Review momentum
20/100
faster than 0% of Medical apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About LQCalc
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。
