   Why the “Average Patient” Can’t Exist in Medical Imaging | Dr. Ehsan Samei

   In this episode of Rethink Imaging, host Chris St. John sits down with medical physics legend Dr. Ehsan Samei to dissect why medical imaging often treats patients as population aggregates rather than individuals. Dr. Samei breaks down the hidden "degrees of freedom" in scan acquisitions, challenges the industry's reliance on rigid manufacturer default protocols, and outlines how physicists and radiologists can work together to deliver truly personalized, patient-centric care.

   What 5.2 Million CT Scans Taught Us About Patient Radiation Dose | Tom Griglock & Kalpana Kanal

   In this episode of Rethink Imaging, host Chris St. John sits down with Dr. Kalpana Kanal and Dr. Thomas Griglock to discuss the newly updated Diagnostic Reference Levels (DRLs) and Achievable Doses (ADs) published ten years after the benchmark 2014 study. Analyzing a massive dataset of 5.2 million CT exams from 2025, they break down the 22% reduction in national DRLs, explain why low dose isn't always good dose, and emphasize why clinical optimization and diagnostic image quality must take precedence over endless dose reduction.
