METHOD AND COMPUTER PROGRAM PRODUCT FOR GENERATING AN ARTEFACT REDUCED VOXEL DATA RECORD

摘要

The present invention relates to a method and a computer program product for generating an artefact-reduced voxel data record of an object. The artefact-reduced voxel data record of the object is generated with the aid of a computed tomography scanner. In some aspects of the present disclosure, a first image data record and a second image data record is generated by acquiring computed tomography images of the object. In still other aspects of the present disclosure, the artefact-reduced voxel data record of the object is generated with the aid of an image data reconstruction algorithm.

1. A method for generating an artefact-reduced voxel data record of an object, the method comprising:
generating, by a computing device, a first image data record by acquiring a multiplicity of first computed tomography images of the object, wherein an acquisition angle in respect of a first axis of rotation is modified between the acquisition of the first computed tomography images; tilting the object by a predetermined tilt angle in respect of a second axis of rotation, wherein the second axis of rotation is arranged substantially orthogonal to the first axis of rotation; generating, by the computing device, a second image data record by acquiring a multiplicity of second computed tomography images of the object tilted about the second axis of rotation; utilizing an iterative image data reconstruction algorithm to generate the artefact-reduced voxel data record of the object based on the generated first image data record and the generated second image data record.
