Abstract

A positioning device for positioning or an open MRI magnetic probe including an open MRI magnet in a plurality of positions and for controllably moving the probe between these positions. The positions include at least one imaging position of the open probe which allows the performing of magnetic resonance imaging procedures and surgical procedures on a body part, either sequentially or simultaneously, without moving the probe from the imaging position. The plurality of positions may include one or more positions in which the probe is retracted away from the body part to Increase the accessibility of the body part and to allow for use of magnetic field sensitive devices to be positioned near the body part. The positioning device includes a movable framework attachable to the probe and a position control unit operatively connected to the movable framework for controlling the moving of the framework. The framework may be motorized but may also include manually movable parts. The device is capable of moving the probe from one position to another with one or more degrees of freedom. The device may be adapted for repeatedly and accurately positioning the probe selected positions. Magnetic resonance imaging systems including the positioning device are also disclosed.
