Constructor Detail

MTFphantom

public MTFphantom(int x,
          int y,
          double r1,
          double r2,
          float cylinderDensity,
          float beadDensity)

The constructor takes two arguments to initialize the grid. The cylinder will be in the center and have a radius of r1% of the x-dimension. Thus we recommend a grid size that is uniform in both directions. The outer beads will be at a circle defined by radius of r2% of the r1 radius.

Parameters:

x - Size in X direction

y - Size in Y direction

r1 - Cylinder radius as a fraction of the X size

r2 - Outer bead radius as a fraction of the cylinder radius

cylinderDensity - Density value for the cylinder

beadDensity - Density value for the beads
