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 to https://imagej.nih.gov/ij/download.html

Make sure to download the bundled with 64-bit Java 1.8.0_112 version

ImageJ Setup

Go to https://imagej.nih.gov/ij/plugins/nifti.html

Download nifti_io.jar

Go to C:\blah\blah\ImageJ\plugins\Input-Output

Delete the existing nifti_io.jar file from the folder

Copy the downloaded nifti_io.jar file into the folder

Restart ImageJ and check if File -> Import -> NIfTI-Analyze is there

If it is there, the plugin was successfully installed

SimpleITK Setup

Find the path where your ImageJ.exe file exists

Open cmd

Type in setx SITK_SHOW_COMMAND "C:\blah\blah\ImageJ\ImageJ.exe"

You should get the message SUCCESS: 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%
