Abstract
Accuracy of Clarkson algorithm employed in a commercial 3D TPS was evaluated for conditions simulating tangential breast treatment. A breast phantom was fabricated from machineable wax to examine the accuracy of tangential breast irradiation. This Paper specifically describes the use of unique self-designed wax breast phantom to validate the accuracy of three-dimensional dose calculations performed by Xio-CMS planning system for breast tangential irradiation. Steven et all(1) has done a related study using anthropomorphic breast phantom .In our study the accuracy of dose calculations has been verified using 0.6cc ionization chamber. The treatment plans has been generated using the combined 6 and 15 MV photon beams and field in field technique. Measured doses have been compared to those calculated from the treatment planning system and found to be in good agreement with previously published results. Our results indicates that the inexpensive wax phantom can be used for verification in absence of expensive anthropomorphic breast phantom which may be of great help for verification of 3D breast plans in developing countries.
