Abstract

The invention relates to a method for computed tomography imaging. The method includes provisioning a CT data set (D) of an object (O), the CT data set being previously recorded via a multispectral recording method; suppressing a contrast, caused by a tissue type (G1, G2), and generating a contrast-suppressed data set (D) from the CT data set provisioned; and analyzing at least the contrast-suppressed data set(K) generated or a data set(D) generated via a machine learning algorithm based on the contrast-suppressed data set (K), the analyzing being configured to identify at least one change inthe tissue type (G1, G2). A corresponding device, a control device (10) for a computed tomography system or a diagnosis system, and a diagnosis system and a computed tomography system (1) are also disclosed.

Description

technical field

[0001] The present invention relates to a method and apparatus for imaging in computed tomography, and in particular to a method and apparatus for identifying and analyzing different tissue components by utilizing multispectral (photon counting) data recording in combination with iterative data reconstruction and artificial intelligence. Methods for the quantitative assessment of components, especially in the case of cerebral ischemia, to predict the benefit of various treatments. Here, the invention is used for imaging, which means that the invention can be directly applied in the field of image reconstruction, the invention can be used to process the reconstructed image, or can generate in addition to the original data set in the preparatory stage of reconstruction Additional data or additional data about the original dataset. Background technique

[0002] To date, it has not been possible to satisfactorily represent all areas of the human body with an app...
