A method for the operation of a computed tomography system and computed tomography system

摘要

The invention relates to a method for the operation of a computed tomography system (2), which has an x-ray detector (6) with a detector base surface (24) and with a detector center (18), wherein for the detection of x-rays sensor pixels (22) non-uniformly over the detector base surface (24) are arranged distributed and wherein either a pitch - factor is selected and, in a function of the distribution of the sensor pixels (22) by means of the detector base surface (24) as well as in a function of the selected pitch - factor a value range for the extent of a reconstruction field (r_R) for an image data processing is determined or a value for the expansion of the reconstruction field (r_R) is selected and, in a function of the distribution of the sensor pixels (22) by means of the detector base surface (24) as well as in a function of the selected value for the expansion of the reconstruction field (r_R) a range of values for the pitch - factor is determined.
