Rapid delivery of radiation therapy is expected to benefit patients requiring palliation. We investigated the feasibility of employing a helical tomotherapy unit to scan, plan, and deliver a radiation treatment in a single radiation therapy appointment. Eleven patients each had an MVCT scan acquired, a plan created, and delivery completed while the patient was on the treatment couch. Timelines for each step of the process were recorded for each patient, and compared with the conventional process for similar patients. Preliminary results show that patients routinely can be treated within a 1 hour appointment for the first fraction.
快速放射治疗有望使需要姑息治疗的患者受益。我们研究了使用螺旋断层放射治疗设备在单次放射治疗预约中进行扫描、计划制定和放射治疗的可行性。11名患者在治疗床上时均完成了MVCT扫描、计划制定和放射治疗。记录了每位患者治疗过程中每个步骤的时间线，并与类似患者的传统治疗过程进行了比较。初步结果表明，患者通常可以在1小时的首次治疗预约时间内完成治疗。
