PROBLEM TO BE SOLVED: To provide radiographic equipment being applicable to a general-purpose scattered radiation removal means and capable of providing an appropriate radiation image independent from the installation state of the scattered radiation removal means.SOLUTION: A pixel specification section 41 specifies predetermined pixels out of respective pixels constituting an X-ray image. An intensity estimation section 44 estimates at least one scattered X-ray intensity (a scattered radiation intensity) at the predetermined pixels specified by the pixel specification section 41 and a direct X-ray intensity (a direct radiation intensity) at the predetermined pixels. This constitution can thus appropriately estimate at least one intensity of the scattered X-ray intensity and the direct X-ray intensity at the predetermined pixels with consideration given to the installation state of the grid (a scattered radiation removal means).COPYRIGHT: (C)2009,JPO&INPIT【課題】汎用の散乱放射線除去手段にも適用することができ、散乱放射線除去手段の設置状態に依存せずに、適切な放射線画像を得ることができる放射線撮像装置を提供することを目的とする。【解決手段】X線画像を構成する各々の画素のうち、所定の画素を画素特定部41は特定する。その画素特定部41で特定された所定の画素での散乱X線強度(散乱線強度)、所定の画素での直接X線強度(直接線強度)の少なくとも1つの強度を強度推定部44は推定する。したがって、グリッド(散乱放射線除去手段)の設置状態が考慮された所定の画素での散乱X線強度、直接X線強度の少なくとも1つの強度を適切に推定することができる。【選択図】図4
