MRI4ALL Hackathon: Under a Week Build of Open-Source Gradient Coils for a Low-Field MRI

Motivation: High production costs limit the accessibility of MRI. To break this accessibility and cost barrier, we demonstrate that affordable gradients can be designed and built in less than two weeks using open-source software and conventional 3D printing. Goal(s): To develop X, Y, and Z gradients for an ultra low-field Halbach MRI. Approach: We used open-source software to design the gradients. The casing was 3D printed, and the coils were manually wound. The fields were measured using an open-source field-mapping probe. Results: We constructed gradients that generated magnetic fields with great correspondence to simulated fields. 2D images were acquired with a fast spin-echo sequence. Impact: Open-source software can be used to design, build, and test MRI gradient coils in a quick and affordable manner. This demonstrates that open-source software for design of MRI hardware can lead to more accessible MRI.

Abstract

Motivation: High production costs limit the accessibility of MRI. To break this accessibility and cost barrier, we demonstrate that affordable gradients can be designed and built in less than two weeks using open-source software and conventional 3D printing. Goal(s): To develop X, Y, and Z gradients for an ultra low-field Halbach MRI. Approach: We used open-source software to design the gradients. The casing was 3D printed, and the coils were manually wound. The fields were measured using an open-source field-mapping probe. Results: We constructed gradients that generated magnetic fields with great correspondence to simulated fields. 2D images were acquired with a fast spin-echo sequence. Impact: Open-source software can be used to design, build, and test MRI gradient coils in a quick and affordable manner. This demonstrates that open-source software for design of MRI hardware can lead to more accessible MRI.
