- We devised a method to allow for retrospective registration of tomographic images with very different information content, the main emphasis being on sets of positron emission tomography images obtained with different tracers. A multivariate cost-function

Tidskriftsartikel (refereegranskat)abstract
- Fully automatic co-registration of functional to anatomical brain images using information intrinsic to the scans has been validated in a clinical setting for positron emission tomography (PET), but not for single-photon emission tomography (SPET). In thi

Improved efficiency for MRI-SPET registration based on mutual information

Ingår i: EUROPEAN JOURNAL OF NUCLEAR MEDICINE. - 0340-6997. ; 27:7, s. 847-856
-
Tidskriftsartikel (refereegranskat)abstract
- Mutual information has been proposed as a criterion for image registration. The criterion is calculated from a two-dimensional grey-scale histogram of the image pair being registered, In this paper we study how sparse sampling can be used to increase spee
