Description
(式3)
で与えられる。αは利得係数をモデル化したものであり、βはオフセット係数をモデル化したものである。これらの係数は基準検出器102及び第一の方向検出器104の実際の実施態様を通じて導入される。諸実施態様において、利得係数αは、1にほぼ等しくてもよく、オフセット係数βは0にほぼ等しくてもよい。実際の実施態様では、放射線検出器は、一般的にこれらの補正係数でモデル化され得るオフセット及び非線形性を示す。オフセット係数βは周囲の放射線を補うために使用されてもよい。
(式4)
で与えられる。幅Dと高さHは既知のパラメータである。利得係数α及びオフセット係数βは、使用される場合には、実験的に決定されてもよい。f1対fmの比率は、基準検出器102及び第一の方向検出器104の出力信号に基づいて計算される。
(式5)
で与えられる。式中、f2は第二の方向検出器106によって提供される放射強度信号である。本例では、入射角φは負角である。
