get_mask_dcmseg

formatreader.get_mask_dcmseg(filename: str, mask_id=[0], n_interp=10, smooth_slices=True)

Retrieves the surface points of the 3D volume defined by the masks of a DICOM seg file.

Parameters:

• filename (str must be .dcm format) –

• mask_id (int default = 0. If 0 all masks are merged into a single point cloud) –

• n_interp (int) – Number of slices interpolated between every consecutive original slices. Default = 10.

• smooth_slices (bool) – If True, binary slices are smoothed via erosion/dilation operations. Default = True

Returns:

• contours (Numpy array) – Contains the contours of every slice in voxel coordinates.

• covers (Numpy array) – Contains the points from the top and bottom slices. Needed to close the .stl geometry.

• transf_mat (Numpy array) – Transformation matrix to convert from voxel coordinates to space coordinates.
