"The lower-power machine was much cheaper to manufacture and operate, more comfortable and less noisy for patients, and the final images after computational processing were as clear and detailed as those obtained by the high-power devices currently used in the clinical setting."

Easier to scale up than down once you have a starting point like this.

“Tesla” is a unit of measure for magnetic strength; and not the car manufacturer.

I figured they were using 1/20th of Nikola Tesla's cadaver. That's the only logical interpretation of that headline.

lmao, same bro. I reading the paper and only then I discovered it’s about the viability of a low powered MRI machine for diagnostic imaging.

Particularly useful in poorer countries.

Medical imaging devices and medical devices in general are a racket. There are only a few companies and they are legal and lobbying departments first and foremost. This isn't the first time radical and radically cheaper prototypes have been proposed, but the unsolved bit it actually convincing anyone to buy.

A colleague had a device and a veteran adviced him to 10x the price.

8mm slice thickness isn't particularly at odds with what is commonly done on commercial machines, though usually there is a second transverse scan (which can't be readily fused due to patient movement).

But even if it were, plenty of interesting structures are many centimeters in size, a thousand fold decrease in costs from eliminating cryogenic / high power magnets could be very useful.

300-1800W power draw seems impressive! It looks like standard machines are using something on the order of 25kW while scanning, which certainly sounds prohibitive for less developed infrastructure.
