python sitk.show()与imageJ结合使用常见的问题

在python中配置simpleITK时，遇到了以下这个问题。

simpleITK已经通过pip install安装，但是sitk.show()功能无法正常使用，类似如下

实例代码

import SimpleITK as sitk
import sys
import os
example = sitk.ReadImage("filename")
sitk.show(example)

在sitk.show()这一步会出现以下错误

“Traceback (most recent call last): File “”, line 1, in sitk.Show(image) File “C:\Python27\lib\site-packages\SimpleITK.py”, line 4158, in Show return _SimpleITK.Show(*args, **kwargs) RuntimeError: Exception thrown in SimpleITK Show: …………\Build\ITK\SimpleITK-0.7.1\Code\IO\src\sitkShow.cxx:463: sitk::ERROR: Error in administrating child process: [参数错误。]”

原因是SimpleITK的图像显示功能是通过类似ITK-snap，ImageJ进行实现的，所以在进行sitk.show()之前，需要对此进行设置才能正常实现。

这里参考stack overflow别人给的意见https://stackoverflow.com/questions/43215774/can-not-linksimpleitkshow-with-fiji

ImageJ Installation Go tohttps://imagej.nih.gov/ij/download.html Make sure to download thebundled with 64-bit Java 1.8.0_112version ImageJ Setup Go tohttps://imagej.nih.gov/ij/plugins/nifti.html Downloadnifti_io.jar Go toC:\blah\blah\ImageJ\plugins\Input-Output Delete the existingnifti_io.jarfile from the folder Copy the downloadednifti_io.jarfile into the folder Restart ImageJ and check ifFile – Import – NIfTI-Analyzeis there If it is there, the plugin was successfully installed SimpleITK Setup Find the path where yourImageJ.exefile exists Opencmd Type insetx SITK_SHOW_COMMAND “C:\blah\blah\ImageJ\ImageJ.exe” You should get the messageSUCCESS: Specified value was saved Check if everything works Restart your text editor or IDE (if it was already open) Run your code

​​​​​​除了下载ImageJ操作，另外的很简单。

• 在环境变量里面添加SITK_SHOW_COMMAND ，以imageJ为例，路径指向ImageJ-win64.exe
• 在环境变量中的path中添加%SITK_SHOW_COMMAND%
