Why image integrity is never a small thing
Every artifact, every misalignment, every shortcut taken in the service area can echo through a diagnosis. A note on getting it right the first time.
Read More →Through Fire exposes the hidden war within MRI engineering, where patient safety, federal regulations, and corporate ambition frequently clash. With raw honesty, Marshall R. Shannon lays bare how an industry meant to save lives can become dangerous when vital safeguards are sacrificed for the sake of profit.
Marshall R. Shannon is Director of Operations at Image Technology Consulting LLC in Lancaster, Texas — an independent third-party service provider supporting MRI and CT equipment from Philips, Siemens, Hitachi, and other major OEMs.
Over more than twenty-five years in the field, he has installed, ramped, shimmed, and restored MRI systems for clinics and hospitals across the United States and internationally — with deep technical experience in cryogenic systems, mobile MRI refurbishment, and emergency escalated field service.
Read More About Marshall →Far more than a technical memoir, Through Fire is the personal account of a veteran engineer who spent decades installing and repairing MRI systems around the world — a career that put him at the forefront of an escalating corporate agenda bent on reshaping the rules and silencing those who spoke out.
It is a story about the people who keep these machines running, what happens when corporate culture starts prioritizing secrecy over safety, and the hard, quiet work of doing it right when nobody is watching.
Buy The BookThree decades of magnetic resonance imaging — from cryogenic ramp work and warehouse floors to the family and friends who shaped the journey.
Early responses from engineers, healthcare professionals, and readers from beyond the industry.
A rare window into a world most patients never see. Shannon writes with the calm authority of someone who has spent his life keeping people safe.
Equal parts memoir, technical primer, and conscience. I have never read anything like it. Required reading for anyone who works in medical imaging.
You don’t need to be in the industry to be moved by this book. It is fundamentally a story about doing the right thing in a system designed to discourage it.
Reflections on engineering, patient safety, and the quiet decisions that shape lives.
Every artifact, every misalignment, every shortcut taken in the service area can echo through a diagnosis. A note on getting it right the first time.
