What is Methodologies and Tools for Proton Beam Design for Lung Tumors about?

## Purpose: Proton beams can potentially increase the dose delivered to lung tumors without increasing the dose to critical normal tissues because protons can be stopped before encountering the normal tissues. this potential can only be realized if tissue motion and planning uncertainties are correctly included during planning. this study evaluated several planning strategies to determine which method best provides adequate tumor coverage, minimal normal tissue irradiation, and simplicity of use. ## Methods and materials: Proton beam treatment plans were generated using one or more of three different planning strategies. these strategies included designing apertures and boluses to the ptv, apertures to the ptv and boluses to the ctv, and aperture and bolus to the ctv. ## Results: The planning target volume as specified in icru report 50 can be used only to design the lateral margins of beams, because the distal and proximal margins resulting from ct number uncertainty, beam range uncertainty, tissue motions, and setup uncertainties, are different than the lateral margins resulting from these same factors. the best strategy for target coverage with the planning tools available overi
