First in situ TOF-PET study using digital photon counters for proton range verification.
Positron emission tomography (PET) is the imaging modality most extensively tested for treatment monitoring in particle therapy. Optimal use of PET in proton therapy requires in situ acquisition of the relatively strong (15)O signal due to its relatively short half-life (~2 min) and high oxygen content in biological tissues, enabling shorter scans that are less sensitive to biological washout. ...

متن کاملTime-resolved imaging of prompt-gamma rays for proton range verification using a knife-edge slit camera based on digital photon counters.
Proton range monitoring may facilitate online adaptive proton therapy and improve treatment outcomes. Imaging of proton-induced prompt gamma (PG) rays using a knife-edge slit collimator is currently under investigation as a potential tool for real-time proton range monitoring. A major challenge in collimated PG imaging is the suppression of neutron-induced background counts. In this work, we pr...
متن کاملDesign of practical proton-activated implantable markers for proton range verification using PET
Specific Aims: The aim of this research project is to develop a fiducial marker that can be used for in vivo proton range verification following proton therapy. Our group has previously shown the feasibility of using novel elements as proton-activated fiducial markers that can be imaged using an off-site PET scanner (Cho et al 2013). In this research, we will investigate the optimal physical co...
متن کاملIn vivo proton beam range verification using spine MRI changes.
PURPOSE In proton therapy, uncertainty in the location of the distal dose edge can lead to cautious treatment plans that reduce the dosimetric advantage of protons. After radiation exposure, vertebral bone marrow undergoes fatty replacement that is visible on magnetic resonance imaging (MRI). This presents an exciting opportunity to observe radiation dose distribution in vivo. We used quantitat...
