Real-time MRI has the potential to enable many intraoperative surgical processes, but there is a great need within the MR community for extensible software platforms that can allow rapid development of tools for MR guided procedures. One such platform is based upon the RTHawk system for real-time acquisition and reconstruction and the Vurtigo system for interactive visualization. We use this platform to develop a system for performing targeted intracerebral infusions under MRI guidance. Initial testing of our system in phantoms and ex vivo brains has shown targeting accuracy on the order of 1-2 mm.
