Abstract

Various embodiments of molds and methods are disclosed herein for fabricating a radio frequency (RF) coil. The disclosed mold includes a cylindrical inner core having a first helically shaped groove formed within an outer surface of the cylindrical inner core, and a two-piece compression sleeve having a second helically shaped groove formed within an inner surface of the two-piece compression sleeve. When portions of the two-piece compression sleeve are attached together, the two-piece compression sleeve surrounds the cylindrical inner core and provide a compressive force to a conductor arranged within the first and second helically shaped grooves to fabricate the RF coil. In some embodiments, a three-dimensional (3D) printing process may be used to fabricate each piece of the mold separately.
