As part of a multi-center effort to design and build an accessible 1.5 T head-only MRI scanner (NIH U01EB025153, PI M. Garwood), we designed and constructed a prototype multi-coil array fitting the limited available space and capable of generating linear and non-linear image encoding fields as well as strong concomitant localized B0 shim fields. Here, we describe the construction process, and present system characteristics as well as experimental validation of its field generation capabilities utilizing a conventional 4 T MRI scanner.
