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.我可以这样做吗？

Answer 1

从 nipy

import numpy as np
import nibabel as nib

img = nib.load(example_filename)

a = np.array(img.dataobj)

Answer 2

您还可以这样做：

import numpy as np
import nibabel as nib
    
img_nifti = nib.load(filepath)
img = img_nifti.get_fdata()
