| 2 | Sound inspection method and device using time inversion | JP24536393 | 1993-09-30 | JPH06341978A | 1994-12-13 | FUINKU MATEISU |
| PURPOSE: To determine a geometric feature of the wave front by repeating time inversion and re-propagation of extracted signals in a time window, and detect target reflection by an ultrasonic echo graph image to trace a position. CONSTITUTION: A center transducer of a matrix 12 of ultrasonic transducers 1,...n distributed in concentric circles first irradiates a target 10 in a medium 18 by the excitation of a circuit 14. A circuit 16 extracts each echo signal from the medium 18 and stores a relative position to waveform. Input signals are inspected to select a time window T of duration including extracted total reflection energy, and only the signals included in the window T are stored (16). The extracted signals in the window T are time-inverted first and propagated to all transducers with amplification gain, and received echos appear in a signal form symmetric to the center maximum value outputted from each transducer. This time inversion and re-propagation are repeated, and after 2n+1 times of time inversion, a geometric line or face of the wave front approximate to the maximum value of the signals can be determined.

| PURPOSE: To converge precisely ultrasonic beam to such a target as a calculus by utilizing technique referred to 'phase conjugate optical amplification' which is somewhat similar to 'phase conjugate mirror' to be used in optics. CONSTITUTION: An array 12 accompanying the first circuit 14 complements transducers 1, 2...n by way of the signals formulated and distributed to transmit the beam which is not converged in the direction of the target 10. The echo received by the transducer is converted to an electric signal. The size of a signal and time distribution location is stored by a circuit 16. The stored signal supplements the transducer of the receiver array 12 after the reversal of the time distribution and size of the signal. The feedback wave surface caused by the supplement is converged to the target 10 and the distortion which appears in the transmission route passing a medium 18 is precisely compensated by the feedback route. The divergent ultrasonic sound picked up by the array 12 generates constringing waves precisely converged. An amplification gain (g) between the electric signal transmitted by the transducer and the electric signal afforded by the circuit 16 gives a sound energy required for destroying the target 10.

| Image data relating to real-world objects or persons is collected from a scene while collecting audio data relating to the real-world objects or persons from the same scene. The audio data is used to derive sound objects corresponding to the real-world objects or persons. The image data is used to derive video objects corresponding to the real-world objects or persons. Based on the sound objects and the video objects, candidate salient objects are generated. A salient object is selected from among the candidate salient objects. Perceptual enhancement operations are performed on the selected salient object. | ||||||

| A system and method for reconstructing ultrasound images provides improvements in image quality by using and digitally processing the acquired data along a plurality of dimensions. The echo signal reflected off different features in the object is reconstructed into images by solving a regularized linear system of equations that involves the geometry of the imaging transducer and of the image field-of-view. Processing can be performed ahead of time to create reconstruction matrices that can be reused indefinitely for a given transducer and field-of-view. The present invention can include a temporal encoding and decoding scheme, which includes changes in the direction of propagation and/or focusing characteris-tics of the transmitted ultrasound field from one time frame to the next, to provide improved discrimination between desired object features and artifacts. | ||||||
| 13 | Method and apparatus for acoustic examination using time reversal | US125855 | 1993-09-24 | US5428999A | 1995-07-04 | Mathias Fink |
| A method for acoustic examination of a medium and detection of reflective targets includes a preliminary step of injecting a divergent sound beam into the medium from at least one transducer. Then the echo signals reflected by the medium and received by several transducers in an array are picked up. A time gate is used to select echoes coming from a particular zone of the medium. The echoes are stored, time-reversed and re-emitted. The signals newly reflected by the medium are stored and the time-reversal operation is repeated. After a final time reversal of rank 2n+1 (where n is a positive non-zero integer) over the full depth of the measurement time gate, the characteristics of the wavefront passing closest to the maxima of the signals are determined, advantageously in the form of a time distribution of the maxima. The characteristics can often be approximated with a polynomial law. An apparatus is disclosed for implementing the method. | ||||||

| A progressive beamformer in an imaging system includes a number of stages. A first stage delays and combines a number of received data streams to align the streams to a point of interest on a first beamline. The first stage feeds a number of subsequent stages that operate to buffer and re-delay at least a portion of the data streams received from a previous stage in order to align the data streams to a point of interest on a new beamline. In one embodiment, each stage operates to reduce the number of data streams that are passed to a subsequent stage without suffering from grating lobes. A beam reclamation process includes a number of stages that receive data streams from end elements in order to produce reclaimed beams that are added to beamline produced in a mainline beamforming process in order to produce output beamlines. | ||||||
