Proton head-and-neck (HN) patients often experience target volume changes. Our investigation of daily CBCTs showed the changes from swelling to shrinkage happening usually within one week. Offline adaptation takes about one week to create a replan and thus ve...
To simulate, using Geant4-DNA, proton radiation induced plasmid DNA fragmentation in the plateau as well as Bragg peak regions in a cell-free, aqueous environment of different free radical scavenger concentrations. Atomic Force Microscopy (AFM) measured DNA f...
ZAP-X is a self-shielded radiosurgery system featuring a compact gyroscopic gantry design with kV imaging for patient setup and tracking. Its well-engineered treatment table and treatment-planning system allow lesions located inferiorly to remain treatable. H...
Supercoiled plasmid DNA is widely used to study radiation-induced DNA damage. High-resolution atomic force microscopy (AFM) measurements of radiation-induced DNA fragment-length distributions have directly provided quantitative insights into radiation effects...
