We present a new software system that creates colored MIPs in real-time using pre-acquired MRA and MRCP data, and that allows us to render and to display dynamically these 3D MIPs with different colors interactively in real-time, by alpha-blending them with real-time reconstructed multi-slice images. The colorization improves the visibility of the vascular structures and will help to identify the orientation and the location of devices in real-time during MRI guided procedures, such as TIPS, angioplasty, biopsy, stent placement, and electrophysiology applications. Our software has the potential of improving patient safety and procedure efficacy for MRI-guided interventional applications.
