Abstract: The Energy Field and Target Correlation System automatically correlates the characteristics of target particles and a living organism to compute the characteristics of an energy field that is applied to a living organism to activate the target particles which are bound to or consumed or taken up by invasive agents in the living organism to produce detectable effects which can be used to image and treat the invasive agents. The energy field must be crafted to properly control the response and localize the extent of the illumination. The System automatically selects a set of energy field characteristics, including: field type, frequency, field strength, duration, field modulation, repetition frequency, beam size, and focal point. The determined energy field characteristics then are used to activate field generators to generate the desired energy field.
