Abstract

The present invention relates to a device and to a method for reducing in particular position-related gray value variations of image data sets of an object (18), in particular of a heart, which are recorded in various first layers (SA1, SA2, . . . , SAn) as respective first pictures (SP1, SP2, . . . , SPn) and in at least one second layer (LA1) intersecting with at least one first layer (SA1, SA2, . . . , SAn) as a respective second picture (LP1), comprising the following steps:

registering the respective first pictures (SP1, SP2, . . . , SPn) of the first layers (SA1, SA2, . . . , SAn) relative to each other and with the at least one second picture (LP1) of the at least one second layer (LA1) in order to associate the first pictures (SP1, SP2, . . . , SPn) and the at least one second picture (LP1) of the object (18) with each other, andadjusting respective gray values of the object (18) in the at least one second picture to the respective gray values of the object (18) in the first pictures (SP1, SP2, . . . , SPn) based on a reference-oriented adjustment scheme, wherein the reference-oriented adjustment scheme especially considers or is limited to the intersection area of the respective first picture (SP1, SP2, . . . , SPn) with the at least one second picture (LP1).
