Revolutionizing Radiation Detection with Diamonds

In an extraordinary advancement for the medical and scientific fields, Orbray Co., Ltd. has unveiled the world's largest single crystal diamond radiation detector. Utilizing an innovative proprietary technology, this detector showcases exceptional capabilities and remarkable durability, paving the way for advancements in radiation diagnostics and therapy.

The Unique Properties of Diamonds

The diamond, a gem traditionally associated with beauty, has properties that make it highly suitable for radiation detection. Its remarkable radiation hardness ensures that it can withstand high-radiation environments without degradation. Furthermore, the atomic composition of diamonds closely resembles that of biological tissues, making them especially relevant for medical applications, such as x-ray diagnostics and radiation therapy.

Orbray's diamond radiation detector is capable of delivering high-precision measurements across various radiation types. This includes low-energy diagnostic x-rays and high-energy therapeutic x-rays, enabling a plethora of applications in healthcare and experimental physics.

Progress in Diamond Technology

Historically, the utilization of diamonds in radiation detection was limited to selected natural diamonds until advancements in the 1990s made way for enhanced methods. The advent of chemical vapor deposition (CVD) technology opened new doors, allowing for the synthesis of high-purity diamonds that significantly boost detector performance. Single-crystal CVD diamonds, in particular, offer high sensitivity and exemplary spectral characteristics compared to their polycrystalline counterparts, which, while offering increased sensitivity through a larger detection area, fall short in spectral performance.

Collaboration and Development

In 2021, Orbray broke new ground by developing a 2-inch diameter, high-quality free-standing diamond substrate, employing its unique step-flow growth technique. This diamond has since been the backbone for radiation detectors developed in collaboration with leading academic institutions, including Tokyo Metropolitan University, Tohoku University, and Osaka University. These collaborations have resulted in devices that demonstrate high sensitivity and quality spectral characteristics ideal for x-ray systems used in medical environments.

The innovative design allows these detectors to be scaled up in size, thus amplifying their sensitivity further in large-area configurations even more effectively.

Upcoming Presentation

Orbray's diamond technology will be showcased at the Japan Radiology Congress 2025, scheduled to be held in Yokohama, Japan, from April 10th to 13th. Attendees can expect to see the actual diamond radiation detectors and learn about the unique manufacturing methods that make this technology possible. Experts from Orbray will elaborate on the evaluation results, emphasizing the detector's potential to reshape diagnostics and treatment options in medicine.

Conclusion

With this cutting-edge development, Orbray Co., Ltd. stands at the forefront of radiation detection technology. The implications of their diamond detectors could significantly enhance diagnostic accuracy and treatment efficacy within healthcare, heralding a new era of precision in medical technology. As further user tests and evaluations continue, the potential applications for this revolutionary technology seem boundless.
