Abstract:
1. A method for reconstruction of image data of an examination object from measurement data, wherein the measurement data for a relative rotational movement between a radiation source of a computed tomography system and the examination object are recorded, the method comprising: reconstructing first image data with a first image characteristic and second image data with a second image characteristic from the measurement data, a signal-to-noise ratio of the second image characteristic being relatively enhanced as compared to the first image characteristic; and calculating enhanced image data using the first and the second image data and using an iterative algorithm, wherein in the iterative algorithm, a low pass filter is applied to a difference between the first image data and image data of an iteration cycle, and a high pass filter is applied to a difference between the second image data and the image data of the iteration cycle.
