16. A method for operating a guidance system for dynamically guiding a surgical needle catheter for a patient,
said system comprising an electromagnetic catheter configured for insertion into the patient and for defining a desired location to be reached by the surgical needle catheter; an electromagnetic tracker configured to track a location and orientation of the surgical needle catheter and of a location of a tip of the electromagnetic catheter; and an electronic data processor;
said method comprising carrying out by said electronic data processor:
displaying a 2D concentric-ring target, wherein said target is on a plane intersecting the tip of the electromagnetic catheter and the plane being perpendicular to the orientation of the surgical needle catheter;
continuously displaying, orthogonal to the plane, a projection of a line onto said 2D concentric-ring target, the line being coincident with the surgical needle catheter, wherein the projection of the line is displayed at a distance from a center of the 2D concentric-ring target when the surgical needle catheter is not pointed towards the electromagnetic catheter, and wherein the projection of the line is displayed at the center of the 2D concentric-ring target when the surgical needle catheter is pointed towards the electromagnetic catheter; and
continuously displaying a plurality of concentric rings centered around the tip of the electromagnetic catheter.
