Comparison of gantry-less magnetic resonance guided proton therapy with photon therapy for hepatocellular carcinoma patients. [PDF]

Phys Imaging Radiat Oncol
Background and purpose: With magnetic resonance imaging (MRI), soft-tissue tumors such as hepatocellular carcinoma (HCC) are visualised. MR guided proton therapy (MRgPT) may combine the advantages of proton therapy with soft-tissue image-guidance ...

Optimization of adaptive radiation therapy in cervical cancer: Solutions for photon and proton therapy [PDF]

, 2016
In cervical cancer radiation therapy, an adaptive strategy is required to compensate for interfraction anatomical variations in order to achieve adequate dose delivery. In this thesis, we have aimed at optimizing adaptive radiation therapy in cervical cancer to improve treatment efficiency and reduce radiation-induced toxicities.First, the clinically ...

Experimental validation of daily adaptive proton therapy [PDF]

Physics in Medicine & Biology, 2021
Abstract Anatomical changes during proton therapy require rapid treatment plan adaption to mitigate the associated dosimetric impact. This in turn requires a highly efficient workflow that minimizes the time between imaging and delivery.
