Correcting different conversion characteristics of image sensors involves transforming secondary image signals using inverse characteristics determined using calibration measurements

摘要

The method involves image sensors producing primary image signals from received radiation with first image characteristics, feeding primary image signals from several sensors to a common processing arrangement with a second non-linear characteristic to produce corresponding secondary image signals, determining inverse characteristics from calibration measurements and transforming secondary image signals using the inverse characteristics. The method involves the image sensors producing primary image signals from received radiation with first image characteristics, feeding the primary image signals from several image sensors to a common processing arrangement with a second non-linear characteristic to produce corresponding secondary image signals, determining the inverse characteristics at least approximately from calibration measurements and transforming the secondary image signals using the inverse characteristics. AN Independent claim is also included for the following: an x-ray detector that can implement the inventive method.
