DCMView

Light weight DICOM viewer on macOS

Build DCMTK for Standalone macOS App

Required tools

• Xcode (or LLVM-clang build system)
• cmake (use homebrew to install it)

A note on dicom data dictionary

Almost all DCMTK tools and libraries require the so-called DICOM data dictionary, i.e., information from part 6 of the DICOM standard, to be available in order to map the attribute tags to their associated Value Representation (VR), Value Multiplicity (VM) and attribute name (official keyword).

The data dictionary can either be

• loaded from file (default on Unix systems), or
• built into the respective tool / dcmdata library (default on Windows systems).

The default behavior can be changed using appropriate configuration options.

To configure dicom data dictionary to be built into the library on Unix systems

When building with CMake, the related option is:

• DCMTK_DEFAULT_DICT

Possible values for this option are:

• "external": Compile with external default dictionary
• "builtin" : Compile with built-in default dictionary
• "none" : Compile without any default dictionary (same as "disable")

How to build dcmtk

Get source code from GitHub repository

> mkdir work && cd work
> git clone git@github.com:DCMTK/dcmtk.git
> mv dcmtk dcmtk-src

Build

> mkdir dcmtk-build && cd dcmtk-build
> cmake -DDCMTK_DEFAULT_DICT="builtin" ../dcmtk-src
> make -j
> make DESTDIR=../dcmtk install
> cd ../dcmtk && mv ./usr/local/* ./
> rm -rf ./usr

After building the DCMTK, move the three directories, dcmtk, dcmtk-build, and dcmtk-src to the project directory.
