A system for facilitating manual alignment of a needle with a planned path of insertion includes first and second cameras supported in fixed spaced relation by a frame such that the optical axes of the cameras form between them an angle of more than 30 degrees, and preferably roughly 90 degrees. A processing system generates video displays for both cameras. A line in each of the video displays corresponding to an input planned path of insertion is determined, and a visual indication of that line is generated on the video displays.
