Presented by Justin Roper, PhD and Kirk Luca, MS, CMD
Emory University
This presentation reviews key lung SBRT clinical trials and the planning literature that define modern plan quality goals, while highlighting how our own research has helped redefine what is achievable in clinical practice. Using multiple real-world examples, we will show how beam geometry drives dose conformity and dose fall-off, and discuss practical VMAT optimization strategies that improve plan quality while maintaining safe, reliable deliverability.

Presenters:
Justin Roper, PhD, DABR, is an Associate Professor of Radiation Oncology and Clinical Lead Physicist at Emory University. He is passionate about treatment planning and the development of practical, innovative strategies to improve plan quality. Dr. Roper led the physics initiative to establish a medical dosimetry graduate program at Emory in partnership with Southern Illinois University. Over the past decade, graduates of the program have achieved a 100% pass rate on the MDCB examination, and student research projects have been published in peer-reviewed journals, including Editor’s Choice selections in Medical Dosimetry, as well as earning first- and second-place awards in the AAMD Student Writing Competition. A major focus of this research has been the development of techniques for creating high quality, safely deliverable lung SBRT treatment plans using strategic beam geometries and minimal optimization objectives.
Kirk Luca, MS, CMD, is the Dosimetry Program Development Manager at Emory Healthcare, where he leads the development, standardization, and clinical adoption of advanced treatment planning workflows. He oversees key initiatives including Emory’s RapidPlan development group, automated planning efforts, and workflow implementation designed to improve consistency, safety, and efficiency. Kirk partners closely with dosimetrists, physicists, and physicians to translate planning innovation into reliable, clinic-ready solutions, while also mentoring dosimetry trainees and leading student research projects. He has presented at AAMD on treatment planning and the clinical impact of strategic beam geometry, with a focus on simple, teachable strategies that elevate plan quality. He also serves as an Associate Editor for Medical Dosimetry, supporting the dissemination of high-quality research that advances the field.
