We developed process for fabricating patient-specific MRI receive coils via scalable and adaptable additive manufacturing approaches. Process relies on spray-depositing solution-processed electronic materials onto 3D printed custom substrates. We conducted careful materials selection, process optimization and fabricated fully functional coils. The coils spray deposited onto spherical substrate demonstrated higher SNR than control coil, when evaluated using phantom of the spherical shape, due to superior conformability to the phantom. Our approach is poised to enhance high quality clinical imaging by ensuring optimum fit of the MRI receive coils to the body parts with complex geometries, enabling reproducible placing on the patient and eliminating motion artifacts.
