static void convert (const usImagePostScan3D< unsigned char > &image, const double &x, const double &y, const double &z, double &u, double &v, double &w)
 

Detailed Description

Conversion between a position in meters in the space and the equivalent pixel position in the ultrasound image.

  • The following image shows the correspondance between frames (u,v) and (x,y) for post-scan 2D images:
