    • The invention provides a method and apparatus for fast volume rendering of 3D ultrasound image, comprising a dividing step, a calculating step, a determining step, a morphological closing operation step and a filling step, wherein each flat grid can be entirely filled by obtaining gray-scale values for all pixels inside the grid through interpolating; for the non-flat grid, the steps of dividing, calculating, determining and filling are performed repeatedly until the non-flat grid is subdivided into atomic grids to calculate gray-scale values for remaining pixels by projection. As the method can be finished in the rear end, no difficulty occurs in the implementation, and no process for being adapted to previous frames is required. Therefore, the method can improve the rendering speed effectively without degrading the quality of image to put 3D ultrasound imaging to the best use.
    • 本发明提供了一种用于3D超声图像的快速体积绘制的方法和装置,包括分割步骤,计算步骤,确定步骤,形态关闭操作步骤和填充步骤,其中每个平面格栅可以通过获得灰色完全填充 通过内插的网格内的所有像素的尺度值; 对于非平坦网格,重复执行分割,计算,确定和填充的步骤,直到非平坦网格被细分为原子网格,以通过投影来计算剩余像素的灰度值。 由于该方法可以在后端完成,所以在实现中不会发生困难,并且不需要适应于先前帧的处理。 因此,该方法可以有效提高渲染速度,而不降低图像质量,使3D超声成像得到最佳的利用。
