A sparse orthogonal collimator for small animal intensity‐modulated radiation therapy part I: Planning system development and commissioning

Purpose To achieve more translatable preclinical research results, small animal irradiation needs to more closely simulate human radiotherapy. Although the clinical gold standard is intensity‐modulated radiation therapy (IMRT), the direct translation of this method for small animals is impractical. In this study we describe the treatment planning system for a novel dose modulation device to address this challenge. Methods Using delineated target...
