摘要： A miniaturized micromachined ultrasonic transducer 100 is disclosed herein for implantation in tissue to achieve high-resolution images. An array of ultrasonic transducers 102 is fabricated in a carrier 700 using integrated circuits (IC) technology. The carrier 700 is micromachined into a needle shape with a cross-section small enough for the array of ultrasonic traducers 102 to be inserted into tissue for high- resolution medical imaging. The length of the probe shank portion 106 of the transducer 100 is dependent on the quantity of transducers 102 to be arranged in the array. Compared with commercial intravascular ultrasonic devices, this micromachined ultrasonic imager is small enough to allow monolithic integration of a flexible silicon ribbon cable 504 for electrical interconnection from the array of transducers to external electronic. With the silicon ribbon cable 504 as the connector for the array of transducers 102, a catheter is not necessary.

摘要： Volumetric ultrasound images are obtained using a two-dimensional array transducer to create multiple beams that diverge in a viewing direction to achieve high display resolution real-time volumetric imaging. In one embodiment, ultrasound echoes in a plurality of beams positioned adjacent each other in the elevational direction are projected onto respective planes. The volumetric image is created by combining the planes of projection for all of the beams. As a result, an image having a high resolution can be created in real-time. The area scanned by the transducer is divided into symmetrically arrayed beams so that echoes located at the same distance from the transducer are at substantially the same depth beneath the transducer. In another embodiment, multiple beams scan in respective ranges of scanning depths, and the elevational divergence angle is reduced for deeper ranges of scanning depths. In another embodiment, multiple intersecting or parallel beams are used to create volumetric images.

摘要： A synthetic focus ultrasound system is described in which individual transducer elements are activated to insonify the image field and the resultant echoes are received by a plurality of elements of the array. The echo signals are stored and the complete echo set is used to produce motion maps for different velocity vectors over the image field. Various ones of the motion maps are used to produce a wide variety of ultrasound image modes, including grey-scale images, colorflow images, and spectral flow displays.

摘要： An ultrasound-imaging system and method is provided that permits an operator to acquire an image of a volume-of-interest in a time critical fashion, that is capable of referencing the volume rendering to a standard two-dimensional imaging mode, and permits the operator to selectively choose a number of display-mode parameters that result in an operator directed view of the volume-of-interest. The ultrasound-imaging system comprises an input device configured to receive a plurality of imaging parameters and a controller in communication with the input device. The ultrasound-imaging system generates an operator-directed transmit-beam scan sequence in response to the imaging parameters and transmits a spatially modified transmit-beam scan sequence over a portion of the volume-scan range of the ultrasound-imaging system. Moreover, the ultrasound-imaging system provides the flexibility for an operator to direct a plurality of operator-configurable multi-dimensional views.

摘要： A two-dimensional array transducer probe is used to image regions of the body that are acoustically obstructed from conventional view by objects such as the lungs or ribs. The probe is located against the body at an acoustic window which provides acceptable ultrasonic transmissivity between the transducer array and the body. While maintaining the probe at its acoustic window, an image plane location is manipulated by adjusting the beam steering directions. The image plane can be tilted in the elevation direction, moved laterally, and/or rotated about a center axis to position the image plane so that the obstructed anatomy is effectively imaged for diagnosis.

摘要： A diagnostic ultrasonic imaging system includes a scanhead having a plurality of transducer elements. A signal combiner, such a time-division multiplexer, is coupled to each of the transducer elements. The signal combiner combines the signals from the transducer elements into a composite signal and couples the composite signal to an ultrasonic processor through a wire or other communication link. A signal separator, such as a time-division demultiplexer, is coupled to the link and recovers from the composite signal each of the signals from the transducer elements.

摘要： A probe for electronic volume data acquisition using ultrasound incorporates a plurality of transducer elements arranged in a two dimensional array having an azimuth direction and an elevation direction. The transducer elements have a first element size in the azimuth dimension and a second element size in the elevation dimension. At least one of the first and second element sizes is at least twice a characteristic wavelength of a waveform used to drive the array of transducer elements, where the characteristic wavelength is defined as the wavelength corresponding to a center frequency of the waveform. Image data is generated in a scanning process using a CAC-BF technique in an azimuth dimension and/or an elevation dimension, to form an ultrasound image line, image plane, or image data cube.
