Circuit board i.e. rigid or flexible printed circuit board, for use in spinal column coil for magnetic resonance applications, has base shielding arranged on upper side and/or under side, and additive shielding connected with base shielding

摘要

The board has a strip conductor connected with a respective local coil for magnetic resonance applications or with a contact arranged on an upper side (1) or an under side (2) of a terminal (8') for a protected cable. The local coil and/or the terminal are arranged in proximity of a front end (6) of the board. A base shielding e.g. wide metal film, is arranged on the upper side and/or the under side for frequencies in a magnetic resonance region. An additive shielding is electrically connected with the base shielding in the magnetic resonance region and on narrow sides (5).
