摘要： A method for generating a dedicated M beam profile which allows the user to offset the beam origin or steering angle for the cardiology application; display the M line with or without the B mode on the screen; and the M line does not use any of the same beam profile from B line, or is created out of the acquired B lines as a virtual M line.

摘要： An ultrasound imaging system capable of generating a flow image from B-mode echo frames. For each location in a target region, phase information is derived from the B-mode echo frames, and frame-to-frame changes in the phase information are processed to detect the presence of fluid flow at that location. A demodulator receives the B-mode echo frames and demodulates them into baseband signal components from which the phase information is derived. Preferably, the demodulator is highly accurate and robust, such that frame-to-frame changes in the phase information are reliably measured. From the reliably measured phase information, a phase shift metric is then computed and thresholded by a user-adjustable threshold value. Flow is present if the phase shift metric is greater than the threshold value and is absent otherwise. The user may adjust the threshold value in real time through an input device, such as a knob or keyboard, to increase or decrease the flow sensitivity as desired and/or to eliminate the slow-moving clutter. Together with a B-mode image, the flow image is provided to an ultrasound display. For further clutter removal, the flow image may be suppressed for those locations having B-mode intensities below a predetermined lower threshold or above a predetermined upper threshold. The provided system provides a real-time flow image having the same high frame rate, spatial resolution, and coverage area as the B-mode image.
摘要翻译：能够从B模式回波帧产生流动图像的超声成像系统。对于目标区域中的每个位置，从B模式回波帧导出相位信息，并且处理相位信息中的帧到帧的改变以检测该位置处的流体流的存在。解调器接收B模式回波帧并将其解调为从其导出相位信息的基带信号分量。优选地，解调器是高度精确和鲁棒的，使得相位信息中的帧到帧的改变被可靠地测量。从可靠测量的相位信息中，然后计算相移度量并通过用户可调阈值阈值。如果相移量度大于阈值，则存在流量，否则不存在。用户可以通过诸如旋钮或键盘的输入装置实时地调整阈值，以根据需要增加或减少流量灵敏度和/或消除慢移杂波。与B模式图像一起，将流动图像提供给超声显示。为了进一步去除杂波，可以抑制具有低于预定下限阈值或高于预定上限阈值的B模式强度的位置的流动图像。所提供的系统提供具有与B模式图像相同的高帧率，空间分辨率和覆盖区域的实时流图像。
