The NURBS-based HUman Brain (NHUB) Phantom
Based on a segmented MRI dataset of a normal subject (100 structures) including the ability to simulate rigid motion of the brain (3 translation, 3 rotation).
make, or use
CMake (e.g. for
dncat_bin (without arguments) for help:
$ make $ ./dncat_bin Program to produce voxelised phantoms from NURBS torso file input Usage: ./dncat_bin [options] <gen_par> <out_base> Options: -x X translation in mm -y Y translation in mm -z Z translation in mm -X X rotation in degrees -Y Y rotation in degrees -Z Z rotation in degrees Arguments: <gen_par> : general parameter filename. Note that start_slice should be an even number > 1 to avoid artefacts. <out_base> : base string for output files
./dncat_bin test.par resulting_image1
will create a
128x128x128 sample brain image (see
for definitions). The values we have used in this particular example are
somewhat close to a typical anatomic MR study (but this may need to be
better tuned and double-checked for the various regions).
