SCATTER CORRECTION BASED ON RAW DATA IN COMPUTER TOMOGRAPHY

摘要

A method is disclosed for reconstructing image data of an object under examination from measured data, with the measured data having been detected beforehand during a relative rotational movement between a radiation source of a computer tomography system and the object under examination. In at least one embodiment, a radiation scatter correction variable is determined, which is subjected to a low pass filtering. The filtered radiation scatter correction variable is connected with the measured data to correct the measured data, and image data is reconstructed from the measured data thus corrected.
