US 12,517,270 B2 · Method for determining the quality of an imaging plate and imaging plate scanner therefor

Abstract

The invention relates to a method for determining the quality of an imaging plate, comprising the steps of carrying out an exposure of the imaging plate, carrying out a scan of the imaging plate in order to determine an image, determining a signal-to-noise ratio of the image or/and carrying out edge recognition on the image and calculating a quality value of the imaging plate on the basis of the signal-to-noise ratio of the image or/and on the basis of the recognized edge structure. Furthermore, the invention relates to an imaging plate scanner for carrying out such a method.

Dependent claims

A method for determining quality of an imaging plate, the method comprising:

carrying out an exposure of the imaging plate;
carrying out a scan of the imaging plate in order to determine an image;
removing markings from the image to generate a preprocessed image;
adding an unsharpness to the preprocessed image to form an unsharpness preprocessed image;
carrying out an edge recognition on the unsharpness preprocessed image to form an edge recognition preprocessed image;
converting the edge recognition preprocessed image into a binary image by means of a threshold value operation;
and
calculating a quality value of the imaging plate on the basis of the binary image.

5 more elements

An imaging plate scanner comprising:

an imaging plate configured to be exposed;
the scanner configured to carry out a scan of the imaging plate in order to determine an image;
and
a processor, the processor configured to perform the steps comprising:
removing markings from the image to generate a preprocessed image;
adding an unsharpness to the preprocessed image to form an unsharpness preprocessed image;
carrying out an edge recognition on the unsharpness preprocessed image to form an edge recognition preprocessed image;
converting the edge recognition preprocessed image into a binary image by means of a threshold value operation;
and
calculating a quality value of the imaging plate on the basis of the binary image.
