1. A method for deploying a needle structure in tissue, said method comprising:
- positioning a probe having a deployable needle structure near an anatomical feature in the tissue;
providing a real time image of the tissue including the anatomical feature to be treated on a display connected to a controller;
projecting a treatment region and a safety region on the real time image prior to deploying the needle structure;
adjusting a size and a position of a boundary of at least one of the projected image of the treatment region and safety region on the real time image prior to deploying the needle structure, wherein adjusting the size and position of the projected boundary comprises adjusting a user interface connected to the controller; and
deploying the needle structure from the probe, wherein the needle structure is positioned relative to the probe and the tissue to provide treatment within the projected boundary after the projected boundary has been adjusted.

Abstract
A system for deploying needles in tissue includes a controller and a visual display. A treatment probe has both a needle and tines deployable from the needle which may be advanced into the tissue. The treatment probe also has adjustable stops which control the deployed positions of both the needle and the tines. The adjustable stops are coupled to the controller so that the virtual treatment and safety boundaries resulting from the treatment can be presented on the visual display prior to actual deployment of the system.
