Brachytherapy seed dose distribution calculation employing the fast Fourier transform

Abstract
A mathematical procedure is described by which the dose distribution of a seed implant can be calculated employing a Fourier transform. The procedure is described in one-, two-, and three-dimensional representations. Dose distributions calculated using this technique are demonstrated. Mathematical constraints of the procedure are discussed.
