1. A system for telemetrical control of an interventional device for minimally invasive surgical procedure, comprising:

  • a Magnetic Resonance Imaging (MRI) scanner sub-system operated to produce substantially in real-time MR images of an operative site comprising a target of interest;

    an interventional device disposed at said operative site within said MRI scanner sub-system;

    a tracking sub-system operatively coupled to said MRI scanner sub-system and operating concurrently therewith, wherein said tracking sub-system is configured to automatically and continually produce tracking information corresponding to a location of said interventional device within said operative site, said tracking information being produced based on gradient fields of said MRI scanner sub-system;

    a processor controlled navigation sub-system operatively coupled to said tracking sub-system, said MRI scanner sub-system, and said interventional device, wherein said navigation sub-system is configured to;

    (a) integrate said tracking information with said real-time MR images,(b) display said substantially real-time MR images of said operative site generated by said imaging MRI scanner sub-system, and(c) fluidly interface with a user to present, in a continuous fashion, said real-time MRI images and said tracking information, and to receive the user'"'"'s commands to telemetrically control said interventional device to reach said target of interest in an optimal manner for an intended interaction therewith based on at least said substantially in real-time MR images and said tracking information.
