Embodiment Construction

[0088] figure 1 A filter device 5 for spectral filtering of the X-ray fan beam 7 of the computed tomography system 1 is shown, the filter device 5 comprising:

[0089] - a first filter area 51 comprising a first spectral filter function,

[0090] - a second filter area 52 comprising a second spectral filter function different from the first spectral filter function,

[0091] - the first filter area 51 and the second filter area 52 are arranged consecutively in a direction perpendicular to the central plane 7C of the X-ray fan beam 7 and adjacent to each other along the dividing line 54,

[0092] - wherein when the filter device 5 is placed in a first position relative to the X-ray fan beam 7, the first filter area 51 covers the first cross-sectional area 71 of the X-ray fan beam 7 and the second filter area 52 covers a second cross-sectional area 72 of the X-ray fan beam 7 .

[0093] The filter unit 5 also includes:

[0094] - a third filter area 53 comprising a second spe...

Abstract

The embodiment of the invention relates to a filter device for X-ray beam spectrum filtering of computed tomography equipment. The present invention relates to a filter device for spectral filtering of an X-ray fan beam of computed tomography equipment, wherein the filter device comprises: a first filter region comprising a first spectral filter function, and a second filter region comprising a second spectral filter function, the second spectral filter function differs from the first spectral filter function, the first filter region and the second filter region are arranged contiguously in adirection perpendicular to a central plane of an X-ray fan beam and adjacent to each other along a parting line, and when the filter device is placed in a first position relative to the X-ray fan beam, the first filter region covers the first cross-sectional area of the X-ray fan beam and the second filter region covers the second cross-sectional area of the X-ray fan beam.

Description

technical field [0001] In one aspect, the invention relates to a filter arrangement for spectral filtering of an X-ray fan beam of a computed tomography system. In another aspect, the invention relates to a computed tomography device. In another aspect, the invention relates to a method for providing spectral computed tomography data using a computed tomography apparatus. In a further aspect, the invention relates to a method for producing a filter arrangement for spectral filtering of an X-ray fan beam of a computed tomography system. In a further aspect, the invention relates to a method for localizing defects in a filter arrangement for spectral filtering of an X-ray fan beam of a computed tomography system. Background technique [0002] Compared to conventional single-energy computed tomography (CT) scanners, spectral computed tomography, such as that in the form of dual-energy spectral computed tomography, allows more precise differentiation of tissue and Chemistry o...
