Patent ID: 8258789

Claim:
An apparatus comprising: a first RF coil integrated into a first printed circuit board (PCB); a second RF coil integrated into the first PCB; and an adjustable tuning member positioned adjacently to the first PCB and inductively coupled to the first and second RF coils, the adjustable tuning member configured to minimize a mutual inductance formed between the first and second RF coils via modification of a coupling constant between the first and second RF coils, wherein the adjustable tuning member comprises an electrically conductive material integrated into a second PCB, and wherein the second PCB is adjustably affixed to the first PCB such that the second PCB can be rotated or translated with respect to the first PCB to position the adjustable tuning member adjacently to a region between the first and second RF coils so as to minimize the mutual inductance between the first and second RF coils.
