我们已经开发了超分辨率回波描记术，从高帧率回波描记仪记录的时间序列回波图中可视化内脏器官的瞬时速度和加速度。该方法的算法包括两个回波图的相减，将差值除以第一回波图的亮度梯度，并将结果归一化为两个回波图之间的时间间隔。将速度或加速度分类为一些合适的颜色并叠加在原始B型图像上。运动器官的功能诊断可以通过可视化瞬时速度来进行。在心脏的情况下，运动功能减退可以通过代表瞬时速度的彩色部分的值和变化与正常心脏区分开。这也可以应用于肝脏以观察脉动运动。通过可视化瞬时加速度，可以检测速度的增加或减少。可以观察心脏中的搏动定时和心律失常的位置。这种方法有可能有助于非侵入性的功能和特性的评估。
We have developed super-resolution echography to visualize instantaneous velocity and acceleration of internal organs from time-series echograms recorded by a high-frame-rate echograph. The algorithm for this method involves subtraction of two echograms, dividing the difference by the brightness gradient of the first echogram, and normalization of that result by the time interval between the two echograms. Velocity or acceleration is classified into some suitable colors and superimposed on the original B-mode image. Functional diagnosis of moving organs can be made by visualizing instantaneous velocity. In the case of the heart, hypokinesis can be distinguished from a normal heart by the value and the variation of colored parts representing instantaneous velocity. This can also be applied to the liver to observe pulsatile motion. By visualizing instantaneous acceleration, increase or decrease of velocity can be detected. Throb timing and the location of arrhythmia in a heart can be observed. This method has the possibility of contributing to noninvasive functional and characteristic evaluation.
