Circularly polarised local antenna arrangement for nuclear spin tomography appts. - has array of three or more linearly polarised coils overlapped to achieve geometric decoupling.

摘要

The antenna arrangement consists of an array of at least three linearly polarised local coils (20-23) which overlap each other to the extent that they are geometrically decoupled. Each local coil is separately connected to a combination network (36). The network performs a complex combination of the output signals of the three local coils resulting in high frequency output signals (b5,b6) which represent circular polarisations. USE/ADVANTAGE - For nuclear spin tomography device. Antenna arrangement is designed for problem-free decoupling between individual elements.
