Problems solved by technology

[0003] The problem with such systems is that, on the one hand, while CT systems with integrating detectors can be licensed for clinical routine examinations, CT systems with counting detectors are not yet available or only after very cumbersome licensing procedures. such permission

Embodiment Construction

[0029] figure 1 An exemplary CT system 1 is shown with two radiator-detector systems on a gantry (not shown in detail) in a gantry housing 6 . The two radiator-detector systems consist on the one hand of a first X-ray tube 2 and an opposite detector 3 corresponding to the first X-ray tube, and on the other hand of a second X-ray tube 4 and a corresponding detector of the second X-ray tube. The ray tube is composed of relative detectors 5 . The two emitter-detector systems are arranged angularly offset in the plane of rotation on the gantry. According to the invention, the two detectors 3 and 5 can each be equipped with detector elements which differ in their function, so that one detector is designed with counting and the other with integrating detector elements. Alternatively, there is also the possibility of mixing these detectors or at least one detector by forming partially integrating, partially counting detector elements in one detector. For an exemplary division of d...

Abstract

The present invention relates to a computed tomography system (1), including: at least two simultaneously operatable sets of detector elements (I, Z), with at least one first set of integrating detector elements (I) being designed for integrating radiation measurement and at least one second set of counting detector elements (Z) being designed to disperse an incident radiation spectrum into two energy bins; and a computer system (10) for controlling a CT system and at least one capturing for the measurement data of the detector elements with a memory and computer programs contained therein. The computer system (10) is provided with programming so that a first mode is provided for operating only the at least one first set of integrating detector elements (I) and a second mode is provided for the additional or sole operation of the at least one second set of counting detector elements (Z).

Description

technical field [0001] The invention relates to a computed tomography system having at least two groups of simultaneously operable detector elements for simultaneously scanning an examination object from a plurality of different projection angles, wherein at least one integrating detector of the first group The elements are configured for integrated radiation measurement, at least one second set of counting detector elements is configured to decompose the incident radiation spectrum into two energy intervals (Energiebins) and has a computer system for controlling the CT system and For at least one acquisition of measurement data of a detector element, the computer system has a memory and a computer program located therein. Background technique [0002] Such CT systems with simultaneously operable integrating and counting detector element groups are generally known. In this case, a dual-source CT system with two angularly offset detectors is usually constructed, wherein the ...
