摘要： Methods and associated apparatuses for imaging a target. An echo sequence image of the target is acquired (10) and a log spectrum of at least a portion of the echo sequence image is computed. A point spread function is estimated (14) by one of two methods. According to the first method, a low-resolution wavelet projection of the echo sequence log spectrum (22) 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 (44), followed by soft-thresholding (46) and an inverse wavelet transform (48). 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.

摘要： The current invention provides a method for improving the sesitivity of bolometric detection by providing improved electromagnetic power/energy absorption. In addition to its role in significantly improving the performance of conventional conducting-film bolometric detection elements, the method suggests application of plasmon resonance absorption for efficient thermal detection and imaging of far-field radiation using the Surface Plasmon Resonance (SPR) and the herein introduced Cavity Plasmone Resonance (CPR) phenomena. The latter offers detection characteristics, including good frequency sensitivity, intrinsic spatial (angular) selectivity without focusing lenses, wide tunability over both infrared and visible light domains, high responsivity and miniaturization capabiliies. As compared to SPR, the CPR- type devices offer an incresed flexibility over wide ranges of wavelengths, bandwidths, and device dimensions. Both CPR and SPR occur in metallic films, which are characterized by high thermal diffusivity essential for fast bolometric response.

摘要： A device for determining the internal structure of a bone along a path directed into the bone (or other tissue) is disclosed. The device comprises a nozzle fluidically connected to a liquid reservoir for providing a liquid jet directed at the bone in the direction of the path; an ultrasonic transducer for generating ultrasonic waves through the liquid jet and for detecting echoes of the ultrasonic waves caused by changes in the acoustical impedance in the bone characterizing changes in the structure of the bone along the path; and an analyzer for interpreting the echoes into meaningful information relating to the location of the structural changes along the path.

摘要： 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.

摘要： The invention is a method of using ultrasound waves that are focused at a specific location in a medium to cause localized production of bubbles at that location and to control the production, and the cavitational and heating effects that take place there. According to the method of the invention, the production and control is accomplished by selecting the range of parameters of multiple transducers that are focused at the location such that they produce by interference specific waveforms at the focal point, which are not produced at other locations. Preferably the region within the focal zone of all the transducers in which the specific waveform develops at significant intensities, is typically very small. The invention is also a system for carrying out the method. The method and system of the invention can be used to perform a variety of therapeutic procedures. Typical of such procedures is occlusion of varicose veins.
