![]() ![]() This study also used a radiophotoluminescent glass dosimeter coupled with an anthropomorphic phantom to evaluate the accuracy of the dose given by CyberKnife. A Monte Carlo simulation for dose verification was performed using BEAMnrc to verify the measured results. A radiophotoluminescent glass dosimeter, thermoluminescent dosimeter, and Kodak EDR2 film were used to measure the lateral dose profile and percent depth dose of CyberKnife. A radiophotoluminescent glass dosimeter was used to verify the dose accuracy for the CyberKnife procedure and validate a viable dose verification system for CyberKnife treatment. ![]() Due to the nature of CyberKnife and the characteristics of SRS, dose evaluation of the CyberKnife procedure is critical. Hsu, Shih-Ming Hung, Chao-Hsiung Liao, Yi-Jen Fu, Hsiao-Mei Tsai, Jo-TingĬyberKnife is one of multiple modalities for stereotactic radiosurgery (SRS). Although TMR 10 algorithm predicts the target dose.« lessįeasibility Study on Applying Radiophotoluminescent Glass Dosimeters for CyberKnife SRS Dose Verification Conclusion: The study shows that dosimetrically comparable plans are achievable with Cyberknife and GammaKnife. For gammaknife treatment plans, the gamma analysis passing rates were 98.9% and 93.2% for target and peripheral region of target respectively. For cyberknife treatment plans, the gamma analysis passing rates between measured and calculated dose distributions were 99.2% and 96.7% for target and peripheral region of target respectively. Results: The dose distribution in the target and 2 cm beyond the target edge were calculated on TPSs and measured using EBT3 film. The measured and calculated doses were compared. Dose distribution were measured using EBT3 film dosimeter. Films were scanned 48 hours after irradiation using an Epson 1000XL flatbed scanner. Using the same film batch, the net OD to dose calibration curve was obtained using both machine by delivering 0- 800 cGy. The treatment planning for the same target weremore » also done for Cyberknife M6 machine using Multiplan (TPS) with Monte Carlo algorithm. The dose distribution were calculated using TMR 10 algorithm. ![]() Methods: Treatment plannings were done for GammaKnife perfection unit using Gammaplan treatment planning system (TPS) on the CT scan of head and neck randophantom simulating the treatment of sterotactic treatments for one brain metastasis. ![]() In this study, the dosimetric comparison of GammaKnife perfection and Cyberknife M6 treatment plans were made. Purpose: Brain stereotactic radiosurgery (SRS) involves the use of precisely directed, single session radiation to create a desired radiobiologic response within the brain target with acceptable minimal effects on surrounding structures or tissues.
