Abstract
For improved temperature-dependent correction, a method is provided for compiling a temperature-adjusted correction image for the electronic correction of a raw X-ray image recorded by an X-ray detector at a recording temperature. In at least one embodiment, the temperature-adjusted correction image, in particular the temperature-adjusted gain correction image, is generated by numerical calculation from at least one correction image which was recorded at a temperature differing from the recording temperature. In the event of a difference between the recording temperature and the temperature or temperatures for which recorded correction images are available, the raw X-ray image is corrected electronically by use of the temperature-adjusted correction image.
Claims21
A method for generating a temperature-adjusted correction image for electronic correction of a raw X-ray image recorded using an X-ray detector at a recording temperature, the method comprising:
- generating the temperature-adjusted correction image by numerical calculation from at least one correction image which was recorded at a temperature differing from the recording temperature.
An X-ray system comprising:
- an X-ray detector, including at least one temperature sensor, to record a raw X-ray image at a recording temperature;
- and
- an image processing unit to generate a temperature-adjusted correction image by numerical calculation from at least one correction image recorded at a temperature differing from the recording temperature, and to correct the raw X-ray image electronically with the temperature-adjusted correction image.
A method, comprising:
- recording an X-ray image at a recording temperature;
- and
- generating a temperature-adjusted correction image by numerical calculation from at least one correction image, recorded at a temperature differing from the recording temperature.
An X-ray system comprising:
- means for recording a raw X-ray image at a recording temperature;
- and
- means for generating a temperature-adjusted correction image by numerical calculation from at least one correction image recorded at a temperature differing from the recording temperature, and for correcting the raw X-ray image electronically with the temperature-adjusted correction image.
