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