Rayence unveils the first X-ray detector technology utilizing SPAD technology

South Korea: South Korean company, Rayence, has successfully applied ‘SPAD-GS’ technology to 3D detectors, presenting its cutting-edge detector technology at the International Solid-State Circuits Conference (ISSCC) 2023.

The technology is touted as the world’s first X-ray detector to utilize ‘SPAD’ digital pixel technology capable of single-photon detection.

Next-Generation 3D Detector Technology

The SPAD-GS technology is the next-generation 3D detector technology that provides optimal image quality even in low-dose/high-speed driven environments.

The ‘SPAD’ device amplifies photons to recognize very small levels of photons as if many photons have entered. By applying ‘SPAD’ digital pixels to detectors, X-ray images can be acquired even in extreme low-dose environments, and the detection speed is significantly increased.

Rayence is the first to successfully introduce ‘SPAD’ digital pixels to X-ray detectors.

GS Technology Eliminates Motion Blur

Rayence has applied GS technology, which captures high-quality images by eliminating motion blur when the object moves quickly. Rayence has minimized the degradation of image quality caused by object motion by combining ‘GS’ technology with the fast response speed of ‘SPAD’.

Rayence’s technological capabilities have enabled the company to overcome major obstacles to the application of ‘SPAD-GS’ technology, such as low robustness, high power consumption, and image distortion.

Designed for Ultra-Fast 3D Images

The ‘SPAD-GS’ technology is expected to attract attention in fields where X-ray imaging results need to be utilized as ultra-fast 3D images.

The primary application of this technology will be in medical devices such as C-arms, which require real-time X-ray imaging during orthopedic surgery.

In addition, the technology could also be implemented in the battery and electronic component testing as well as aerospace and nuclear component inspection markets, where inspection time for images can impact production costs.

Rayence plans to begin mass-production within several years after completing clinical trials and obtaining certifications.

Rayence has built a complete lineup of manufacturing facilities and supplies X-ray detectors and I/O sensors (intraoral sensors for dental imaging) to various industrial fields as well as the entire medical industry.
