A Korean institute specialised in atomic energy research, has developed a technology that removes the Compton scattering-induced noise in radiation transmission imaging devices. By using the technology, users will be able to get a higher-resolution image than before. Any organisations in need of such technology can be a potential partner under a license agreement, technical cooperation, and commercial agreement with technical assistance.



Radiation transmission image devices are commonly used in the medical and healthcare fields when diagnosing a symptom. For a more precise diagnosis, sharper images are being preferred.

However, the existing technology has limitations by being unable to segregate the primary signals when the two signals are collected, causing a noise (induced by Compton scattering) to lower the final image quality.

A Korean R&D institute focusing on atomic energy research has developed a technology for removing Compton scattering-induced noise in radiation transmission image devices. The technology will be able to deliver a high-resolution image to the device users, mostly medical professions.

The technology is diverged from an existing technology (PET: Positron Emission Tomography) of which is an imaging technique that uses simultaneous signals to determine the centre of the radiation circle. Unlike PET, the technology uses simultaneous signals to remove the noise signals in a detector. Additionally, it is able to discern Compton scattered gamma rays from the primary signals when they are collected through a different location after scattering.

The technology can be done by following steps:

1) Converting incident radiation into optical signals
2) Separating the optical signals based on their collection time to
determine and discard simultaneous signals
3) Separating the incident optical signals converted through
scintillators if they are re-collected within a reference time,
whereby simultaneous signals are determined and discarded

Any companies or research institutes, interested in medical imaging devices using radiation transmission imaging can be the main partners under the license agreement, technical cooperation and commercial agreement with technical assistance.

Advantages & innovations

Cooperation plus value: 
Benefits of removing Compton scattering-induced noise: -Minimising the impacts of the incident radiation and optical signals on adjacent scintillators -Identifying the simultaneous signal of optical signals based on their collection time data -Improving the quality of final images by removing the simultaneous signals -Enhancing the light yield of scintillators when using a protective film Technical Advancement -The existing technology degraded the quality of an image up to 46% in high density scintillators. The technology increases the quality of the final image by removing the noise, the scintillators of varying density levels, from low to high.
