The total absorbed dose delivered by the reference treatment plan (fraction size [math]X[/math]) that leads to the same biological effect as a test treatment plan that is conducted with absorbed dose per fraction [math]d[/math] and total absorbed dose [math]D[/math] according to the relation:
[math] EQDX_{\alpha/\beta} = D \cdot \frac{d+\alpha/\beta}{X + \alpha/\beta} [/math]
where [math]\alpha/\beta[/math] is an endpoint- and radiation quality-specific parameter that describes the effect of changes in dose per fraction.
