METHOD FOR RECONSTRUCTION OF AN IMAGE DATASET IN COMPUTER TOMOGRAPHY, COMPUTER TOMOGRAPHY DEVICE, COMPUTER PROGRAM AND ELECTRONICALLY READABLE DATA CARRIER

摘要

Method for the reconstruction of an image data set from projection images of an examination object (10) recorded under different projection directions with a computed tomography device (19), the computed tomography device (19) having a nominal field of view (8) which is captured from all projection directions in the respective projection images, and wherein the examination object (10) and / or an additional object (16) assigned to the examination object (10), in particular its storage, extends partially from the nominal field of view (8) into an expanded field of view (11), one for reconstruction of the image data set determining the contour of the examination object (10) and / or the contour information describing the additional object (16), - the projection data of the projection images based on the contour information by forward projection in areas in which the examination object (10) and / or the additional object (16) are in the Projection ns data of a projection image was not recorded, are supplemented, and - the reconstruction takes place on the basis of the supplemented projection data, at least one camera (26) capturing the examination object (10) positioned to record the projection images and / or the additional object (16) from sensor data Contour of the examination object (10) and / or the additional object (16) at least partially describing sensor information is determined and used to determine the contour information.
