Abstract
A method is described for the determination of patient specific organ beta doses given a known cumulated internal radioactivity distribution . A voxel source kernel for Y-90 analogous to the point source functio n was simulated. Dose to each organ of interest could then be estimate d by convolving the voxel source kernel with the patient's 3-D volume with known radioactivity assigned to each voxel. The dose calculation on eight organs took less than 1 min per patient using a Sun Sparc10 w orkstation. (C) 1998 Elsevier Science Inc.
