摘要： An ultrasound imaging system includes a biplane ultrasound probe and a console. The biplane ultrasound probe includes a sagittal array and a transverse array. The console includes a transmit circuit, a receive circuit, and an image generator. The transmit circuit is configured to control the sagittal and transverse arrays to emit ultrasound signals while the probe is manually rotated and translated. The receive circuit is configured to receive electrical signal produced by the sagittal and transverse arrays in response to the sagittal and transverse arrays receiving echoes produced in response to the corresponding ultrasound signals interreacting with structure. The image generator is configured to construct a three-dimensional image with the electrical signals from the sagittal or transverse array using the electrical signals from both the sagittal and transverse arrays to track the motion of the probe and align scanplanes.

摘要： An apparatus includes a memory device with computer readable instructions and a processor configured to execute the computer readable instructions encoded on the memory device. The processor, in response to executing the computer readable instructions, obtains an ensemble of ultrasound images with diversity in an ensemble dimension, extracts a sub-set of data from each of the images, constructs a data matrix with the extracted data, wherein the data matrix has a dimension of space versus the ensemble dimension, identifies a largest eigenvalue(s) and a corresponding eigenvector(s) in the data matrix, computes a coherent signal projection matrix with the identified corresponding eigenvector(s), filters the data matrix with the coherent signal projection, and generates an ultrasound image with the filtered data matrix.

摘要： A system (1100) includes an ultrasound imaging probe (304) with an elongate shaft (312) including an outer perimeter housing (331), two ends (328, 330) and a long axis (320). The system further includes a channel (326) that extends along the direction of the long axis, is part of the outer perimeter housing, and is configured as a recess of the outer perimeter housing. The system further includes a handle (310) affixed to one of the ends of the elongate shaft. The system further includes a transducer array (322) disposed at another of the ends of the elongate shaft. The transducer array includes one or more transducer elements (324).

摘要： A system (800) includes an acquisition engine (837) that acquires ultrasound data for two or more modes with a first acquisition algorithm, including an image mode and a special mode. A rendering engine (834) employs a first rendering algorithm and displays the image in a main display window (902) and the special mode ultrasound data in a viewport (906) superimposed over the main display window. The acquisition engine acquires ultrasound data for the special mode using a second acquisition algorithm and the rendering engine displays a first portion of the generated special mode ultrasound data over the main display window and a second portion of the generated special mode ultrasound data over the viewport using a second rendering algorithm in response to the system receiving an input signal indicative of a movement of the viewport from a first location of the main display window to a second different position of the main display window.

摘要： An ultrasound imaging system (100) includes a transducer array (102) with plurality of transducer elements (200) configured to transmit an ultrasound signal and receive echoes. Transmit circuitry (104) is configured to excite the transducer elements to transmit the ultrasound signal along a propagation direction. Receive circuitry (106) is configured to receive an echo signal produced in response to the ultrasound signal traversing flowing structure in the field of view. A beamformer (112) is configured to beamform the echo signal and produce a single directional signal at a depth. The directional signal is transverse to the propagation direction of the ultrasound signal. A velocity processor (114) is configured to transform the directional signal to produce a corresponding quadrature signal, estimate a depth velocity component and a transverse velocity component at the depth based on the directional signal and the quadrature signal, and generate a signal indicative of the estimate.

摘要： An apparatus (402) includes an analog beamformer (414) that receives a set of analog RF signals. The set of analog RF signals are generated by a corresponding set of transducer elements (406) receiving ultrasound echo signals. The analog beamformer includes a delay network (416) with a set of phase shifting networks (506). Each phase shifting network of the set of phase shifting networks processes a different one of the analog RF signals of the set of analog RF signals. Each phase shifting network of the set of phase shifting networks adds a delay to the corresponding analog RF signal, producing a set of delayed analog RF signals that are aligned in time. The set of phase shifting networks does not use an inductive element to determine or add the delays. The analog beamformer further includes a summer (504) that sums the delayed analog RF signals, producing an analog beam sum.
