METHOD FOR GENERATING HIGH RESOLUTION IMAGE OF INCIDENT RADIATION AND RADIATION IMAGING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a method and a device for generating a high resolution image in a radiation imaging system generating multiple irradiation signals from a movable detector array. SOLUTION: An image data signal or an image acquirement signal generated from the image detector assembly 105 of an image radiation system 100 in an imaging cycle is made to pass through a finite impulse response filter 134 having a combined frequency response constituted of an inverse filter frequency response part and a noise normalization frequency response part and the frequency response of the filter is reduced with the increase of the frequency of a data signal by noise normalization. Thus, the image generated from the image data signal is effectively prevented from becoming obscure.
