Flag-2 = Trueとした場合、Flag-5 = Falseとなります。
Flag-4 = Falseとした場合、Index-46~Index-60が無視されます。
回転はyz平面で行われます。
Flag-5 = Trueとした場合、Flag-2 = Falseとなります。
simind.iniの内容に依存します。
厚みはIndex-11で指定します。
散乱回数の上限は3ですが、simind.iniを編集することで変更可能です。
Falseとした場合、毎回同じ計算結果が得られることになります。
デバッグなど特定の用途に有用ですが、通常はTrueにするべきです。
coverの断面積はMain-9で指定します。
厚さはIndex-13で指定します。
エネルギー分解能はIndex-22で指定します。
固有空間分解能はIndex-23で指定します。
画像(*.ict)およびヘッダー(*.hct)が出力されます。
ファイルはIndex-11 = Trueおよびvoxel phantomが使用されている(Index-14 = 負の値)場合のみ出力されます。
