Efficient closed loop feedback navigation

The present invention provides a means for guiding a medical device within the body to approach a target destination. The system and method provide a means for determining a predicted length and orientation, navigating the device to an intermediate point less than the predicted length, determining an error between the projected destination and actual target destination, and successively updating a predicted value of a control variable to yield an orientation within a predetermined distance error before advancing the device the remaining distance to the destination. This provides a physician with the capability of verifying the device will be accurately guided to the target destination without trial and error. A method is also provided for intuitive navigation to targets with limited trial and error based on user-applied device orientation adjustments, where the user chooses the magnitude of the adjustments and the system determines the adjustment direction.

Methods for Implementing Microbeam Radiation Therapy

A method of performing microbeam radiation therapy (MRT) includes delivering a dose only to selected tissue in a target volume (10) with continuous broad beam, first, by interleaving arrays of microplanar beams (30,36) only at the target (10). Administered contrast agents can supplement the effect by preferentially increasing the target dose relative to dose in normal tissue. A broad beam effect is alternatively created using non-interleaving microbeam array(s) with scattering agents administered to selected tissue that preferentially increase valley dose (69) within target to approximate broad beam. The methods of interleaving microbeams are also applied to treat diseases and conditions by ablating at least a portion of selected tissue, or by damaging blood-brain barrier for efficient drug and / or cell administration. A system for performing interlaced microbeam radiosurgery preferably includes two orthogonal radiation source arms (102) for producing and interleaving microbeam arrays (30,36) at the target volume (10). The methods treat tumors, pain, epilepsy, and neurological diseases.
