Analysis of intra-fraction prostate motion and derivation of duration-dependent margins for radiotherapy using real-time 4D ultrasound [0.03%]
基于实时4D超声的前列腺肿瘤自由呼吸放疗期间的体内运动分析及动态补偿边距的研究
Eric Pei Ping Pang,Kellie Knight,Qiao Fan et al.
Eric Pei Ping Pang et al.
Background and purpose: During radiotherapy, prostate motion changes over time. Quantifying and accounting for this motion is essential. This study aimed to assess intra-fraction prostate motion and derive duration-depend...
Assessment of leakage dose in vivo in patients undergoing radiotherapy for breast cancer [0.03%]
乳腺癌放射治疗患者皮肤漏射剂量的在体测量评估研究

Peta Lonski et al.
Background and purpose: Accurate quantification of the relatively small radiation doses delivered to untargeted regions during breast irradiation in patients with breast cancer is of increasing clinical interest for the p...
A multi-center output factor intercomparison to uncover systematic inaccuracies in small field dosimetry [0.03%]
多中心输出因子比较研究以发现小射野剂量学的系统偏差
Stefania Clemente,Laura Masi,Christian Fiandra et al.
Stefania Clemente et al.
Large uncertainties in output factor (OF) small fields dosimetry motivated multicentric studies. The focus of the study was the determination of the OFs, for different linacs and radiosurgery units, using new-generation detectors. Intercomp...
A systematic review and meta-analysis of radiotherapy planning studies comparing multi leaf collimator designs [0.03%]
调强放射治疗临床优势的系统评价和荟萃分析——动态MLC与静态MLC计划的比较
Marco Luzzara,Luigi Santoro,Kevin Brown
Marco Luzzara
Background and purpose: Several studies have investigated multi leaf collimator (MLC) leaf design. We performed a systematic review and meta-analysis of those studies to compare the impact of MLC leaf width used for diffe...

Novel methodologies for dosimetry audits: Adapting to advanced radiotherapy techniques [0.03%]
新型剂量学核查方法学：适应先进放疗技术
Marlies Pasler,Victor Hernandez,Núria Jornet et al.
Marlies Pasler et al.
With new radiotherapy techniques, treatment delivery is becoming more complex and accordingly, these treatment techniques require dosimetry audits to test advanced aspects of the delivery to ensure best practice and safe patient treatment. ...
