A system and method for control of energy application to a target location based on a measured localized harmonic motion is disclosed. The system includes a first energy source configured to deliver a beam of energy to a subject to induce mechanical vibration of a desired region, a second energy source configured to deliver a second beam of energy into the desired region, and a receiver configured to receive echo signals from the desired region indicative of reflected energy from the second energy source. The system also includes a computer programmed to analyze at least one of amplitude, phase, and frequency of the vibration of the desired region indicated by the received echo signals, monitor the amplitude, phase, and/or frequency of the vibration in the desired region during application of the beam of energy, detect a change in the amplitude, phase, and/or frequency of the vibration in the desired region and, if the change exceeds a pre-determined size and rate, generate an alert. |
