Problems solved by technology

Thus, although an image showing, for example, the patient's anatomy can be shown in the outer subregion of the measurement field, a quantitative analysis of, for example, the material coefficients in the inner subregion of the measurement field is not possible.
As a result, there is no spatially resolved distribution of the material coefficient over the entire measuring field of the dual-source CT system

Embodiment Construction

[0066] figure 1 A dual-source CT system 11 and a computing unit 24 according to the invention are shown. The dual-source CT system is designed to acquire CT measurement data of the patient 13 . The CT measurement data can be transmitted from the dual-source CT system 11 to the computing unit 24 according to the invention, which can acquire the CT image data by means of the acquisition unit of the computing unit 24 and subsequently further process the CT image data.

[0067] The dual-source CT system 11 has a gantry 20 , a tunnel opening 9 , a patient support 10 and a computing unit 24 . The frame 20 has a fixed support frame 21 and a rotating member 24 . The rotary member 24 is arranged on the fixed support frame 21 in a rotatable manner about a rotation axis with respect to the fixed support frame 21 by means of a rotary bearing. A patient 13 can be introduced into the tunnel-shaped opening 9 . The measurement region of the patient 13 can be positioned in the tunnel-shape...

Abstract

The invention relates to a method for providing quantitative CT image data acquired from a measuring field by means of a dual-source CT system, a computing unit for a dual-source CT system, and a dual-source CT system. The method comprises the following method steps: dividing the measurement field into a first measurement field sub-area and a second measurement field sub-area, the first measurement field sub-area is at least a part of the intersection of the first recording area and the second recording area, the second measurement field sub-area and The second recording area is disjoint, the first CT measurement data is acquired from the first measurement field sub-area by means of the dual-source CT device, and the second CT measurement data is acquired from the second measurement field sub-region by means of the dual-source CT device, by means of the first reconstruction method according to The first quantitative CT image data is reconstructed from the first CT measurement data, and the second quantitative CT image data is reconstructed from the second CT measurement data by means of a second reconstruction method, and the first quantitative CT image data and the second quantitative CT image data are synthesized For quantitative CT image data, quantitative CT image data is provided.

Description

technical field [0001] The invention relates to a method for providing quantitative CT image data acquired by means of a dual-source CT system from a measuring field, a computing unit for a dual-source CT system, a dual-source CT system and a computer program product. Background technique [0002] Spectrally resolved CT imaging of the patient (CT-Bildgebung) enables the generation of quantitative CT image data (CT-Bilddaten). Spectrum-resolved CT imaging can be performed, for example, by means of known dual-energy methods or using energy-sensitive detectors. Quantitative CT image data may include information about material coefficients in the patient's body, such as electron density and / or mass density and / or effective nuclear charge number and / or stopping power (Stopping Power) and / or at specific photon energies or at specific photon Information on the position-resolved distribution of the linear attenuation coefficients under the energy spectrum. Instead of a patient, qu...
