Abstract: A two step method of enhancing the cavitational effect produced by ultrasonic signals focused at a specific location in a medium includes a first step of using one or more transducers to apply the ultrasonic signals to create a waveform that causes formation of bubbles at the location, and a second step of modulating the amplitude of the ultrasonic signals at a frequency of several Hz to several tens of kilohertz immediately following or coincident with the formation of the bubbles.

Abstract: An ultrasound cardiac stimulation system comprising: a spatially selective ultrasound source comprising at least one ultrasound transducer located outside the circulatory system; and a controller; where the controller generates an electrical response in the heart by directing the ultrasound source to transmit a high enough power level of ultrasound to one or more locations in the heart.

Abstract: A system and method for remodeling prediction using ultrasound are provided. The method includes obtaining ultrasound information relating to a heart and determining a likelihood of myocardial remodeling of the heart based on the ultrasound information.

Abstract: The present invention is a two step method of enhancing the cavitational effect produced by ultrasound signals focused at a specific location in a medium. The first step is to use one or more transducers to apply the ultrasound signals to create a waveform that causes formation of bubbles at the location and the second step is to modulate the amplitude of the ultrasound signals at a frequency of several Hz to several tens of kilohertz immediately following or coincident with the formation of the bubbles. The method of the invention can be effectively used for therapeutic purposes.

Abstract: Methods and associated apparatuses for imaging a target. An echo sequence image of the target is acquired and a log spectrum of at least a portion of the echo sequence image is computed. A point spread function is estimated by one of two methods. According to the first method, a low-resolution wavelet projection of the echo sequence log spectrum is used as an estimate of the log spectrum of the point spread function. According to the second method, an outlier-resistant wavelet transform of the echo sequence log spectrum is effected, followed by soft-thresholding and an inverse wavelet transform. Under both methods, a frequency domain phase of the point spread function also is estimated, the relevant portion of the echo sequence image is deconvolved using the estimated point spread function.

Abstract: A modular assisted visualization system includes an image manipulation module in communication with a work piece manipulation device, a camera module and at least one remote image manipulation module. The camera module, which is coupled to the work piece manipulation device and includes a camera lens and a light, provides a visual image of a work area of the work piece manipulation device. The visual image provided is displayed on the image manipulation module. The image manipulation module lays down at least one of a grid and a cut line on a work piece, by using the camera lens. The grid or cut line is established by data received by the image manipulation module from an operator. The work piece manipulation device, controlled by the image manipulation module, is engaged upon the grid or cut line established on the work piece.

Abstract: A method and an associated apparatus for imaging a target. An echo sequence image of the target is acquired and a log spectrum of at least a portion of the echo sequence image is computed. A low-resolution, shift-invariant wavelet projection of the echo sequence log spectrum is used as an estimate of the log spectrum of the point spread function. A frequency domain phase of the point spread function also is estimated. The relevant portion of the echo sequence image is deconvolved using the estimated point spread function.

Abstract: A method and apparatus for analyzing the electrical activity of the heart by Body Surface Potential Mapping (BSMP) in which an array of electrodes are applied over the thoracic region of a subject's body for producing measurements of the electrical signals generated in the thoracic region, and the measurements are processed for indicating certain electrical events in the subject's body. The array of electrodes are utilized to measure only the times of crossing of the electrical signals over a preset threshold.
