Abstract
The radiation image in a radiation imaging system is improved by extracting a scatter distribution and subtracting the scatter distribution from the radiation image. The scatter distribution is extracted from the radiation image by an adaptive filter using a scatter-glare point spread function. The scatter-glare point spread function is obtained by measurements of the radiation system.
