Abstract

Die Erfindung betrifft eine Vorrichtung zur Durchfüh­rung eines tomographischen Verfahrens, insbesondere zur Durchführung einer Einzelphotonen-Tomographie, mit min­destens einem Multi-Loch-Kollimator und mindestens ei­nem Detektor zur Erfassung von Photonen, die durch den Mutli-Loch-Kollimator hindurchtreten. Sie ist dadurch gekennzeichnet, dass sie Mittel aufweist, die eine Translationsbewegung relativ zwischen einem zu untersu­chendem Objekt und dem oder den Detektoren mit einer Positioniergenauigkeit kleiner als 1 Millimeter ermög­lichen. Der während der Durchführung des Verfahrens veränderte Position relativ zwischen Objekt und Detektor(en) mit einer Genauigkeit von kleiner als 1 Millimeter, insbe­sondere mit einer Genauigkeit kleiner als 0,1 Millime­ter wird im anschliessenden Rekonstruktionsverfahren be­rücksichtigt. Hierzu wird ein Rekonstruktionsverfahren verwendet, gemäss dem Positions- und Winkelangaben zwi­schen Detektor und Objekt berücksichtigt: werden. Das Verfahren ist auf einem gängigen PC steuerbar und kann auch auf einem solchen ausgeführt werden.
