Automatically obtaining optimized output data

摘要

A method and a system are disclosed for obtaining image data from inside an examination object from images of a computed tomograph. In an embodiment, the method includes accepting first measurement data of the examination object, acquired based on x-ray radiation of a first energy, and second measurement data of the examination object, acquired based on x-ray radiation of a second energy differing from the first energy; setting an optimized output of target image points on the basis of the first and second measurement data at the respective target image points, each as a function of local optimization parameter values of the target image points determined locally from the first and second measurement data in the area of the target image points, while deriving image point reproduction parameter values representing the optimized output; and determining the output data based on optimized output of the target image points.

1. A method for automatically obtaining optimized output data from inside an examination object from images of a computed tomograph, comprising:
accepting first measurement data of the examination object, acquired on the basis of x-ray radiation of a first energy, and second measurement data of the examination object, acquired on the basis of x-ray radiation of a second energy differing from the first energy; setting an optimized output of respective target image points based on the first and second measurement data at respective target image points as a function of respective local optimization parameter values of the respective target image points, each respectively determined locally from the first and second measurement data in the area of the target image points, while deriving image point reproduction parameter values, which each represent the optimized output of the respective target image points; and determining output data on the basis of the optimized output of the target image points.
