IntroductionOcular proton therapy (OPT) for the treatment of uveal melanoma has a long and remarkably successful history. This is despite that, majority patients treated, definition eye anatomy based on simplified geometrical model embedded in planning system EyePlan. In this study, differences anatomical tumor structures from EyePlan, those 1.5T magnetic resonance imaging (MRI) are assessed.Ma...

PURPOSE To compare gamma knife treatment plans that use skull scaling instrument measurements for skull definition vs. CT based skull definition. METHODS Eight previously treated patients who had head CT scans were randomly selected. Their CT images were imported into Leksell GammaPlan. For each patient, three dose plans were developed: 1. the reference plan. It was planned based on the stand...

The usual definition of the prior(post) interaction V (V ′) between projectile and target (resp. ejectile and residual target) being contradictory with full antisymmetrization between nucleons, an explicit antisymmetrization projector A must be included in the definition of the transition operator, T ≡ V ′ A + V ′ AGV. We derive the suitably antisym-metrized mean field equations leading to a no...

BACKGROUND The shift from conventional two-dimensional (2D) to three-dimensional (3D)-conformal target definition and dose-planning seems to have introduced volumetric as well as geometric changes. The purpose of this study was to compare coverage of computed tomography (CT)-based breast and boost planning target volumes (PTV), absolute volumes irradiated, and dose delivered to the organs at ri...
