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： 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 for making Doppler ultrasound measurements utilizes an ultrasound probe having two transducer arrays oriented at right angles to one another and spaced apart from one another. The first array is used to measure multiple apparent Doppler parameters such as velocity at respective regions within a cross section of a structure such as a blood vessel. The second array is used to measure second apparent Doppler parameters at one of these regions. The first and second apparent Doppler parameters for the same point are used to correct the first apparent Doppler parameters to more nearly equal true velocity or energy.

摘要： A transmit beamformer includes multiple transducers, each responsive to a respective transmit waveform to produce a respective transducer waveform. A transmit waveform generator generates the transmit waveforms, and the transmit waveforms each include multiple frequency components. Progressively higher frequency components of the transmit waveforms are timed to cause corresponding progressively higher frequency components of the transducer waveforms to focus along a line at progressively shorter ranges. In this way, a frequency dependent line focus is achieved.

摘要： An improved device and method for collecting data used for ultrasonic imaging. The data is gathered over numerous transmit and echo receive cycles, or iterations and combined into a synthetic acquisition representing a complete echo characteristic acquisition. At each iteration, only a portion, or subset, of the echo characteristic is sampled and stored. During the iterations, the portion of the echo characteristic that is measured and sampled is varied by changing the relative sampling instants. That is, the time offset from the transmission to the respective sampling instant is varied. The sample sets representative of the entire echo characteristic are then compiled from the multiple subsets of the ultrasonic transmissions.
