ABSTRACT:
A flexible catheter or other object for insertion into an object is designed for use in connection with magnetic resonance (MR) imaging techniques. The catheter carries a closed loop coil arrangement tuned to the RF excitation frequency used in operation of an MR imager. The coil arrangement includes turns which lie substantially in non-parallel planes when the axis of the catheter is in a straight line. The coil arrangement may include two coils which are constituted by different sections of an electrically conductive track carried on a flexible, insulating substrate. According to another embodiment, the coil arrangement may comprise two separate closed loop tuned coils each constituted by a narrow metallized track carried on a flexible, insulating substrate. In another embodiment, the coil comprises turns of a saddle form.
