ABSTRACT:
One or more flexible magnetic Resonance (MR) receive coils are constructed of a flexible material and connected to a flexible base to produce a module. Each module has the coils overlapping by a predetermined amount to minimize coupling between the coils. The modules may be connected by attachment means placed at predefined locations to cause overlap of adjacent coils such that the coupling is minimized. Balanced-unbalanced ("baluns") may be used to couple each receive coil to its lead cable connecting it to the MR imaging electronics. The baluns effectively isolate the coils from the cables and each other to optimize signal-to-noise ratio of the received signal.
