摘要： The present invention provides a microfabricated ultrasonic transducer with curvature. The curvature is made possible by thinning the substrate such that it is flexible enough to be mounted on an assembly with the desired curvature. In one aspect of the invention, the substrate can contain electronic circuits. In another aspect, the assembly mounting can incorporate curved damping materials that serve to remove undesirable substrate modes.

摘要： An ultrasonic imaging system includes an ultrasonic transducer having an image data array and a tracking array at each end of the image data array. The tracking arrays are oriented transversely to the image data array. Images from the image data array are used to reconstruct a three-dimensional representation of the target. The relative movement between respective frames of the image data is automatically estimated by a motion estimator, based on frames of data from the tracking arrays. As the transducer is rotated about the azimuthal axis of the image data array, features of the target remain within the image planes of the tracking arrays. Movements of these features in the image planes of the tracking arrays are used to estimate motion as required for the three-dimensional reconstruction. Similar techniques estimate motion within the plane of an image to create an extended field of view.

摘要： A diagnostic medical ultrasonic imaging method and system form first and second signals as a function of the Nth power of the absolute value of first and second ultrasound receive signals. These receive signals are associated with respective first and second transmit pulses that differ in phase and are both associated with overlapping or nearby regions of a subject. A combined signal is formed as a function of the difference between the first and second signals. The low pass component of the absolute value of this combined signal is then applied to an image processor. This low pass component, depending upon the value of N, can correspond to the second harmonic component of the combined receive signals, to the product of the fundamental and second harmonic components of the combined receive signals, and other combinations of fundamental and harmonic components.

摘要： An ultrasound imaging system is programmed to acquire first ultrasonic image frames intermittently. These first frames, typically triggered frames synchronized with a selected portion of an ECG cycle, are optimized for high image quality of a contrast agent included in the tissue. The imaging system automatically acquires second ultrasonic image frames between at least some of the first frames. The second image frames are typically locator frames which are optimized for reduced degradation of the contrast agent. More of the second frames are acquired per unit time than first frames, and both the first and second frames are displayed, either superimposed over one another or in side-by-side relationship. In this way the user is provided with substantially continuous transducer locating information, yet contrast agent destruction between acquisitions of the first, triggered frames is reduced or eliminated.

摘要： A method and apparatus for quantifying and displaying ultrasound signals in an ultrasonic system are provided. A first signal value for each of at least one spatial location in a region of interest is acquired at a first time, and the signal values are summed to obtain a first surface integral value. A second signal value for each of said at least one spatial location in said region of interest is acquired at a second time, and the second signal values are summed to obtain a second surface integral value. The first surface integral value is summed with the second surface integral value to obtain a time based integral. The time based integral is displayed. Other quantities based on any of various ultrasound parameters, such as Doppler energy, Doppler velocity and B-mode intensity, are calculated and displayed as quantities or as waveforms as a function of time. Furthermore, various comparisons of quantities and waveforms are provided. Image plane data or other ultrasound data are used in the calculations. Finally, a histogram data structure is provided to aid calculation of the various quantities.

摘要： The system described ultrasonically images a target with energy spreading transmissions. Generally, ultrasonic energy corresponding to a line focus is transmitted into a target at a fundamental center frequency. The target may or may not include contrast agents. In either case, echoes are received at a harmonic of the fundamental center frequency. Echoes are also received at the fundamental center frequency. The echoes received at the harmonic center frequency are efficiently compounding with the echoes received at the fundamental center frequency.

摘要： A method and apparatus are provided for imaging an object using a transducer array for transmitting one or more beams that are steered and/or translated to transmit scan lines for multiple excitation events so as to scan a field of view of the object, for sensing received signals reflected from the object after each excitation event on one or more receive beams on receive scan lines, and for transducing those sensed received signals into corresponding electrical signals. The method and apparatus is additionally for acquiring and storing coherent samples retaining both phase and amplitude information of those electrical signals obtained on the receive scan lines throughout at least a portion of the field of view, and for combining stored coherent samples associated with distinct receive beams to synthesize new coherent image samples aligned on synthetic scan lines which are distinct from any one of (1) receive scan lines on which a signal was sensed, (2) transmit scan lines on which a signal was directed, or (3) transmit scan lines and receive scan lines. The method and apparatus is further for detecting the synthesized coherent image samples and displaying or recording the resulting image field.

摘要： An ultrasonic receive beamformer includes transducers forming receive signals that are applied to sub-array processors. Each sub-array processor includes at least one phase shifter and a summer, and each phase shifter is responsive to at least one of the transducer signals to shift the transducer signal by a respective phase angle and to apply the phase shifted transducer signals to the summer. Each of the summers supplies a summed sub-array signal to a respective beamformer processor. The phase angles for any one of the sub-array processors form a sum substantially equal to zero. Furthermore, the phase angles for any one of the sub-array processors are independent of the time delay of the respective digital beamformer processor. The time resolution of the time delay of the digital beamformer processors is substantially as fine as the time resolution of the phase angles of the phase shifters. The phase angles of the phase shifters are updated at a slower rate than the focusing update rate of the beamformer processors. Quadrature filter network and heterodyning circuit implementations of the phase shifters are disclosed.
