Abstract
The image signal in a radiation imaging system is improved by establishing a scattered radiation signal and subtracting the scatter radiation signal from the detected radiation signal. The scatter radiation signal is established by shielding portions of the detector and measuring radiation at the shielded portions of the detector. The total scatter radiation signal is interpolated from spatial distribution of the radiation measured at the shielded areas.
