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.
