Here we propose a device that provides a physician with real time control of scan planes for interventional MRI applications. The device position and orientation is obtained by acquiring the position of three internal active tracking markers. Signal from the device is transmitted wirelessly, making it easy to manipulate inside the magnet bore. The device's spatial information is used to prescribe the scan plane for a real time sequence and is repeated before each repetition. Phantom studies show the tracking device system to be accurate, and the use of the system is presented with a human volunteer.
