摘要

In conventional surface coils it was always necessary to compromise between large surface coils having a high measuring field and high penetration depth but low resolution, and small surface coils having a small measuring field and low penetration depth but high resolution. The object of the invention is to design a surface coil in such a way that it can be used universally. …??The surface coil (19) according to the invention consists of a plurality of conductor sections (19b - 19h) which can be connected via switches (20 - 23) to one another and to the tuning unit (19a) so that, depending on the setting of the switches (20 - 23), the conductor sections connected to the tuning unit enclose different areas. The effective area of the surface coil (19) can consequently be matched to the particular requirements by suitably setting the switches (20 - 23). …??Surface coils for nuclear spin tomographs. …IMAGE…
