Method of image registration and medical image data processing apparatus

Computer program product, in particular digital storage medium, comprising program means for registration of at least first image data and second data, the program means being adapted to perform the steps of:

• storing of a selection of sub-volumes of the first and second image data,
• performing a registration for each one of the sub-volumes, each registration providing a transformation parameter set,
• performing a global registration for the first and second image data, the global registration providing a global transformation parameter set,
• comparing one of the transformation parameter sets to other transformation parameter sets and/or to the global transformation parameter set for identification of an outlier transformation parameter set of the transformation parameter sets,
• outputting of a signal being indicative of the sub-volume of the outlier transformation parameter set.

A medical image data processing apparatus comprising:

• a memory for a storage of at least first and second image data,
• means for selecting of sub-volumes of the first and second image data,
• means for performing a registration for each one of the sub-volumes and for a global registration of the first and second image data, each registration providing a transformation parameter set,
• means for identification of an outlier transformation parameter set of the transformation parameter sets on the basis of the transformation parameter sets,
• means for outputting of a signal being indicative of the sub-volume of an identified outlier transformation parameter set.
