Medical Physics 3.0: Redesigning Image Quality for Diagnosis | Dr. Ehsan Samei

Medical Physics 3.0: Redesigning Image Quality for Diagnosis | Dr. Ehsan SameiMedical Physics 3.0: Redesigning Image Quality for Diagnosis | Dr. Ehsan SameiMedical Physics 3.0: Redesigning Image Quality for Diagnosis | Dr. Ehsan Samei DrFor decades, medical physics has focused heavily on machine performance, equipment maintenance, and regulatory compliance. But as imaging technology matures, is ensuring machine compliance enough to guarantee optimal patient outcomes? In this episode of Rethink Imaging, host Chris St. John is joined by Dr. Ehsan Samei to detail the transition to Medical Physics 3.0, a framework that shifts the focus from "physics for machines" to "physics for and with patients." Dr. Samei explains how to translate scanner parameters into task-generic image attributes like noise and resolution and ultimately into task-specific clinical requirements, ensuring image quality matches the diagnostic question. The conversation dives deep into practical protocol management, combating the artificial divide between clinical and research physics, and addressing the concept of "good enough" image quality in an era of dose obsession. Finally, Dr. Samei outlines how radiologists and physicists can partner as equals to order task-driven imaging and deliver truly personalized care. What You'll Learn: The Medical Physics 3.0 Framework: Shifting focus from machine compliance to patient-centric, task-driven clinical physics (3.0). Translating Across Three Image Quality Zones: How physicists map scanner settings to generic attributes (noise/resolution) and then to task-specific clinical needs. Bridging Clinical & Research Physics: Why the divide between research and clinical physics is artificial and how clinicians must apply the latest findings. Navigating "Good Enough" & Radiation Obsession: Balancing frugality in radiation dose and scan time with the necessity of diagnostic confidence. Optimizing Protocol Workflows: Actionable steps for physicists to audit large protocol buckets and create indication-specific scanning protocols. The Triad Partnership: How radiologists, technologists, and physicists can collaborate as equal partners to say "make it so" for every exam.

But as imaging technology matures, is ensuring machine compliance enough to guarantee optimal patient outcomes?

In this episode of Rethink Imaging, host Chris St. John is joined by Dr. Ehsan Samei to detail the transition to Medical Physics 3.0, a framework that shifts the focus from "physics for machines" to "physics for and with patients." Dr. Samei explains how to translate scanner parameters into task-generic image attributes like noise and resolution and ultimately into task-specific clinical requirements, ensuring image quality matches the diagnostic question.

The conversation dives deep into practical protocol management, combating the artificial divide between clinical and research physics, and addressing the concept of "good enough" image quality in an era of dose obsession. Finally, Dr. Samei outlines how radiologists and physicists can partner as equals to order task-driven imaging and deliver truly personalized care.
