| 20090264798 | SYSTEM AND METHOD FOR CONTROLLING ENERGY DELIVERY USING LOCAL HARMONIC MOTION - 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. | 10-22-2009 |
| 20100125192 | FOCUSED ULTRASOUND SYSTEM - A focused ultrasound system includes an ultrasound transducer configured to emit focused ultrasound energy toward a subject and a positioning system configured to position the ultrasound transducer to localize the focused ultrasound energy within a target location. The positioning system includes a drive apparatus to translate the ultrasound transducer along at least one axis of motion and a motor controller to control the drive apparatus. The focused ultrasound system also includes a control system connected to the motor controller that is programmed to receive imaging/location data from an imaging system, determine positional coordinates of the target location based on the imaging/location data, and register the positional coordinates of the target location with the positioning system. The positional coordinates are sent to the motor controller via an input signal to cause the motor controller to control the drive apparatus so as to translate the ultrasound transducer. | 05-20-2010 |

| 20110319793 | THERMAL THERAPY APPARATUS AND METHOD USING FOCUSED ULTRASONIC SOUND FIELDS - Apparatus and method for delivering increased amounts of energy to localized treatment zones in a target tissue volume are provided. In some instances the non-linear wave propagation and other properties of the treatment apparatus and propagation medium as well as novel beam forming and control of the treatment apparatus are employed to generate extended focal zones for efficient treatment of a condition in a patient. | 12-29-2011 |
