Zusammenfassung
Ziele: To design and to evaluate a framework allowing for software based, highly accurate registration of PET and MRI nearly whole-body imaging (from scull base to inguinal). Methode: A new approach to sequentially rigid and non-rigid registration of PET and MRI nearly whole-body imaging was applied: To determine the respective transformations Trigid and Tnon-rigid, first the CT-part of the PET/CT was registered at the MRI. Second the corresponding registration of PET and MRI was achieved by application of (Tnon-regid * Tregid) at the PET-part of the PET/CT. To avoid unnecessary miss-registration in the raw scan…
