Imaging tomography device with at least two mutually fixedly arranged receiving systems and method for such a tomography device for the determination of the arrangement of the image pick-up systems

摘要

In the case of a tomography device according to the invention (3) with at least one in a first measurement plane (14) arranged receiving system (1.1, 1.2) and a in a second measurement plane (16) arranged receiving system (2.1, 2.2), which in the azimuthal direction about a common axis of rotation (5) are disposed, are the position correction values (k1.1,.. km.n) of the two measurement planes (14, 16) for at least one at least substantially constant angular speed of rotation of the two image pick-up systems (1.1, 1.2, 2.1, 2.2) on the basis of at least at a rotational angle position calculated measured values (m1, α0 or.. m1, αn or m2, α0 or.. m2, αn) of a in the two measurement planes (14, 16) which are placeable reference object (r) can be determined. The tomography device according to the invention (3) in this way permit permit artifact-free reconstruction of a layer - or volume image by taking into account the position correction values (k1.1,.. km.n).
