BED Calculator
Calculate Biologically Effective Dose (BED) and Normalized Total Dose (NTD)
Radiobiological Formula: $\text{BED} = D \times \left(1 + \frac{d}{\alpha/\beta}\right)$, where $D$ is total dose, $d$ is dose per fraction, and $\alpha/\beta$ is tissue ratio (typically 3 Gy for late-responding tissues, 10 Gy for tumors). Enter your radiotherapy parameters below.
