Reduction in motion artifacts in nuclear resonance measurements e. g. in medical field involves attaching radiation emitting marker to test object, to detect motion by triangulation using signals from detector pads separated from imagers

摘要

Reduction in motion artifacts during nuclear resonance measurements involves attaching a radiation emitting or reflecting marker (138) to the test object (114) in a test room (112). A radiated beam from the marker is caught by the detector pads (128,130) and imagers (124,126) to detect motion by detector signals and triangulation. The positioning (144), correcting (146) devices are used in the process. Independent claims are also included for: (A) Hollow body with cavity for use as marker; (B) Marker System; (C) Use of marker system; (D) Procedure for reduction or correction of motion artifacts; (E) Computer program; (F) Computer system; and (G) Modulated data signal.
