I am working on a project in which i want to replace the conventional MRI machines to a low-cost , low-power MRI machine using low power electro-magnets and non-linear image processing.If any of you guys have expertise in this domain please comment on the feasibility and scope of project.

Hello,

Low power will be lower field strenght, wich will lead to lower resolution.
For imaging you will still need strong field gradients.
What size of magnet do you have in mind?
Is it full body or pre clinical, like they use for mice and rats?

Currently, we are doing it for brain only to detect brain tumors. If we are able to do it successfully then we are planning to extend it for full body. Magnetic field intensity range will be from 50 to 100 uT.

Hello,

The 3T system has no use of external liquid helium and nitrogen:

It uses a compressor for cooling the magnet:

Cooling & Power Requirements
  • Magnet compressor cooling: water-water heat exchanger
  • Gradient cooling: water-water heat exchanger
  • Electronics cooling: air flow through cabinets
  • Typical heat dissipation to air: ~ 4.2 kW
  • Typical heat dissipation to facility water: ~ 11.0 kW
