection data, and d) reconstructing the desired image from the sub-projection data by backprojection.

摘要： The invention relates to a computed tomography method in which a rebinning operation is carried out so as to form parallel fan beams whose rays traverse a plane, containing the axis of rotation, in equidistant puncture points. Reconstruction is performed for rays which extend perpendicularly to said planes. Such a transition from a cone beam geometry to a parallel beam geometry enables very fast reconstruction which can be carried out notably for CT fluoroscopy.

摘要： The invention relates to a computed tomography apparatus in which the measuring data acquired in a first measuring window enter the reconstruction with a weight other than that of the measuring data that can be acquired in a second measuring window, the second measuring window being situated centrally relative to the first measuring window and being smaller than the first measuring window. Depending on the weighting of the measuring data, the resultant CT image exhibits either smaller motional artefacts or a spatially more uniform noise.

摘要： The invention relates to a reconfiguration method designed to be implemented in a computer system, for compensating failures of a sensor system (1). The sensor system includes at least one sensor (2, 50) for measuring (12, 22) system states of an application system (11, 21) and at least one system model (4) for describing the application system, which together form at least one first observer (6) for estimating system states in order to provide system states for an allocated data processing device (14, 24). According to the method, failure states for a first observer are determined from deviations, which occur as a result of the comparison between a number of states measured by the sensor or sensors and a state estimated by the system model.
