[Comparison of setup errors between two immobilization methods in prostate cancer radiotherapy based on cone-beam computed tomography].

Year: 2025

Type: article

Abstract: OBJECTIVE: . conventional carbon fiber body fixation frame combined with thermoplastic membrane) in radical radiotherapy for prostate cancer, and to calculate the clinical target volume (CTV) to planning target volume (PTV) margin (MPTV) for both methods to optimize immobilization techniques and radiotherapy workflows. METHODS: ). RESULTS: 0.54 cm and 0.42 cm. CONCLUSION: directions compared with the conventional fixator combined with a thermoplastic mask, indicating the need for further workflow optimization. Given that the lithotomy position is essential for transperineal ultrasound-guided techniques, further research and improvements are required to achieve higher positioning accuracy.
