Purpose: Feasibility of silica-based dosimeters for IVD of HDR prostate brachytherapy.

Material And Methods: Plastic dosimeter holders and a water-fillable prostate phantom were built in-house. Interstitial prostate brachytherapy and Monte Carlo simulations were performed. The treatment planning, Monte-Carlo simulation, and dosimetry results were compared.

Results: The relative differences between TLD-TPS, TLD-MCNP, and TPS-MCNP were 0.2-6.9 %, 0.5-6.5 %, and 0.6-6.3 %, respectively.

Conclusion: Micro-silica bead dosimeters can perform offline in situ quality assurance in HDR prostate brachytherapy.
