Verification of geometry reconstruction and dose calculation modules of the PLATO radiotherapy planing system
open access
Abstract
Purpose
Verification of reconstruction of application geometry and of calculations of dose distribution in the PLATO v. 13.7 system for brachytherapy treatment planning.
Materials and methods
The correctness of geometry reconstruction was verified using a Perspex phantom with lead markers. Dose calculations were verified by comparing values calculated by the system against values calculated „manually” and against published benchmark values.
Results
The average difference between marker co-ordinates in the phantom, as measured mechanically, and as reconstructed by the PLATO system, did not exceed 0.4 mm. The maximum relative difference between values of dose at given points, calculated by the PLATO system and values of dose calculated „manually” at those points, did not exceed 0.3%. The PLATO system was found to correctly reproduce the published benchmark data.
Conclusions
The geometry reconstruction software module unit and the dose distribution algorithm of the PLATO v. 13.7 planning system used at the Centre of Oncology in Kraków, were found to operate correctly.
