Target preparation

To begin the optimization process, first the target is prepared. The target may be a 2D matrix, a 3D matrix, or a .stl file. In general, the CALPrepTarget() is used. Run the function with .stl filename (full path to the .stl file) and the z-slicing resolution. This will create a TargetObj which is saved as target_obj here:

% prepare the target (.stl)
verbose = 1;
resolution = 100;
stl_filename = 'C:\...\test.stl';
target_obj = CALPrepTarget(stl_filename,resolution,verbose);

Alternatively, for directly inputting a 2D or 3D matrix, the function should be run as:

% prepare the target (2D matrix)
target_2D = double(phantom(256)>0.01);
target_obj = CALPrepTarget([],[],verbose,target_2D);

% prepare the target (3D matrix)
target_3D = repmat(double(phantom(256)>0.01),[1,1,50]);
target_obj = CALPrepTarget([],[],verbose,target_3D);
