hasn’t the efficacy of this been called into question?
apparently, as a test, they scanned a business czar’s chest. it showed nothing.
then they scanned a politician’s head. again, nothing.
Sounds like it works fine then
I hate to burst everyone’s bubble, but this is just MRI with a new and different kind of tracer.
There will likely be some great clinical applications from this, but it’s not a game changer. It needs a big, expensive, superconducting magnet.
It’s also not radiation free (just like MR). It’s just ionizing radiation free.
"Our iMPI scanner is so small and light that you can take it almost anywhere,” Vogel explains.
Obviously when they say “radiation free” they mean “ionizing radiation free”. The term “electromagnetic radiation” includes things like radio waves and visible light, not just high energy ionizing stuff like UV, x-rays, and gamma rays. Literally everything emits some amount of non-ionizimg radiation. Non ionizing EM is pretty harmless unless you have enough of it to cause heating/burns.
I wasn’t speaking to people like you when I explained radiation. I was speaking to everyone who can’t distinguish this from magic. You’ll also have to understand that tissue heating is a concern in some instances, as is “running around in a large magnetic gradient”. (Guess what happens?)
Vogel has something to sell. The whole article explicitly uses words that the lay public will misunderstand to attract attention in the popular press. This whole article is a puff piece. It’s based on real science, but it is not intended to give the reader an accurate picture of what he’s selling.
There are small MRs that you can move on the back of a semi or keep in a room adjacent to an OR. That’s what he’s saying when you translate this statement into something that remotely resembles the truth.
Very exciting.

Just wish I hadn’t opened that site in Safari on iPhone first, putting it in reader mode crashed it so hard I had to restart my phone.
> Such nanoparticles do not occur naturally in the human body and must be administered as markers
So if I’m reading this right, much like radioactive markers, these must be surgically implanted before they can capture the imaging? In other words, it’s not a direct replacement for MRI or X-ray imaging technologies, though it could potentially be safer for long term care patients that need frequent imaging.
I wish the article touched on the nano particles more… like, what happens to them after you’re done? Are they dissolved or expelled (or do they pile up in various parts of the body and cause chronic issues…)?
I don’t get the hype. I can do this right now, just get me a knife.
What’s new? We’ve had such technology for decades, and at a very cheap price too! /s
Terahertz imaging devices when?
