Hermanská, M. Kárný] Estimation of the effective half-life, i.e. the time during which the activity within a region of interest falls to half of its original value, is a task often met in nuclear medicine applications. usually, the estimation is based on the least squares (LS) fit of a straight line to the observed data expressed in semi-logarithmic coordinates. Such a solution is susceptible to measurement errors and provides little information on the estimate reliability. The Bayesian solution presented treats this estimation problem in a more efficient way by respecting the well defined probabilistic problem structure and exploiting all information sources available. The efficiency claimed has been verified on a extensive set of real life data related to diagnostics/therapy of thyroid diseases by 131I. An illustrative account of the experiments performed is presented.
