摘要： Method and apparatus for enhancing the clarity of diagnostic information in real-time B-mode and M-mode ultrasound displays including a beamformer (1) for acquiring ultrasound signals, a signal processor for processing the ultrasound signal with programmable dynamically variable non-linear filters (4, 7), and a display (9) for viewing the ultrasound signals. The non-linear filters (4, 7) may process video signals in range along each ultrasound scan line or azimuthally along multiple ultrasound scan lines of a two-dimensional B-mode image. The non-linear filters (4, 7) also can be two-dimensionally programmable for processing video signals both in range along each ultrasound scan line and azimuthally along multiple ultrasound scan lines over regions of a two-dimensional B-mode image. The non-linear filter (4, 7) may be responsive to a local signal measurement and to spatial positions in a B-mode image for control of filter parameters. The non-linear filter (4, 7) can also be programmable to accomodate variable system characteristics for particular imaging applications.

摘要： An ultrasonic receive beamformer (10) includes transducers (11) forming receive signals that are applied to sub-array processors (12). Each sub-array processor includes at least one analog preconditioning circuit (13), phase shifter (14) and a summer (16), 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 via an analog-to-digital converter (18) to a respective beamformer processor (20). 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 beam former 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.

摘要： A method and an apparatus are provided for dynamic, real time adaptive focussing (600) for ultrasound imaging. Aberration delay correction values, corresponding to an aberration region in an imaged subject, are measured (601) concurrently during B-mode imaging scan lines and updated at the scan line rate. The measured aberration delay correction values (Ek, L, Rk) are then applied concurrently (560) to correct the focus of all transmitted and received ultrasound scan lines, regardless of the imaging mode, scan geometry, or imaging frequencies.

摘要： The energy, power or amplitude of Doppler or time shift information signals (line 252) is compared to a threshold (lock 54) in order to select a large or small weighting factor (a(long) or a(short)) for temporal persistence. In the event of a "flash" signal or strong arterial flow signal, a small weighting factor (a(short) is chosen to reduce the extent of temporal persistence via feedback (line A) of the averaged value for the prior frames so that the effect of the "flash" or strong flow signal would quickly dissipate in the imaging of subsequent frames (y(n)) and good temporal resolution preserved for the current frames (x(n)), while low energy flow signals would cause a large weighting factor (a(long)), to be selected to improve the signal-to-noise ratio of low energy signals. Similar effects can be achieved by clipping the signals to not exceed a certain threshold.
摘要翻译：将多普勒或时移信息信号（线路252）的能量，功率或振幅与阈值（锁54）进行比较，以选择用于时间持久性的大或小的加权因子（a（长）或（短））。在“闪光”信号或强动脉信号的情况下，选择小的加权因子（a（short））以通过对于先前帧的平均值的反馈（线A）来减小时间持续的程度，使得 “闪光”或强流量信号的影响将在随后的帧（y（n））的成像中快速消散，并且为当前帧（x（n））保留良好的时间分辨率），而低能量流信号将导致大的加权因子（a（long）），以提高低能量信号的信噪比，通过将信号削波为不超过某个阈值可以实现类似的效果。

摘要： An ultrasonic receive system includes two receive beamformers. A first receive beamformer (R-100) is optimized for imaging modes such as B-mode and color resolution and wide bandwidth, while the accompanying second receive beamformer (A-400) has a wide dynamic range and is dedicated for use in acquiring spectral Doppler information, which is typically narrowband compared to imaging information. The second receive beamformer achieves the sensitivity and low-noise performance of a dedicated single-channel pencil probe instrument yet it also performs electronic beam steering. Both receive beamformers can operate through a common transducer array, thereby increasing exam efficiency and permitting registration of sprectral Doppler information with a B-mode or color Doppler flow image.

摘要： Method for scanning a field of view using a scan format, wherein the carrier frequency of the imaging pulse is higher in the center of the field of view than at the edges. The frequency variation can be accomplished on transmit by modulating appropriately delayed programmable initial waveform information samples with a programmable carrier frequency (T-102). This results in a pulse transmitted into the body whose frequency is highest in the center portion of the scan, and is reduced in a controlled fashion as the steering angle is increased in order to mitigate grating lobe artifacts. The technique preserves signal energy because modulation merely translates the signal in frequency substantially without modification of the pulse shape itself. The technique is also useful on receive, wherein demodulation to or near baseband followed by post-beamformation predetection remodulation (R-100) can correct for systematic scan-line-to-scan-line phase variations to ensure scan-line-to-scan-line phase coherency for subsequent coherent processing across scan lines or for coherent image formation (R-26) using the phase and amplitude information from multiple beams.
摘要翻译：使用扫描格式扫描视野的方法，其中成像脉冲的载波频率在视野的中心高于边缘的中心。可以通过用可编程载波频率（T-102）调制适当延迟的可编程初始波形信息采样来实现频率变化。这导致脉冲发射到身体中，其频率在扫描的中心部分中的频率最高，并且随着转向角度增加而以受控的方式减小，以便减轻光栅叶片伪像。该技术保留信号能量，因为调制仅基本上平移信号的频率，而不改变脉冲形状本身。该技术对于接收也是有用的，其中对基带之后或接近基带的解调后波束形成预检测重新调制（R-100）可以校正系统扫描线到扫描线相位变化，以确保扫描线对扫描用于使用来自多个波束的相位和幅度信息的扫描线之间的后续相干处理或相干图像形成（R-26）的相位相干。

摘要： An ultrasonic imaging system (10) includes an ultrasonic transducer (16) having an image data array (18) and a tracking array (20) at each end of the image data array (18). The tracking arrays (20, 22) are oriented traversely to the image data array (18). Images from the image data array (18) 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 (38) based on frames of data from the tracking arrays (20, 22). As the transducer (16) is rotated about the azimuthal axis of the image data array (18), features of the target remain within the image planes of the tracking arrays (20, 22). 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： This invention is an apparatus for imaging an object using a transducer array (1) for transmitting one or more beams (2a, 2b) 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 (a) receive scan lines on which a signal was sensed, (b) transmit scan lines on which a signal was directed, or (c) 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.
