ants.utils.sitk_to_ants

Functions

`from_sitk`(sitk_image)	Converts a SimpleITK image into an ANTsPy image.
`to_sitk`(ants_image)	Converts an ANTsPy image into a SimpleITK image.

from_sitk(sitk_image: SimpleITK.Image) → ANTsImage[source]

Converts a SimpleITK image into an ANTsPy image. Requires SimpleITK.

Parameters:: sitk_image (SimpleITK.Image) – The SimpleITK image to convert.
Returns:: ants_image – The converted ANTsPy image.
Return type:: ants.core.ANTsImage
Raises:: ValueError – If the image dimensionality is unsupported.

Examples

>>> import SimpleITK as sitk
>>> import ants
>>> img = sitk.ReadImage('brain.nii.gz')
>>> ants_img = from_sitk(img)

to_sitk(ants_image: ANTsImage) → SimpleITK.Image[source]

Converts an ANTsPy image into a SimpleITK image. Requires SimpleITK.

Parameters:: ants_image (ants.core.ANTsImage) – The ANTsPy image to convert.
Returns:: sitk_image – The converted SimpleITK image.
Return type:: SimpleITK.Image
Raises:: ValueError – If the image dimensionality is unsupported.

Examples

>>> import ants
>>> ants_img = ants.image_read('brain.nii.gz')
>>> sitk_img = ants.to_sitk(ants_img)
