Department of Radiology, Children's Hospital, Harvard Medical School, Boston, MA 02115, USA.

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).
