A study on strategies to optimize bladder volume consistency in radiotherapy patients
This study aimed to investigate the impact of multi-step workflow optimization on enhancing the consistency of bladder volume among patients receiving pelvic radiotherapy. Patients requiring bladder preparation were selected through simple random sampling before and after the implementation of optimization measures in June 2024. Each cohort included 5 patients with prostate cancer, 15 with cervical cancer, and 10 with rectal cancer cases. Statistical methods were used to evaluate the correlation and consistency between bladder volume measured by cone-beam CT (V Pearson correlation analysis showed that a strong correlation between V Multi-step workflow optimization reduced the standard deviation of differences between CBCT-derived and scanner-derived bladder volumes (V
