摘要： The present invention relates to a device and method for registration of two images. To increase the accuracy of the registration the device comprises an input unit (126) for receiving one or more pairs of negative landmarks, which are indicated in the two images, a pair comprising two negative landmarks, one in each image, which structures are not identical and should not be aligned by the registration. Further, a registration unit (128) is provided for performing a registration of the two images by determining a transformation for transforming at least one of the images for registering it with the other image and determining a spacing measure of the distance between a first landmark in the transformed image and a second landmark in the other image, wherein the transformation is determined such that the spacing measure for a first landmark and a second landmark of at least one pair of negative landmarks is above a first distance threshold, whereby the negative landmarks are taken into account in the registration but are not aligned by the registration.

摘要： The invention relates to a method and an image processing device (50) for the registration of two images(I 1 , I 2 ) that may for example be provided by a CT scanner (10) and/or an MRI scanner (20). According to one embodiment of the invention, the images are first globally registered (GR) with a given registration algorithm using a first parameter vector ( p 0 ). A user may then select a region of interest ROI, and a plurality of local registrations (LR1,... LRs,... LRn) are calculated for this ROI using the same registration algorithm but different parameter vectors( p 1 , p 2 , … p n ). The results of the local registrations (LR1,... LRs,... LRn) are displayed and the user can select the best local registration(s). In a final step, the selected local registration(s) (LRs) and the global registration (GR) may be merged. Additionally or alternatively, a parameter vector for a local registration in the ROI may be determined by an automatic analysis of the ROI.

摘要： The invention relates to an apparatus (18) for calculating an x-ray dose distribution within an object for a computed tomography examination. A primary flux determination unit (15) determines firstly a primary flux distribution within the object, wherein then this determined primary flux distribution is used as an initial total flux distribution by a total flux determination unit (16) while applying a six- flux model algorithm. This allows the determination of the total flux distribution to start with a relatively good first approximation of the total flux distribution such that the six- flux model algorithm can determine the total flux distribution very fast. The determined total flux distribution is finally used by a dose distribution determination unit (17) for determining a total dose distribution. The apparatus allows therefore for a very fast determination of x-ray dose distributions for computed tomography examinations.
