MRI, Magnets, Memories and Easter

Early 1980's. Great memories from when my wife and I were on the GE Healthcare team that developed the first 1.5T commercial MRI, Signa.


There were things we got wrong and there were spectacular successes. People, test labs, physics, physiology. Many of us experienced the very same events - but we didn’t all sit together every minute of every day. Our team mates have likely catalogued their memories in different perspectives and POV's.


But there is one thing that all of us would agree on - a singular, amazing truth: A never-before-seen magnet, cooled to almost absolute zero, ramping up to 1.5 Tesla field strength. Powerful enough to rip air tanks off the floor and fly them through the air. Composite RF coils in a long bore. A 50 centimeter diametric spherical volume of magnetic homogeneity for the imaging sweet spot. Human images reconstructed by computer algorithms, visible on a computer monitor. Truth. Those elements need be present in every person’s recollection who was legitimately close to the action. That is the central tenet of why 100’s of people gathered together in that place at that time. 


A  handful of researchers in Schenectady were the first to know. More of us assembled - including Angela and me - at a rambling Wisconsin industrial park for the early team. Then on to a cavernous new temple-like building in a nearby city. But the MRI itself?  Powerful, brilliant, imposing, transformational, sensational, revolutionary...unforgettable.  And it marks a fixed narrative in time: Magnet, absolute zero cooling, proprietary RF coils, patient-subject, computer reconstruction, images on a screen. 



Folks still living can rightly correct me or add depth. I was there, they were there. We were together for about three years at the height of the blockbuster Signa introduction.  What a hearty, hard working group of individuals!


That, I believe is a glimpse into what may have occurred in the years following Jesus' ministry. Marked by the earth shaking weekend of death and resurrection we now call Easter. Gospels and letters were assembled within decades following those indelible, miraculous events.



That's all I meant to say. The detailed accounts of Jesus were contributed by people legitimately close to the action - about as many years in their past as the Signa MRI is to me and my bride. Looking back forty years on what was for us an epic historic event - albeit one that pales in comparison - yes, I do believe the New Testament chroniclers got it right.  

What do you believe?

He is my Lord and Savior. I get to share how died and rose again the world.

Interesting perspective. I wonder if you had kept on working in that field and used the technology daily how your memories would have been sharpened. I have to go back to things like moving to Cincinnati and starting my new job, marrying and having children to recall things that long ago. Thanks for the reminder of what occurred with the new Church.

And so much of what you all experienced that day was happening "sight unseen. " You knew God's laws of nature and scientific genius were behind it all, gifting people with new knowledge and another tool to heal His children. And yet, it took time for some medical personnel and scientists to believe and trust the validity (the truth) of what was presented to them.
