simpleITK读取nii遇到ITK only supports orthonormal direction cosines的错误

前言

有些nii/nii.gz的文件在使用simpleITK读取时会遇到ITK only supports orthonormal direction cosines的错误，这个时候就需要进行修复

代码

file_path = "001.nii.gz"
try:
    image = sitk.ReadImage(file_path)        
except:
    print(f'cosines problem occures, try to fix it...')
    img = nib.load(file_path)
    qform = img.get_qform()
    img.set_qform(qform)
    sform = img.get_sform()
    img.set_sform(sform)
    nib.save(img,file_path)
    image = sitk.ReadImage(file_path) 
    print(f'now we have fixed it!')

print(image.GetSize())
