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 (14), said device comprising a movable radiation source (1), a radiation detector (2), and an analyzing unit. The radiation source (1) is moved relative to the object (14) to be imaged into multiple positions in a first movement (11) on a first track (3) 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 (1) and the radiation detector (2) carry out a second movement (6) relative to the object (14) to be imaged on a second track which is at least partly different from the first track (3) at the same time as the first movement (11) 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.
