DICOMTree

A little Julia package for visualizing DICOM file metadata in the form of a tree. The main function is the Tree function, which is simply a dispatch of the eponymous function in the Term.jl package to the DICOMData type in the DICOM.jl package. The package have been tested with CT Scanner, RTDose and RTStruct files.

How to use DICOMTree.jl ?

using DICOM
using DICOMTree

dcm_file = dcm_parse(dcm_path)

Tree(dcm_file, with_keys = false, maxdepth = 2)

Output (with colours in the REPL) :

  • with_keys = true will replace the name with the associated tag (e.g. : (0x0010, 0x0020) if true and PatientID if false). Default is false.

  • maxdepth defines the depth at which the DICOM tree is explored. Default is 2. Note that a high scan depth may take a few seconds to be displayed.

Then, we can focus on a specific tag :

Tree(dcm_file.ROIContourSequence, maxdepth = 3)
