## LQCalc Description
LQ model (LinearQuadraticModel)に基づき、放射線治療線量の換算計算を行います。HyperFractionation、再照射線量にも対応しています。
1回線量(Gy)、分割回数(Fr)、α/β値から
BED(Biological Effective Dose; 生物学的等価線量) = nd(1 + d/[α/β])
EqD2(Gy等価線量換算値) = 1 回線量 2 Gy換算のnormalized total dose
を計算します。
2種類のα/β値で同時計算が可能です。

本アプリの計算結果は、治療の妥当性や正確性等について保証するものではなく、
一切の責任を負い兼ねます。その結果から生じるいかなる損害についても責任を負いません。あらかじめご了承をお願いいたします。
