US 11,308,664 B2 · Method for reconstructing a three-dimensional image data set

Abstract

Systems and methods are provided for reconstructing a three-dimensional result image data set from computed tomography from a plurality of two-dimensional images that create an image of an object undergoing examination from a particular imaging angle, The imaging angles of all the images lie within a restricted angular range. A three-dimensional artifact-reduced image data set is provided based on the two-dimensional images using an algorithm for reducing artifacts that are the result of a restriction of the angular range. The result image data set is reconstructed using a reconstruction algorithm that processes both the artifact-reduced image data set and the two-dimensional images as input data.

A method for reconstructing a three-dimensional result image data set from computed tomography from a plurality of two-dimensional images that create an image of an object undergoing examination from a particular imaging angle, the method comprising:

providing a three-dimensional artifact-reduced image data set as a function of the plurality of two-dimensional images, wherein the plurality of two-dimensional images or a processing result that is dependent on the plurality of two-dimensional images are processed by an algorithm for reducing artifacts;
and
reconstructing the three-dimensional result image data set using a reconstruction algorithm that processes using as input data both the three-dimensional artifact-reduced image data set and the plurality of two-dimensional images.
