The Image Points graph is used to create a matrix which represents the part of investigation made by the specific emission of the Ultrasound Probe. The rows of this matrix have incremental values which represents our values used to compute delay for the virtual sources. It is dependent on the investigation depth and the incremental investigation which we want to perform (based on our sampling frquency).
- Graph Inputs:
- start_positions: the position which we start the investigation in cartesian coordinate;
- directions: X-Y-Z values of propagation of the spherical or planar wave emitted;
- samples_arange: array with the index of the rf-data;
- Graph Outputs:
- Image Points: A Nx4 matrix which represents our points to analyze;
