title = "A new non-uniformity response correction method of X-ray real time imaging system",
abstract = "For the X-ray real time imaging system base on image intensifier, the non-uniformity response among each pixel channel can not be ignored, which cause the fixed pattern noise and degrade the image quality obviously. In order to correct the non-uniformity response, a logarithm response model is created to fit the output-input characteristic curve of each pixel channel, then the correction coefficient table is obtained to make each pixel channel has the same response sensitivity. In practical application, the un-corrected image is divided by the correction coefficient table to get rid of the fixed pattern noise. The experimental results prove that the algorithm has an efficiency of real time correction and the corrected image quality can be increased effectively.",
