Exhibition of a Tesla Coil

Solid State Tesla Coil

Some years ago I developed an interest in Tesla coils. I was teaching a senior elective course at Kansas State University where we talked about power MOSFETs and topics related to high voltages and currents. I decided to use a Tesla coil as a class project. We would talk about design aspects, then design, build, and test a coil. The best description of the results of that plan was fiasco, or ma...

Reengineered Helmet Coil for Human Brain Studies at 3 Tesla

We describe the further development of a circularly polarized helmet coil for magnetic resonance imaging (MRI) of the human brain at 3 T. The coil is used in transmit and receive (transceive) mode, a useful alternative over commercially available quadrature headcoils with scanners where phased arrays are unavailable. The coil is simple to build. Its structure is based on an assembly of two copl...

A 13 channel 3 Tesla Shoulder Coil on a Domed Conformable Former

Introduction: MRI provides an essential tool for musculoskeletal radiology. The highest quality images are obtained with anatomically specific RF coil designs, customized to the anatomy of interest. The shoulder presents a difficult target, however, because of wide variations in body habitus and the difficulty of arranging coil elements around the shoulder to optimize sensitivity. The most comm...
