使用 dicom2nifti 转换无法正常工作

Question

我为每位患者准备了一系列 dicom 文件 (.dcm)，我想将其转换为 nii.gz 文件，但是以下转换没有任何反应（甚至是错误信息）...

import dicom2nifti
dicom2nifti.settings.set_gdcmconv_path('C:/Program Files/GDCM 3.0/bin/gdcmconv.exe')
dicom2nifti.convert_directory('M0_1', 'M0_1.nii.gz')

尝试其他方法时出现错误....

import dicom2nifti
dicom2nifti.settings.set_gdcmconv_path('C:/Program Files/GDCM 3.0/bin/gdcmconv.exe')
dicom2nifti.dicom_series_to_nifti('M0_1', 'M0_1.nii.gz')

错误日志：

Traceback (most recent call last):
  File ".\test.py", line 5, in <module>
    dicom2nifti.dicom_series_to_nifti('M0_1', 'M0_1.nii.gz')

    header = dicom_input[0]
IndexError: list index out of range

文件结构：

M0_1
   |----IM-0001-0001.dcm
   |----IM-0001-0002.dcm
   ........
   |----IM-0001-000299.dcm
   |----IM-0001-000300.dcm

环境： windows10, python: 3.6, dicom2nifti2.3.0

我哪里做错了？

或者有没有其他的转换方式？

提前致谢！

我没用过 dicom2nifti，但你可以使用 SimpleITK 将 DICOM 转换为 Nifti。

下面是应该完成这项工作的代码：

import SimpleITK as sitk

reader = sitk.ImageSeriesReader()
dicom_names = reader.GetGDCMSeriesFileNames('M0_1')
reader.SetFileNames(dicom_names)
image = reader.Execute()

# Added a call to PermuteAxes to change the axes of the data
image = sitk.PermuteAxes(image, [2, 1, 0])

sitk.WriteImage(image, 'M0_1.nii.gz')

您可以在此处了解有关 SimpleITK 的更多信息：https://simpleitk.readthedocs.io/

更新：我添加了对 SimpleITK 的 PermuteAxes 的调用以将轴顺序从 X-Y-Z 更改为 Z-Y-X。
