Title: METHODS AND SYSTEMS FOR REAL-TIME PLANNING AND MONITORING OF ABLATION NEEDLE DEPLOYMENT IN TISSUE
Abstract:
A control handle of a treatment probe is manipulated to advance and/or deploy one or more treatment structures into tissue. The treatment probe is coupled to a display to show an image field including target tissue for treatment. Virtual treatment and safety boundaries are overlaid over the image field. The boundaries include virtual stop positions for the needle and tines. A joystick or directional pad on the probe handle, operable independently from the user interface to advance and/or deploy the one or more treatment structures, can be manipulated to adjust the size and/or position of these boundaries. Sensors within the probe detect the real-time position of the one or more treatment structures, and the sensed positions are displayed in real-time. The user can observe the display to deploy the one or more treatment structures to the displayed virtual stop positions.
