NMR imaging with special high frequency antennas

The contribution describes special HF coils and the relevant physical and anatomic criteria they fulfill for various applications (such as examination of the eye, inner ear, spine, chest, and bone joints). In order to quantify the gain in the signal-to-noise ratio achievable with these coils, comparative measurements with standard HF antennas have been made using phantoms, or volunteers. The spatial resolution thus achieved is shown by a number of illustrations. (orig./TRV)
