Image Generating Apparatus, Radiation Tomography Imaging Apparatus, and Image Generating Method and Program

摘要

[Problem] To further reduce artifacts of a reconstructed image. [Solution] Provided is an image generating apparatus which includes: a determining unit configured to determine projection data collected by scan of an imaging object using a radiation source and a detector; a first setting unit configured to set a plurality of first reconstruction planes corresponding to images to be supplied to an operator, in the body axis direction of the imaging object; a second setting unit configured to set one or more second reconstruction planes corresponding to one or more images not to be supplied to the operator and different from the first reconstruction planes, in the body axis direction; a reconstruction unit configured to reconstruct a plurality of images corresponding to the plural first reconstruction planes and images corresponding to the one or more second reconstruction planes, based on the projection data; and a processing unit configured to perform an artifact reduction process on an image corresponding to a given first reconstruction plane using a plurality of images corresponding to a plurality of reconstruction planes including the plural first reconstruction planes and at least one of the one or more second reconstruction planes.
