Learning to build low-field MRIs for remote northern communities

Area of Science:

• Biomedical Engineering
• Medical Imaging Technology
• Remote Healthcare Solutions

Background:

• Accessible neuroimaging is limited in remote communities, like the Canadian North.
• Establishing local MRI construction and maintenance is crucial for operational continuity and community development.
• Developing technical skills within communities is key to supporting advanced medical technologies.

Purpose of the Study:

• To assess the feasibility of building low-field MRI hardware using resources available in remote communities.
• To establish an educational framework for training students in MRI construction and maintenance.
• To demonstrate the adaptability of aircraft maintenance skills for MRI development.

Main Methods:

• A prototype wrist-sized, radio frequency (RF) encoding MRI was constructed by a diverse student team.
• Skills utilized included 3D printing, sheet metal work, and electrical harness building, transferable from Aircraft Maintenance Engineering (AME).
• The project integrated students from high school to post-doctoral levels, fostering a collaborative learning environment.

Main Results:

• The project successfully built the hardware for a low-field MRI prototype.
• Aircraft maintenance skills proved sufficient for constructing the MRI hardware.
• The developed techniques are applicable to various MRI designs, including those for space applications.

Conclusions:

• Low-field MRI development is feasible in remote settings using existing technical skills.
• Educational programs centered on MRI construction can empower local communities and create technical career pathways.
• This initiative supports autonomous, accessible neuroimaging and technological self-sufficiency in remote regions.
