Acquisition method for projection data records of investigation object, involves changing of object with time constants, where roentgen beam has pass through on way from roentgen source to roentgen detector

摘要

The method involves changing of the investigation object temporarily with time constants that are larger than a minimum time constant. The investigation object is arranged within the range of a drag axis (4), where roentgen source (1) is swiveled around the drag axis corresponding to discrete deviating method. The roentgen beam has a pass through on the way from roentgen source to the roentgen detector (2). The deviating method has a repetition frequency following one another, which is twice large than the reciprocal value of the minimum time constant. Independent claims are also included for the following: (1) an analysis method for projection data records of an investigation object (2) a data storage medium (3) a computer with a mass storage (4) a roentgen assembly.
