Description

Objective: To study the setup errors of three immobilization methods in thoracic cancer radiotherapy with cone beam CT. Methods: Setup discrepancy in R/L, S/I, and A/P directions were calculated and recorded after CBCT scan with Elekta XVI. Residue errors after correction was recorded with second CBCT scan. Total errors were also calculated. Results: Setup errors were significantly reduced after CBCT correction. Group with thermoplastic frame indicated the least residue setup errors compared to the other two immobilization methods (P = 0.06). Conclusion: Setup correction with CBCT can reduce the setup error dramatically for thoracic cancer radiotherapy. Thermoplastic frame achieved best setup accuracy with CBCT correction. (authors)
