Abstract

A method compensates for image artifacts in a first imaging device for imaging a first subregion of a body. The image artifacts are caused by a second subregion of the body being disposed outside of a first field of view for the first device. First measured data for the first field of view is acquired by the first device. The first subregion lies in the first field of view. Second measured data are acquired for a second field of view in a second imaging device. Image data representing the subregions in the second device are calculated from the second measured data. A model representing the subregions is calibrated using the calculated image data. The data representing the second subregion in the first device are simulated using a calibrated model. A correction of the first measured data is performed using simulated data for reducing the image artifacts.
