Livermore Computed Tomography Input Output software (LCTIO)

Tools included

Command line tools

• retiff

Python package

• lctio

Getting Started

Install the lctio Python package for command line tools and importable library modules. You could download this repository, but if you are installing into a Python environment with internet access, you can use the pip command to automatically download the package from https://pypi.org/project/lctio/

Example:

# Create and activate a Python virtual environment named "myvenv" (optional)
python3 -m venv myvenv
. myvenv/bin/activate
python -m pip install --upgrade pip

# Use `pip` to install the package from pypi.org
pip install lctio

Command line help for the provided tools is available with the --help option.

retiff --help

Scope

The software includes code for Python, C/C++, and Java (and other languages, as needed) to support interoperability between tools and data formats commonly used for radiography and computed tomography at LLNL and elsewhere.

The software repository is a collection of file readers and writers, converters, visualization software plugins, and data validation tools, aimed at supporting users of LLNL NDE software and CT data.

In addition to industry-standard data formats, LLNL traditionally uses several less common formats that have been described in public documentation, but without supporting public software.

This is the first public release of reference software for the file formats and data structures described in LLNL-TM-684438, the LLNL CT Standard, version 2. Supported data formats from this standard include

• SDT/SPR
• SCT
• phantom description language
• bad pixel map
• spectrum data file

Software tools also help to apply specific metadata, schema, and workflow conventions for more general file formats such as TIFF, RAW, and HDF5.

Additional formats and protocols may be implemented, as needed, to support interoperability with common software such as ImageJ and Fiji, or conversion to and from file types, or other open data standards.

LLNL-specific data structures and file formats may be refined or updated in conjunction with updates to the LLNL CT Standard.

The object modeling language may be expanded as necessary to support conversion to and from other open 3D modeling standards, such as the STL format used in Computer Aided Design.
