DICOM RT-Ion interface for MC simulation

Current version is BETA as of Aug14, 2019

DICOM RT-Ion interface, shortly RTI, is a library to convert treatment planning information in DICOM format into Monte Carlo components on-the-fly such as geometries and beam source. The RTI allows integration of DICOM-RT Ion interface within a MC engine to provide more reliable and consistent performance than with a script-based processing to interpret DICOM information. For the Monte Carlo simulation, TOPAS extensions of geometry and particle source to connect RTI are provided.

DICOM-RT objects utilized in this interface are

• Ion Plan (RTIP)
• Ion Beams Treatment Record (RTIBTR)
• CT image
• RT-Dose

  note: RT Plan is not supported (2019. July 22).

Beamline geometries, gantry and patient coordinate systems, and fluence map are determined from RTIP and/or RTIBTR. CT image and Dose are used only for patient dose calculations.

Getting started

Requirements

• GDCM tested versions are 2.4, 2.6.8, and 3.0.

  (GDCM version 3.0 works with RTI if you compile TOPAS 3.9 from source instead of using the binary package.)

Monte Carlo

• TOPAS are tested for versions 3.1, 3.2, 3.5, 3.7, and 3.9

Tested operating systems

• Mac OS X
  • 10.14.5, clang++ (LLVM version 10.0.1, /usr/bin/c++)
  • 12.6.2, clang++ (LLVM version 14.0.0, /usr/bin/c++) with topas 3.9
  • cmake version 3.24
• Linux
  • Red Hat Enterprise Linux Server release 6.7 g++ (4.9.0)
  • Ubuntu 12.0 with gcc 11
  • Ubuntu 19.10
  • Ubuntu 22.04 (gcc 11.3)

Installation

As RTI is a header only library, copy or download the files to somewhere in your system.

$ cd /<your_sw_path>/
$ git clone https://github.com/topasmc/dicom-interface rti.git

If you are compiling dicom-interface with topas releases ( not from source), you need to use same headers of gdcm that topas used.

$ cd /<your_sw_path>/rti.git
$ tar -zxf gdcm-2.6.include.tar.gz
$ ls gdcm-2.6

Then, go to the directory where your topas is installed.

$ cd /<your_topas_path>/

Add two lines in CMakeList.txt (in TOPAS) as following:

include_directories (
    ${CMAKE_BINARY_DIR}
    ${CMAKE_BINARY_DIR}/extensions
    ${PROJECT_SOURCE_DIR}/Geant4Headers
    ${PROJECT_SOURCE_DIR}/include
    /<your_sw_path>/rti.git/
    /<your_sw_path>/rti.git/gdcm-2.6
)

$ cmake -DTOPAS_EXTENSIONS_DIR=/<your_sw_path>/rti.git/rti/topas/rtion .
$ make -j4

Run a test

$ cd /your_sw_path/rti.git/topas/tutorial/
$ topas beam_view.txt
