We present an MR-guidance prototype designed to provide neurosurgeons with an interface having similar viewpoints to those commonly used in stereotactic operating room settings. Flexible and interactive interface that leverages real-time MRI sequences. 
Three displays, all individually acquired. Images are acquired in real time using a real-time Spiral GRE sequence. Each display can show a different view plane in real time by applying interactive tools. For example, a sample catheter trajectory is shown in red. The top-left axial display was rotated. The top-right view shows a perpendicular, but collinear display. The bottom image is perpendicular to the trajectory and shows the probe’s eye view. Parameters also adjustable.
Three reference planes and a main display. Images are acquired in real time using a real-time Spiral GRE sequence. The main display can be changed to show a different view plane in real time by manipulating a graphic slice Rx on any of the three reference planes. For example, a sample plane holding the catheter trajectory is shown in red on the sagittal display in red. By selecting a perpendicular plane, shown in green, the probe’s eye view can be observed in real time. Parameters adjustable.
