    • Ultrasound adaptive imaging methods and/or systems provide for modification of waveform generation to drive a plurality of transducer elements. The modification may be based on at least one of contrast ratio or signal to noise ratio as determined with respect to control points in a region of interest. Further, image reconstruction may be performed upon separating, from pulse echo data received, at least a portion thereof received at each ultrasound transducer element from the region of interest in response to the delivered ultrasound energy corresponding to a single frequency of one or more image frequencies within a transducer apparatus bandwidth. The image reconstructed from the separated pulse-echo data corresponding to the single frequency of the one or more image frequencies may be used alone or combined with like image data (e.g., to provide an image representative of one or more properties in the region of interest).
    • 超声自适应成像方法和/或系统提供波形产生的修改以驱动多个换能器元件。 修改可以基于相对于感兴趣区域中的控制点确定的对比度比或信噪比中的至少一个。 此外,可以响应于对应于一个或多个图像频率的单个频率的递送的超声能量,从与所接收的脉冲回波数据分离其在每个超声换能器元件处的感兴趣区域的至少一部分,来执行图像重建 在换能器设备带宽内。 从与一个或多个图像频率的单个频率相对应的分离的脉冲 - 回波数据重建的图像可以单独使用或与相似的图像数据组合使用(例如,提供代表感兴趣区域中的一个或多个属性的图像 )。

    • A method and system of imaging is provided. The system can include an imaging system (10) having at least one probe (120) for transmitting imaging energy into a region (150) of a body (50) and receiving response energy; a display device (170); and a processor (100) operably coupled to the at least one probe and the display device. The processor can generate a first image based on the response energy. The processor can present the first image on the display device. The processor can present on the display device a second image of the same plane or volume as the first image. The first image is different from the second image. The processor can retrieve a designation of a region of interest from a clinician that is associated with one of the first and second images. The processor can compare the first image with the second image for graphical differences, and the processor can present the region of interest on the other of the second image based at least in part on the graphical differences. Other embodiments are disclosed.
