Embodiment Construction

[0046] in figure 1 As an example and roughly schematically shows a computer tomography system 1 according to the present invention, which includes a user terminal 25 and a computer tomography device 2. The computer tomography system 1 is configured to execute the image reconstruction method according to the present invention. The computed tomography apparatus 2 includes a patient table 12 for positioning the patient 1 as an examination object, which can be displaced along the system axis 16. The system axis 16 is also denoted as the z-axis hereinafter, which can be displaced into the scanning field with the patient 10. It also includes a stand 3 with a source-detector arrangement 4, 5, which is mounted to be rotatable about the system axis 16. The source-detector arrangements 4, 5 have an X-ray radiation source 5 and a quantum counting detector 4, which are oriented relative to each other so that the X-ray beam emerging from the focal point of the X-ray beam source 5 is incide...

Abstract

The present invention relates to a method based on a first plurality (N) of spectral raw data sets (SD 1 , SD 2 ,..., SD N ), the first plurality (N) sets of spectral raw data are each associated with a different X-ray spectrum. The invention also includes an image reconstruction device (13) and a computed tomography system (1).

Description

Technical field [0001] The invention relates to an image reconstruction method, image reconstruction equipment and a computer tomography system. Background technique [0002] During the projection of the X-ray through the inspection object, different absorption and scattering behaviors occur according to the spectrum used and the material to be penetrated, in which the low-energy component of the absorption spectrum is more than the high-energy component (radiation hardening). fast. Therefore, the X-ray radiation detected behind the inspection object contains information about the material properties of the inspection object. In a computed tomography system (CT system) in which multiple spectra of X-ray radiation are simultaneously detected, after acquiring projection data, it is possible to reconstruct an image data set containing information about materials contained in the inspection object. "Different X-ray energies" should be understood as using different X-ray energy spec...
