[ITK-users] simple ITK C# show image

[an qin]

Hi, I am new to C# simpleITK and can't find much sample codes. I tried to
read dicom image and display them in simpleITK. The dicom image was read
without a problem. But got an exception when show.

Any suggestion will be appreciated.

Thanks.
Andy

using itk.simple;

namespace TestReadDicom
{
class Program
{
static void Main(string[] args)
{
var myreader = new ImageSeriesReader();
var names =
ImageSeriesReader.GetGDCMSeriesFileNames(@"E:\ImageSet_0.DICOM");
myreader.SetFileNames(names);
var image = myreader.Execute();
VectorDouble imDim = image.GetOrigin();
Console.WriteLine(imDim[0].ToString());
SimpleITK.Show(image);
}
}
}

Hello,

The documentation for the sitk::Show method can be found here:
https://itk.org/SimpleITKDoxygen/html/namespaceitk_1_1simple.html#ac8416e6e7f02dedfe8373b83dbea411d

I suspect that you don’t have Fiji/ImageJ installed, or the method was not able to locate the executable. There are some environment variables that can be set to properly configure it.

The Show method is designed to be a convenience method to launch an external viewer to display data. It is convenient to use in interactive environments such as python or R for a quick display.

SimpleITK provides wrapping for a large number of languages include Python, R, Lua, Tcl, Ruby, Java and C#. Some languages have more examples then others. In general it’s not too hard to figure out how to translate an useful example from one language to another.

You can find a list of basic examples here:

https://itk.org/SimpleITKDoxygen/html/examples.html

And may Python and R notebooks here:

Hope that helps,
Brad
