Hi everybody,

I need help to create a stack of DICOM-Files. As far as I open a single DICOM-File, I get an excellent quality image (16 bit displayrange -900 - 2300) and I am able to use window and level settings as it should be for medical images. Now I am using the following code:
...
dicomFile.open("http://"+webserver+"/image"+i+".dcm");
// this is a good quality picture
dicomFile.show();

// now creating stack
imageStack = dicomFile.createEmptyStack();

// add Image to stack
imageStack.addSlice(dicomFile.toString(),dicomFile.getProcessor());
                                               
ImagePlus myImgPlus = new ImagePlus(studyUID,imageStack);

// this is a low quality image (why?)
myImgPlus.show();
...


When I have created a stack as shown in the code above, the dicom-images have a low quality (e.g. displayrange 124-3324). What is the problem? Please help me?

Thanks in advance and kind regards
