Embodiment Construction

[0046] figure 1 A flowchart 100 is shown, which shows a dynamic CT imaging method by means of the so-called dual-energy technique according to an exemplary embodiment of the invention, in which contrast-enhanced image data is generated from obese patients. In the dynamic imaging method by means of the dual-energy technique, a dynamic time-resolved acquisition of two projection measurement datasets PMD1, PMD2 is performed, each with a different mean energy E 1 ,E 2 by having a different X-ray energy spectrum R E1 , R E2 generated by X-ray radiation. In order to use a different X-ray energy spectrum R E1 , R E2 X-ray radiation is generated, for example two X-ray sources 15a, 15b can be used (see image 3 ), which at different X-ray energies E 1 ,E 2 or X-ray spectroscopy R E1 , R E2 emit X-ray radiation.

[0047] In the context of a dynamic imaging method, in step 1.1 first data relating to the dimensions of the object to be examined (eg a patient) is acquired. This ...

Abstract

An X-ray imaging method (100) is for generating contrast-enhanced image data (BD) relating to an examination region (FOV) of an object (O) to be examined. Perferably a CT-X ray imaging method is disclosed. In an embodiment of the method, first contrast-agent influenced measured X-ray projection data (PMD1) with a first X-ray energy spectrum (RE1) and at least one set of second contrast-agent influenced measured X-ray projection data (PMD2) with a second X-ray energy spectrum (RE2) are acquired from the examination region. Subsequently, image data assigned to a third X-ray energy spectrum with a third mean energy (E3), based on the first and at least second measured X-ray projection data is reconstructed based on the first and at least second measured X-ray projection data that has been acquired. A mean energy of the first X-ray energy spectrum and a mean energy of the second X-ray energy spectrum are selected as a function of a dimension parameter value of the object that is to be examined. The invention also describes an image data generating device (20) and a computer tomography system (1).

Description

technical field [0001] The invention relates to an X-ray imaging method for generating contrast-enhanced image data. The invention also relates to an image data generating device. Furthermore, the invention relates to a computer tomography system. Background technique [0002] With the aid of modern imaging methods, two-dimensional or three-dimensional image data are frequently generated which can be used to visualize the imaged examination object and which can also be used for other applications. [0003] Imaging methods are generally based on the detection of X-ray radiation, where "projection measurement data" are generated. For example, projection measurement data can be acquired by means of a computer tomography system (CT system). In a CT system, the combination of an X-ray source and an X-ray detector arranged opposite said source and arranged on a gantry usually rotates around a measurement space, examining an object (without loss of generality, hereinafter mostly...
