Mary Lou Jepson discussed her work to make wearable MRI at ApplySci’s Wearable Tech + Digital Health + Neurotech conference at the MIT Media Lab on September 19, 2017.
LCD pixels are getting down to the wavelength of light.
The human body is translucent to near infrared light.
They use holography to record all of the light that is scattered, they shine a light on the scattered light to invert the light.
This is antiholography.
They can then adjust the resolution down to the micron.
LCD and camera chips and software can replace a multimillion dollar MRI machine that will work faster.
Nextbigfuture notes that wearable MRI will let first responders know what kind of stroke someone is having (clot or bleedout). You can then give the right drug to save their life in the diamond half hour.
It could be used to monitor and bring MRI everywhere.
They are making them into ski hats or shirts.
