Claim Text:
1. A system to facilitate MRI-guided procedures, comprising: a circuit comprising at least one processor and/or at least one Application Specific Integrated Circuit (ASIC); an intrabody device comprising a tip with a deflectable distal end portion which has variable curvature, wherein the intrabody device further comprises a plurality of spaced apart tracking coils residing on the deflectable distal end portion; and a display in communication with the circuit, the display having a User Interface (UI), wherein the circuit is configured to provide at least one volumetric planning map of relevant patient anatomy to the display, wherein the UI is configured to allow a user to select at least one target site and at least one avoid zone on the at least one volumetric planning map, wherein the circuit is further configured to define proximity alert locations for an MRI-guided procedure associated with the user selected at least one target site and/or the user selected at least one avoid zone, track the intrabody device by calculating a tip location and orientation of the tracked intrabody device using known physical data regarding the tracking coils and a predictable deflectable behavior of the deflectable distal end portion, and generate at least one audible and/or visual alert during the MRI-guided procedure when the tracked intrabody device is identified as approaching or being in one of the defined proximity alert locations, wherein the predictable deflectable behavior is based on forces applied to the intrabody device; wherein the circuit is further configured to register the at least one volumetric planning map to MRI 3-D image space associated with the MRI-guided procedure, determine preset scan planes that cover the at least one selected target site and/or avoid zone based on the user selected at least one target site and/or the user selected at least one avoid zone, and wherein, during the MRI-guided procedure, the circuit is configured to determine a location of the tracked intrabody device and automatically select a relevant preset scan plane from one of the determined preset scan planes to obtain an MRI signal.
