如何将Nifti文件转换为Numpy数组？

Question

我在Nifti文件（.ii.gz）中有3D数组，我想将其保存为3D numpy数组。我使用Nibabel将Numpy转换为Nifti1。我可以反其道而行吗？

Answer 1

来自nipy

import numpy as np
import nibabel as nib

img = nib.load(example_filename)

a = np.array(img.dataobj)

Answer 2

您也可以这样做：

import numpy as np
import nibabel as nib

img_nifti = nib.load(filepath)
img = img_nifti.get_data()
