Patent ID: 8509379

Claim:
A method to adapt a width and a position of a central value of greyscale windowing for imaging with an x-ray device, comprising: providing a processor with computed tomography (CT) values acquired with an x-ray device having an x-ray tube operated with an acquisition tube voltage to generate said CT values, said processor being programmed to implement a program greyscale windowing algorithm that assumes a reference tube voltage of said x-ray tube of said x-ray device and that associates a width and a position of a central value of said greyscale windowing with said reference tube voltage; in said processor, automatically adapting said programmed greyscale windowing by automatically changing the width and the position of the central value of the greyscale windowing associated with said reference to voltage to a different width and a different position of a central value of the greyscale windowing that are associated with said acquisition tube voltage, to produce an adapted greyscale windowing algorithm; and in said processor, greyscale windowing said CT values using said adapted greyscale windowing algorithm, to generate greyscale windowed CT values, and making said greyscale windowed CT values available at an output of said processor in a form for reconstructing an image using said greyscale windowed CT values.
