    • Motion of a region of interest is tracked in medical imaging. For example, velocity information, such as colored Doppler velocity estimates independent of tracking from one image to another image, are used to indicate an amount of motion between the images. The velocity assisted tracking may be used for one dimensional tracking (e.g., for M-mode images), for tracking in two dimensional images, or for tracking between three dimensional representations. As an alternative or additional example, physiological signal information is used to assist in the tracking determination. A physiological signal may be used to model the likely movement of an organ being imaged to control or adjust matching search patterns and limits. The modeling may also be used to independently determine movement or for tracking. The independently determined tracking is then combined with tracking based on medical data or other techniques. The cost function or other metric for determining the sufficiency or a match may include information modeled from or selected as a function of the physiological cycle signal in addition to other matching calculations. The fusion of physiological signal information with image data tracking may improve the tracking.
    • 感兴趣的区域的运动在医学成像中被跟踪。 例如,速度信息,例如独立于从一幅图像到另一幅图像的跟踪的彩色多普勒速度估计,用于指示图像之间的运动量。 速度辅助跟踪可以用于一维跟踪(例如,用于M模式图像),用于在二维图像中跟踪或用于三维表示之间的跟踪。 作为替代或附加示例,使用生理信号信息来辅助跟踪确定。 可以使用生理信号来对被成像的器官的可能运动进行建模,以控制或调整匹配的搜索模式和限制。 建模也可以用于独立地确定运动或跟踪。 然后将独立确定的跟踪与基于医疗数据或其他技术的跟踪组合。 用于确定足够或匹配的成本函数或其他度量可以包括除了其他匹配计算之外,根据生理周期信号建模或选择的信息。 生理信号信息与图像数据跟踪的融合可以改善跟踪。
