An Empirical Model for Describing the Small Field Penumbra in Radiation Therapy
Purpose. We developed a mathematic empirical model for describing the small field penumbra in order to analyze the potential dose perturbation caused by overlapping field to avoid the dose calculation errors in linear accelerator-based radiosurgery. Materials and methods. A ball phantom was fabricat...
