How to read DICOM files into ImageJ?

  • ImageJ has built-in support for reading some kinds of DICOM files. Try File  › Open and see how it goes.
  • The Bio-Formats plugin supports some kinds of DICOM files, too. Bio-Formats is available in the Fiji distribution of ImageJ. Try File  › Import  › Bio-Formats.
  • The Tudor Dicom Tools plugin suite can read and write many kinds of DICOM, and provide some support for working with DICOM metadata structures.

How to save DICOM files from ImageJ?

The Tudor Dicom Tools provide basic support for saving as DICOM.

How to work with DICOM headers from a script?

An example of using the DicomTools.getTag() method from JavaScript:

importClass(Packages.ij.IJ)
importClass(Packages.ij.util.DicomTools)
imp = IJ.openImage("http://wsr.imagej.net/images/ct.dcm.zip"); 
studyDescription = DicomTools.getTag(imp, "0008,1030"); 
imagePosition = DicomTools.getTag(imp, "0020,0032"); 
pixelSpacing = DicomTools.getTag(imp, "0028,0030"); 
print("Study Description: "+ studyDescription); 
print("Image Position: "+imagePosition); 
print("Pixel Spacing: "+ pixelSpacing); 

How to work with DICOM headers from a macro?

See these macro functions:

An example using getInfo():

open("http://wsr.imagej.net/images/ct.dcm.zip"); 
studyDescription = getInfo("0008,1030"); 
imagePosition = getInfo("0020,0032"); 
pixelSpacing = getInfo("0028,0030"); 
print("Study Description: "+ studyDescription); 
print("Image Position: "+imagePosition); 
print("Pixel Spacing: "+ pixelSpacing);
