Architecture of our real-time motion monitoring system (SLIMM). Slices are transferred through SAMBA from the scanner computer to a workstation that runs our algorithm. The slice monitoring module watches the new slice acquisitions and sends the file names of the new slices to the registration server. Motion measurements are conducted by the registration service. The measured transformations (each contains 6 motion parameters) are dispatched to the presentation server and shown by one or more client services.
