Abstract:
A Monte Carlo simulation using the PRESTA version of the EGS4 code has been employed as an investigative tool to calculate the absorbed dose in water close to 192Ir wire implants. It has been shown that a treatment planning system, such as GE Target II, using the Sievert integral and the Meisberger polynomial is only able to reproduce the Monte Carlo results at radial distance of 1 mm and farther away. The Sievert integral used with the Meisberger polynomial is proven to be in good agreement with the Monte Carlo generated data at distances between 1 mm and 1 cm.
