Primary LanguageC++

The NURBS-based HUman Brain (NHUB) Phantom

DOI brain_phantom-hits

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).

NHUB

Usage

(Re)compile using make, or use CMake (e.g. for Visual Studio). Then run 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

Examples

./dncat_bin test.par resulting_image1

will create a 128x128x128 sample brain image (see test.par 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).
