In MR-guided interventional procedures it is important to be able to quickly and automatically re-position the imaging slices to contain the active device in order to safely guide the procedure. Manual repositioning of the slice is time-consuming and inaccurate. We present a method that computes a parameterization of the active device from sparse 2D projection images. The parameterization is used to calculate the slice position and improve visualization of the device. It can be used for a variety of active devices and the imaged slice(s) can be located at specific segments of the device.
