Optica Imaging Congress

Radiographic Imaging and Tomography (RadIT)

2024 Rationale

Radiographic Imaging and Tomography (RadIT) use different forms of ionizing radiation, such as X-rays, gamma-rays, energetic electrons, positrons, protons, neutrons, muons, to image both transparent and opaque objects to visible light. The growingly interdisciplinary field of RadIT shares detectors, optics, image processing algorithms with optical imaging and tomography. The building blocks of the RadIT include the radiation sources, methods and modalities to collect data, radiation detectors, RadIT data processing and interpretation, modeling and applications. The examples of X-ray sources include the cathode-tube X-ray sources, km-long accelerators, synchrotrons and X-ray free electron lasers. Other sources of ionizing radiation, such as charged particles (such as protons and muons) and charge-neutral particles (such as neutrons and neutrinos), have opened up new vistas into objects large and small. X-ray films have largely become obsolete due to the introduction of storage phosphor plates, aSi detectors, CCD cameras and lately CMOS imaging sensors. Many of these modalities use a multi-step detection mode where radiation is first converted to visible light and then detected using optical methods. Data and information science, including quantum information science, have breathed new life into radiography in the last decade. Traditional X-ray, charged particle and neutron radiography R&D have been driven by medicine, non-destructive testing and security applications. The latest thrusts of growth come from machine vision, additive manufacturing, microelectronics and digital twins. The RadIT conference, as a part of the Optica Imaging Congress, provides an interdisciplinary forum to bring together world leaders and newcomers alike, and to jointly explore the synergies among visible light, X-rays and other forms of illumination in radiography, imaging, tomography and applied optics and data science.


The scope of RadIT’24 includes, but is not limited to:

  • RadIT of different photon/particle modalities such as X-rays, gamma-rays, neutrons, electrons, positrons, protons and muons and multi-modal RadIT
  • Penetrating radiation source, target, optics and detector hardware integration
  • Spatial, temporal resolution, dose reduction, scan time reduction and other imaging/radiography metrics enhancement through innovative applications of fundamental principles, new image-forming materials and structures, including nanomaterials, flat optics, other metamaterials and metastructures, additively manufactured materials and structures
  • New radiography principles due to source coherence, detection correlations and quantum mechanics
  • New RadIT modalities enabled by pulsed high-power lasers, Compton X-ray sources
  • Computation and data methods such as efficient algorithms for data reduction (offline and in real-time), machine learning and automated reduction of massive data and data-driven image and tomography models such as digital twins
  • Novel applications in medicine, non-destructive testing, machine vision, additive manufacturing, metaverse, micro-electronics, low Earth orbit and beyond.
