TG-43U1 Parameterization of Elongated RadioCoilTM 103Pd Brachytherapy Sources

Abstract

Recently RadioCoil? 103Pd sources have been introduced for interstitial prostate implants to eliminate problems associated with seed type sources. These sources are available in integral lengths ranging from 1.0 cm to 6.0 cm. Dosimetric characteristics of these sources have been determined following the TG-43U1 recommendations with consideration of our recent publication on the evaluation of 2D anisotropy function for elongated sources. Dosimetric parameters of these sources were determined experimentally in Solid Water? and theoretically using Monte Carlo simulation in Solid Water? and liquid water. As per TG-43U1 protocol, the consensus of these results would be utilized for clinical applications.
