  • Title: Registration and alignment of three-dimensional images: an interactive visual approach.
    Author: Habboush IH, Mitchell KD, Mulkern RV, Barnes PD, Treves ST.
    Journal: Radiology; 1996 May; 199(2):573-8. PubMed ID: 8668816.
    Abstract:
    A three-dimensional registration and alignment algorithm was developed to align single photon emission computed tomography examinations and magnetic resonance images. Operators manipulated images interactively with real-time visual feedback, with use of both internal and surface features to achieve accurate alignment. Operators aligned five brain phantom examinations (accuracy, 1.6 pixels; consistency, 0.7 pixels) and eight patient brain examinations (consistency, 0.5 pixels).
