Abstract

Bei einem bildgebenden Verfahren zur Darstellung von Gelenken in verschiedenen Stellungen, wird das darzustellende Gelenk an einem zu einer Drehbewegung antreibbaren Drehsupport festgelegt und in die gewünschte Position oder über einen definierten Schwenkwinkelbereich verschwenkt und die bildgebenden Sensoren werden bei einer bestimmten Position oder über den gewählten Schwenkwinkelbereich zur Aufnahme von Einzelbildern oder einer Bildsequenz geschaltet.
