Kilovoltage stereotactic radiosurgery for age-related macular degeneration: Assessment of optic nerve dose and patient effective dose
Typical retinal geography highlighting the optic disc, fovea, geometric axis, and foveal offset of the eye.
University of Florida NURBS (A) male and (B) female head models based on organ masses listed in ICRP Publication 89.
Dimensions (in mm) of the tissues structures in the NURBS eye model.
(A) Coronal view of the posterior of the right eye demonstrating the foveal offset (all dimensions are in mm). (B) Axial view of the poster of the right eye demonstrating the position and rotation of the macula

Male NURBS eye models with five optic nerve variations. The macula target and optic disc are shown within the semitransparent eye model.
DVHs for (A) male mean optic nerve, (B) female mean optic nerve, (C) male sup-lat optic nerve, and (D) male sup-lat optic nerve.
Spatial map of the dose distribution within the reference eye and head model of the adult male.
Comparison of tissue masses in the UF hybrid–NURBS and voxel male head phantoms with those given in ICRP Publication 89 for the reference adult male.
Comparison of tissue masses in the UF hybrid–NURBS and voxel female head phantoms with those given in ICRP Publication 89 for the reference adult female.
Mean and standard deviation for the five optic nerve measurements.
