iLQ

iLQ is a radiotherapy dose-equivalence calculator based on the linear-quadratic (LQ) model, designed by radiation oncologists. DESIGNED FOR iPhone Duo Unfolded, iLQ uses both sides of the fold: inputs on one side, the result on the other, always in view. In Information, the list stays on one side and the text opens on the other. TWO CALCULATORS • Equivalent dose: converts a total dose delivered with one dose per fraction into the equivalent total dose for a new dose per fraction. • EQD2: equivalent dose in 2 Gy fractions. FEATURES • 17 organs at risk with their α/β ratio and dose constraint, or any α/β ratio from 0.5 to 20 Gy • Results update as you type • Warnings when the dose per fraction is outside the model's range (1–6 Gy) or when the organ's dose constraint is exceeded • Formulas, LQ model background and conditions of use included • Also runs on Mac with Apple silicon • Works offline, no account, no data collected iLQ is intended for research purposes only. It must not be used to adapt or modify patient treatment.
