dosma.core.numpy_routines.stack¶

dosma.core.numpy_routines.stack(xs, axis: int = - 1)[source]¶

Stack medical images across non-spatial dimensions.

Images will be auto-oriented to the orientation of the first medical volume.

Parameters

xs (array-like[MedicalVolume]) – 1D array-like of aligned medical images to stack.
axis (int, optional) – Axis to stack along.

Returns

The stacked medical image.

Return type

MedicalVolume

Note

Unlike NumPy, the default stacking axis is -1.

Note

Headers are not set unless all inputs have headers of the same shape. This functionality may change in the future.

Examples

>>> mv = dm.MedicalVolume([[[0,1,2,3]]], affine=np.eye(4))
>>> np.stack([mv, mv], axis=-1)  # Stacks along last axis.
MedicalVolume(volume=[[[[0 0], [1 1], [2 2], [3 3]]]])
