Abstract
A method for reading out image information stored in a storage phosphor of a storage medium includes moving a light beam over the storage medium. A luminescence signal is generated by the photostimulation of the storage phosphor. In first time intervals a respective output value is determined from the luminescence signal, and a respective pixel value of an image pixel of a digital image is determined from the output value. The output value is thereby determined by addition of a plurality of measurement values of the luminescence signal which are detected in second time intervals lying within the first time interval. A corresponding apparatus for carrying out the method is described as well.
Claims19
A method of reading out image information stored in a storage phosphor of a storage medium, the method which comprises:
- a) moving a light beam over the storage medium in order to generate a luminescence signal by photostimulation of the storage phosphor;
- b) within first time intervals, determining a respective output value from the luminescence signal;
- and
- b1) thereby determining the output value by addition of a plurality of measurement values of the luminescence signal taken during second time intervals lying within the first time interval;
- and
- c) determining from the output value a respective pixel value of an image pixel of a digital image stored on the storage medium.
An apparatus for reading out image information stored in a storage phosphor of a storage medium, the apparatus comprising:
- a photostimulation device for photostimulating the storage phosphor and generating a luminescence signal;
- a measuring device configured for detecting the luminescence signal and outputting a measurement value;
- and
- a summation element for determining a respective output value by adding a plurality of measurement values.
