Frank Cheau-Feng Lin et al.
Objective.The trend in the medical field is towards intelligent detection-based medical diagnostic systems. However, these methods are often seen as 'black boxes' due to their lack of interpretability. This situation presents challenges in ...
Integrating muscle fiber orientation from visible human data into radiotherapy target volumes [0.03%]
将可见人体数据中的肌肉纤维走向信息整合到放射治疗靶区中
Gregory Buti,Ali Ajdari,Yen-Lin Chen et al.
Gregory Buti et al.
Objective.A major challenge in treatment of tumors near skeletal muscle is defining the target volume for suspected tumor invasion into the muscle. This study develops a framework that generates radiation target volumes with muscle fiber or...
Multivariate signal-to-noise ratio as a metric for characterizing spectral computed tomography [0.03%]
多变量信号噪声比在光谱CT特性分析中的应用研究
Jayasai R Rajagopal,Faraz Farhadi,Babak Saboury et al.
Jayasai R Rajagopal et al.
Objective.With the introduction of spectral CT techniques into the clinic, the imaging capacities of CT were expanded to multiple energy levels. Due to a variety of factors, the acquired signal in spectral CT datasets is shared between thes...
A new approach to combined proton-photon therapy for metastatic cancer patients [0.03%]
用于转移性癌症患者的一种新型质子-光子联合治疗的新方法
Nathan Torelli,Yves Bicker,Louise Marc et al.
Nathan Torelli et al.
Objective.Proton therapy is a limited resource and is typically not available to metastatic cancer patients. Combined proton-photon therapy (CPPT), where most fractions are delivered with photons and only few with protons, represents an app...

Wenchao Du et al.
Reducing the radiation dose leads to the x-ray computed tomography (CT) images suffering from heavy noise and artifacts, which inevitably interferes with the subsequent clinic diagnostic and analysis. Leading works have explored diffusion m...
Influence of anatomical structure on antiscatter grid performance in 2D: application to x-ray angiography and a prototype 29:1 ratio grid [0.03%]
解剖结构对二维防散射栅格性能的影响：在血管造影中的应用以及一种新型29：1比例栅格的验证研究

Objective.A simple, low-cost ripple filter consisting of multiple mesh sheets (mRiFi) was previously developed to reproducibly widen the Bragg peak of heavy-ion beams. To fabricate the mRiFi, the mRiFi parameters such as the wire material, ...
Stopping power and range estimations in proton therapy based on prompt gamma timing: motion models and automated parameter optimization [0.03%]
基于及时伽马射线计时的质子治疗停泊能力和范围估算：运动模型和自动化参数优化
Julius Werner,Francesco Pennazio,Niklas Schmid et al.
Julius Werner et al.
Objective.Particle therapy treatments are currently limited by uncertainties of the delivered dose. Verification techniques like Prompt-Gamma-Timing-based Stopping Power Estimation (PGT-SPE) may allow for reduction of safety margins in trea...
In vivo quantitative SPECT imaging of actinium-226: feasibility and proof-of-concept [0.03%]
体内定量测量锕-226的SPECT影像：可行性与概念验证
Helena Koniar,Luke Wharton,Aidan Ingham et al.
Helena Koniar et al.
Objective.225Ac radiopharmaceuticals have tremendous potential for targeted alpha therapy, however,225Ac (t1/2= 9.9 d) lacks direct gamma emissions forin vivoimaging.226Ac (t1/2= 29.4 h) is a promising element-equivalent matched diagnostic ...
PET quantification performance of the oversize-volume-of-interest approach in the context of tumour dosimetry in radionuclide therapy planning [0.03%]
Oversize-ROI方法在核素治疗计划肿瘤剂量学中的定量性能评估
Noah Leander Hammersen,Walter Jentzen,Florian Stawitzki et al.
Noah Leander Hammersen et al.
Objective: The partial-volume effect (PVE) is an important factor impairing tumour quantification in molecular imaging. The commonly used contour-volume-of-interest (contour-VOI) approach to correct for this effect employ...
