medpy.io.header.Header

class medpy.io.header.Header(spacing=None, offset=None, direction=None, sitkimage=None)

A medpy header object.

Stores spacing, offset/origin, direction, and possibly further meta information. Provide at least one of the parameters. Missing information is extracted from the sitkimage or, if not supplied, set to a default value.

Parameters:

spacingtuple of floats

the image’s voxel spacing defaults to a tuple of 1.0s

offsettuple of floats

the image’s offset/origin defaults to a tuple of 0.0s

directionndarray

the image’s affine transformation matrix must be of square shape default to the identity matrix

sitkimagesitk.Image

the simple itk image as loaded

__init__(spacing=None, offset=None, direction=None, sitkimage=None)
