Abstract: An elongate device (e.g. a catheter) for interventional MRI has one or more passive LC-circuits (wireless markers) attached to its distal tip portion for position tracking. The LC-circuits comprise an inductor winding (480) and a three-dimensional "trench" capacitor (420-440) and are integrated in a piece of silicon (410). Optical fibres may be included in the device for optical probing of tissue surrounding the distal tip portion.
