METHOD AND DEVICE FOR GENERATING A THREE-DIMENSIONAL IMAGE OF AN OBJECT

摘要

The invention relates to a method and a device for generating a three-dimensional image of an object, said device comprising a movable radiation source, a radiation detector, and an analyzing unit. The radiation source is moved relative to the object to be imaged into multiple positions in a first movement on a first track which lies on a first plane in order to capture images, at least one image being captured in each said position. The three-dimensional image is reconstructed from the captured images by the analyzing unit. The radiation source and the radiation detector carry out a second movement relative to the object to be imaged on a second track which is at least partly different from the first track at the same time as the first movement in order to reduce artifacts in the image, said artifacts being generated due to radiation absorption. In the process, the first movement and the second movement are superimposed.

1. A method for producing a three-dimensional image of an object by way of an imaging device, the method comprising:
obtaining or providing or using a movable beam source, obtaining or providing or using a beam detector and obtaining or providing or using an evaluation unit, wherein the beam source for picture recording is moved relative to the object to be imaged, on a first path lying in a first plane, in a first movement into several positions, in which at least one picture is recorded in each case, wherein the three-dimensional image is reconstructed from the recorded pictures by way of the evaluation unit, wherein for reducing an artefact in the image and which is produced by a shadowing, the beam source simultaneously to the first movement carries out a second movement relative to the object to be imaged, on a second path which at least in sections is different to the first path, and wherein the first movement and the second movement superimpose and a distance between the beam source and the object to be imaged during the superposition of the first movement and the second movement is constant.
