Series Type: Ground Truth

The ground truth pipeline simply resamples the input ground truth images to a specified resolution. Individual NIFTI images are output for each ground truth quantity in the input image.

All parameters have defaults if omitted; the default parameters result no motion and a resampled matrix of [64, 64, 12].

Images generated by the Ground Truth pipeline will be stored in a subdirectory names “ground_truth”.

Single value parameters

The following parameters are applied to every volume that is generated by the DRO.

acq_matrix

(array of integers, optional) A 3-entry array defining the acquisition matrix size [Ni, Nj, Nk]. Defaults to [197, 233, 189].

rot_z

(float, optional) Rotation of the ground truth model in world space about the z-axis in degrees. See TransformResampleImageFilter for implementation details. Defaults to 0.0.

rot_y

(float, optional) Rotation of the ground truth model in world space about the y-axis in degrees. Defaults to 0.0.

rot_x

(float, optional) Rotation of the ground truth model in world space about the x-axis in degrees. Defaults to 0.0.

transl_x

(float, optional) Translation of the ground truth model in world space along the x-axis in mm. Defaults to``0.0``.

transl_y

(float, optional) Translation of the ground truth model in world space along the y-axis in mm. Defaults to 0.0.

transl_z

(float, optional) Translation of the ground truth model in world space along the z-axis in mm. Defaults to 0.0.
