INVASIVE DEVICE FOR USE IN A MAGNETIC RESONANCE IMAGING APPARATUS

摘要

The invention relates to an invasive device which is intended to cooperate with a magnetic resonance imaging apparatus and is provided with an RF coil which is situated near a distal part of the invasive device and can be coupled to a control unit via an electric connection. The RF coil is used so as to visualize the position of a distal end of the invasive device, introduced into an object, in an image of the object. Current induced by an RF field to be generated by the magnetic resonance imaging apparatus develops heat in the electric connection, which may be annoying to a patient. In order to counteract the development of heat in the invasive device, the invasive device is provided with a hollow carrier having a distal end and a proximal end. The electric connection extends through said carrier which is provided with an electrically conductive shield with an additional resistance.
