| 摘要 |
The present invention relates to a method for the registration and superimposition of image data when taking serial radiographs in medical imaging, wherein a plurality of image data sets for a region of a patient ( 17 ) that is being investigated are constructed at time intervals using an imaging system ( 1 ) and are referenced with a first image data set for the region that is being investigated that was constructed previously using said imaging system ( 1 ). In the above method, a location system ( 2 ) is used during the production of serial radiographs constantly, or at least at a respective proximity in time to the construction of individual data sets, to determine a current spatial position of the region being investigated in a reference system that is firmly connected to the imaging system ( 1 ), whereby in the construction of the first image data set, a first spatial position of the region that is being investigated is recorded. In the construction of some or all further image data sets, the respective current spatial position of the region that is being investigated is determined and an image content of each first image data set is geometrically adapted on the basis of the difference between the first and the current spatial position, such that compensation is made for a different spatial position of the region that is being investigated. The geometrically adapted first image data set or an image data set derived therefrom, or an image data set that is positionally connected thereto by registration is then displayed superimposed with the respective further image data set.
