Brent van der Heyden,Lotte E J R Schyns,Mark Podesta et al.
Brent van der Heyden et al.
Background and purpose: Dedicated CT simulation models have the potential to investigate several acquisition, reconstruction, or post-processing parameters without giving any radiation dose to patients. A software program...
Analyses of regional radiosensitivity of white matter structures along tract axes using novel white matter segmentation and diffusion imaging biomarkers [0.03%]
基于新型白质分割和弥散张量影像生物标志物的轴束上白质结构区域性放射敏感性分析
Jordan Houri,Roshan Karunamuni,Michael Connor et al.
Jordan Houri et al.
Background and purpose: Brain radiotherapy (RT) can cause white matter damage and downstream neurocognitive decline. We developed a computational neuroimaging tool to regionally partition individual white matter tracts, t...
Evaluating the repeatability and set-up sensitivity of a large field of view distortion phantom and software for magnetic resonance-only radiotherapy [0.03%]
评价大视场畸变体模及软件的重复性和安装敏感性用于磁共振单模放射治疗
Jonathan Wyatt,Stephen Hedley,Emily Johnstone et al.
Jonathan Wyatt et al.
Background and purpose: Magnetic Resonance (MR)-only radiotherapy requires geometrically accurate MR images over the full scanner Field of View (FoV). This study aimed to investigate the repeatability of distortion measur...
Inter-centre variability of CT-based stopping-power prediction in particle therapy: Survey-based evaluation [0.03%]
基于CT的粒子治疗停药能力预测的中心间差异：基于调查的评估
Vicki T Taasti,Christian Bäumer,Christina V Dahlgren et al.
Vicki T Taasti et al.
Background and purpose: Stopping-power ratios (SPRs) are used in particle therapy to calculate particle range in patients. The heuristic CT-to-SPR conversion (Hounsfield Look-Up-Table, HLUT), needed for treatment planning...
Deriving the mean excitation energy map from dual-energy and proton computed tomography [0.03%]
基于双能和质子CT的平均激发能量图提取
Gloria Vilches-Freixas,Catherine Therese Quiñones,Jean Michel Létang et al.
Gloria Vilches-Freixas et al.
The mean excitation energy, I, is an essential quantity for proton treatment planning. This work investigated the feasibility of extracting the spatial distribution of I by combining two computed tomography (CT) modalities, dual-energy CT a...
Comparison of single and dual energy CT for stopping power determination in proton therapy of head and neck cancer [0.03%]
单能量CT和双能量CT在头颈部癌症质子治疗中的止动功率的比较研究
Vicki Trier Taasti,Ludvig Paul Muren,Kenneth Jensen et al.
Vicki Trier Taasti et al.
Background and purpose: Patients with head and neck (HN) cancer may benefit from proton therapy due to the potential for sparing of normal tissue. For planning of proton therapy, dual-energy CT (DECT) has been shown to pr...
