- In this episode of Rethink Imaging, host Chris St. John sits down with Dr. Nina Kottler, Associate Chief Medical Officer of Clinical AI at Radiology Partners. Moving past basic lesion detection, Dr. Kottler addresses the massive 10x capacity-volume mismatch causing severe turnaround delays across healthcare systems. She breaks down the shift from fragmented, narrow AI tools to agentic foundation models and explains why funding clinical AI governance is key to sustainable medical innovation.
Where MRI Safety Standards Still Fall Short, and How to Fix Them with Tobias Gilk
13/08/2026 | 34 mins.In this episode of Rethink Imaging, host Chris St. John sits down with Tobias Gilk, an internationally recognized MRI safety expert and founder of The Invisible Force podcast. Moving beyond standard compliance checklists, Tobias exposes the critical gaps in modern MRI safety training, regulatory oversight, and physical environment workflows. From analyzing the fatal 2025 Long Island projectile accident to revealing how safety inefficiencies secretly drain facility revenue, this conversation provides a definitive blueprint for protecting patients while maximizing operational throughput.- In this episode of Rethink Imaging, host Chris St. John sits down with Tobias Gilk, a world renowned healthcare architect and certified MRI safety expert. Moving beyond the standard industry assumption that MRI is entirely risk free due to its lack of ionizing radiation, Gilk pulls back the curtain on the critical, unique physical hazards lurking inside the magnet room. From analyzing tragic projectile accidents to tracing why modern imaging workflows are fundamentally broken, this conversation explores how true safety in radiology requires rethinking the architecture of patient screening from the ground up.
Medical Imaging Professionals Need More Than Recognition: They Need Influence with Brandon Smith
23/07/2026 | 47 mins.In this episode of Rethink Imaging, host Chris St. John sits down with Brandon Smith, the historic first-ever back-to-back sitting president of the American Society of Radiologic Technologists (ASRT). Moving past the typical industry discussions around staff shortages, Brandon challenges the medical imaging community to reject quiet martyrdom, step out from behind the "ancillary" shadow, and transition from mere volunteerism to aggressive professional advocacy.Why Most Radiology AI Fails: Workflow, Governance & Integration Problem with Tessa Cook
09/07/2026 | 42 mins.In this episode of Frame by Frame: Rethink Imaging, host Chris St. John sits down with Dr. Tessa Cook, Vice Chair of Practice Transformation and Director of the Imaging Informatics Fellowship at Penn Medicine.
