VERFAHREN UND ANORDNUNG ZUR ERMITTLUNG DER VERTEILUNG DER ABSORPTION EINES KOERPERS

摘要

Artifacts may be produced when a body moves relative to a CT scanner during measurement. Such artifacts are avoided by shifting the measuring values relative to their coordinates as though they were obtained from a non-moving body. The weighted-mean point is determined for each series of measuring values for each specific orientation of the measuring beams. The distance to a point of the image plane is subsequently determined for all weighted-mean lines which pass through said weighted-mean point perpendicular to the measuring coordinates. Next, the measuring values are then shifted or processed in a shifted manner in conformity with said distance.
