A photographic technique for quick assessment of mechanical isocenter of a linear accelerator [0.03%]
一种快速评估直线加速器机械等中心的摄影技术
Janne Heikkilä,Jan Seppälä,Jouni Nuutinen et al.
Janne Heikkilä et al.
Demands for mechanical accuracy of medical linear accelerators are increased due to the stereotactic and modulated rotational treatments. Mechanical inaccuracies affect the size and shape of the mechanical and radiation isocenters. In pract...

Michal Stankiewicz et al.
Purpose: Substantial, unanticipated anatomic variances during cone-beam CT (CBCT)-guided radiotherapy can potentially impact treatment accuracy and clinical outcomes. This study assessed patterns of practice of CBCT varia...
RTT-led IGRT for cervix cancer; training, implementation and validation [0.03%]
自适应实时追踪引导放疗宫颈癌临床实施及验证研究
S E Alexander,N Hopkins,S Lalondrelle et al.
S E Alexander et al.
Introduction: IGRT in cervical cancer treatment delivery is complex due to significant target and organs at risk (OAR) motion. Implementing image assessment of soft-tissue target and OAR position to improve accuracy is re...
Protocolised way to cope with anatomical changes in head & neck cancer during the course of radiotherapy [0.03%]
头颈肿瘤放疗过程中解剖变化的应对流程化方法
Suzanne van Beek,Marcel Jonker,Olga Hamming-Vrieze et al.
Suzanne van Beek et al.
Introduction: During a course of radiotherapy for head-and-neck-cancer (HNC), non-rigid anatomical changes can be observed on daily Cone Beam CT (CBCT). To objectify responses to these changes, we use a decision support s...

单次立体放射治疗肾上腺转移瘤的屏气与中度通气的对比研究
Melissa de Kuijer,Jaap van Egmond,E Kouwenhoven et al.
Melissa de Kuijer et al.
Purpose: To improve local control in radiotherapy of adrenal metastases precise dose delivery without increasing toxicity is vital. Decreasing the Clinical Target Volume (CTV) - Planning Target Volume (PTV) margins by red...
Contrast enhanced oesophageal avoidance for stereotactic body radiotherapy: Barium vs. Gastrografin [0.03%]
立体定向体放射治疗食管避让的对比增强方法：硫酸钡与胃肠造影剂的比较
Katrina Woodford,Vanessa Panettieri,Jeremy D Ruben et al.
Katrina Woodford et al.
Introduction: SABR may facilitate treatment in a greater proportion of locally-advanced NSCLC patients, just as it has for early-stage disease. The oesophagus is one of the key dose-limiting organs and visualization durin...

放射治疗计划中的静脉注射对比剂CT扫描-爱尔兰现行做法
Shane Minogue,Charles Gillham,Maeve Kearney et al.
Shane Minogue et al.
Introduction: While Computerised Tomography (CT) remains the gold standard in radiation therapy (RT) planning, inferior soft tissue definition remains a challenge. Intravenous contrast (IVC) use during CT planning can enh...
