A photonic based non-invasive surgery system that includes an imaging device such as an MRI device and at least two beam generators for generating beams of energy for delivery to a target in the person's body, where the beams of energy intersect at a point. The system also includes a feed-forward control for precalculating anticipated deflections and resulting pathways as the beams of energy travel throughout the person's body, and a feedback control to obtain and use information gathered by the imaging device.
