摘要： A foreground image is overlaid over a background image on a visual display. Specifically, an ultrasound signal is transmitted toward a target to be displayed in two dimensions. Echoes of the ultrasound signal are received from the target. Two-dimensional target data acquired from the received echoes are stored. The two-dimensional target data are presented on the visual display as a background image. Part of the target data are overlaid over the background image as a foreground image on the visual display. The size of the foreground image vis-a-vis the background image is changed by the user to permit better observation of an area of interest. Preferably, the size of the foreground image is changed without changing the area occupied by the foreground image on the visual display, which permits the invention to simulate the action of a magnifying glass. The user moves a cursor on the visual display to the center of an area of interest. The user then opens up a window about the cursor to define the length and width of the foreground image on the visual display, while observing the target data presented on the visual display. The user can then magnify the size of the foreground image centered on the cursor, chance the dimensions of the window, and/or change the location of the cursor to move the area of interest, without disturbing the background image.
摘要翻译： 前景图像覆盖在视觉显示器上的背景图像上。 具体地说，向目标传送超声波信号以二维显示。 从目标接收超声信号的回波。 存储从接收的回波获取的二维目标数据。 二维目标数据作为背景图像呈现在视觉显示器上。 目标数据的一部分在视觉显示上作为前景图像叠加在背景图像上。 前景图像相对于背景图像的大小由用户改变以允许更好地观察感兴趣的区域。 优选地，改变前景图像的尺寸而不改变视觉显示器上的前景图像占据的面积，这允许本发明模拟放大镜的动作。 用户将视觉显示上的光标移动到感兴趣区域的中心。 然后用户打开关于光标的窗口，以在观察视觉显示器上呈现的目标数据的同时定义视觉显示器上的前景图像的长度和宽度。 然后，用户可以放大以光标为中心的前景图像的尺寸，机会窗口的尺寸，和/或改变光标的位置以移动感兴趣的区域，而不会干扰背景图像。
