Abstract
A method is disclosed for acquiring measured data by way of a computed tomography system, wherein the measured data is acquired by a detector unit disposed opposite the radiation source during a rotation of a radiation source around an examination object. In at least one embodiment, the rotation is subdivided into succeeding time segments during each of which measured data is acquired, and each of the succeeding time segments has either a first length or a second length consisting of two predefined lengths.

A method for acquiring measured data by way of a computed tomography system, comprising:
- subdividing a rotation, of a radiation source around an examination object by a detector unit disposed opposite the radiation source, into succeeding time segments;
- and
- acquiring the measured data during each of the succeeding time segments, each of the succeeding time segments including either a first length or a second length including two predefined lengths wherein, in order to decide which of the two predefined lengths a time segment is to have, a second subdivision of the rotation into succeeding angle segments having the same angle progression is taken into account.
A detector unit for a computed tomography system, the detector unit being disposed opposite a radiation source in the computer tomography system and being adapted to acquire measured data during a rotating movement of the radiation source around an examination object, the rotation being subdivided into a series of succeeding time segments during each of which the measured data is acquired, the detector unit comprising at least one device to determine lengths for the succeeding time segments such that each time segment includes, in each case, either a first length or a second length consisting of two predefined lengths wherein, in order to decide which of the two predefined lengths a time segment is to have, a second subdivision of the rotation into succeeding angle segments having the same angle progression is taken into account.
