Design and Implementation of MRI RF Coil Based on 3D Printing

3D printing is the latest developed rapid prototyping technology. It has been applied in the field of industrial design, architecture, automotive, aerospace, medical industries, etc. In this paper, 3D printing technology was used to made magnetic resonance imaging RF coils. The results shown that RF coil designed using 3D printing technology has the following advantages: firstly, the printing material PLA has good insulation properties and low RF loss. The coil made with PLA has high Q value. Secondly, the printing material PLA has no impact on the signals of imaged sample. Thirdly, material has good mechanical properties and the coil can be produced through rational design to made variety of structures to meet the needs of research and clinical applications. Low production cost for coils, especially for some of the complex shape of the coil, has a special advantage.
