Generalizable dose denoising using diffusion transformer framework for pencil beam scanning proton therapy

Physics and Imaging in Radiation Oncology
Background and purpose: Intensity-modulated proton therapy (IMPT) enables conformal dose delivery for head and neck (H&N) cancers. However, its sensitivity to inter-fractional anatomical changes motivates online adaptations, where rapid and accurate ...

Improving the precision and performance of proton pencil beam scanning

, 2012
In this report we present the technical features of Gantry 2, the new second generation scanning system of PSI. On the basis of the experience and success with the first prototype, Gantry 1, built in the 90s for introducing pencil beam scanning and IMPT into the field of proton therapy, we have recently implemented a new system capable of offering much

Effects of Defining Realistic Compositions of the Ocular Melanoma on Proton Therapy

Journal of Biomedical Physics and Engineering, 2014
Background: Recent studies in eye plaque brachytherapy have shown a considerable difference between the dosimetric results using water phantom and a model of human eye containing realistic materials. In spite of this fact, there is a lack of simulation
