session DESCRIPTION
Photon-counting CT (PCCT) has recently become commercially available in diagnostic radiology and represents a major advance in x-ray imaging technology. By providing energy-resolved, quantitative imaging data with improved spatial resolution and noise performance, PCCT holds significant potential for radiation oncology. Emerging applications include improved target and organ-at-risk delineation, more accurate material composition and electron or stopping-power estimation for dose calculation, particularly relevant for particle therapy, as well as enhanced outcome analysis for biologically or functionally informed adaptive radiotherapy strategies. As PCCT is a new and rapidly evolving technology, its introduction into radiotherapy requires a careful and informed assessment of both its opportunities and challenges. Understanding how PCCT data can be translated into clinically actionable information, how it integrates into existing simulation and planning workflows, and what technical, clinical and operational adaptations are needed will be essential for successful adoption. Equally important is establishing a shared language to communicate the value and limitations of PCCT across physicians, physicists and other stakeholders. This education symposium will bring together experts in medical physics, imaging science and clinical radiation oncology to review the fundamental principles of PCCT, discuss emerging radiotherapy applications and examine practical considerations for implementation. Through interdisciplinary perspectives, the session aims to stimulate discussion, clarify clinical decision making pathways informed by PCCT data, and foster collaboration to guide the thoughtful integration of this technology into future radiotherapy practice.
