METHODS ASSOCIATED WITH MRI SURGICAL SYSTEMS FOR REAL-TIME VISUALIZATIONS USING MRI IMAGE DATA AND PREDEFINED DATA OF SURGICAL TOOLS
First Claim
1. A method for carrying out an MRI-guided surgical procedure, comprising;
- obtaining MRI image data of a patient;
electronically segmenting the MRI image data to identify known fiducial markers on at least one surgical tool using electronically recognizable predefined physical characteristics of the at least one surgical tool;
electronically calculating user adjustments to move at least one of a pitch, roll and/or X-Y actuator to adjust a trajectory of a trajectory guide; and
displaying the calculated user adjustments to at least one display associated with an MRI suite thereby facilitating an MRI-guided surgical procedure.

Abstract
MRI-Surgical systems include: (a) at least one MRI-compatible surgical tool; (b) a circuit adapted to communicate with an MRI scanner; and (c) at least one display in communication with the circuit. The circuit electronically recognizes predefined physical characteristics of the at least one tool to automatically segment MR image data provided by the MRI scanner whereby the at least one tool constitutes a point of interface with the system. The circuit is configured to provide a User Interface that defines workflow progression for an MRI-guided surgical procedure and allows a user to select steps in the workflow, and wherein the circuit is configured to generate multi-dimensional visualizations using the predefined data of the at least one tool and data from MRI images of the patient in substantially real time during the surgical procedure.

10. A method of operating an MRI-guided surgical system, comprising:
-
electronically recognizing predefined physical characteristics of at least one surgical tool to automatically segment MR image data provided by an MRI scanner during an MRI-guided surgery whereby the at least one tool constitutes a point of interface with the system; and displaying a User Interface on a display that defines workflow progression for an MRI-guided surgical procedure and allows a user to select steps in the workflow; and generating multi-dimensional visualizations using predefined data of the at least one tool and data from MRI images of the patient in substantially real time during the surgical procedure. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
