Aurora CT

Aurora CT is the industry’s first off-the-self detector subsystem for security CT applications. The plug-and-play-type solution includes ready-made, multislice detector boards, a control unit and a software library. Aurora CT speeds up time-to-market and decreases total costs of X-ray imaging systems that meet the most stringent security equipment standards in aviation.

Aurora CT is built on the well-proven, modular, and easily scalable Aurora platform that is powered by a 20-bit, application-optimized single-chip ASIC. With the highest level of integration and a simplified system design, Aurora CT provides superior image quality, features robust structure and reliable mechanical and electrical interfaces, minimizes risks, and streamlines supply chains.

The 3-sided tileable detector modules easily scale from 16-slice up to 64-slice system configurations to cover a wide range of set-ups, from entry-level checkpoint carry-on baggage scanners to large hold baggage CT scanners. The modules are available in flexible single-energy constructions, which also support dual-energy configurations. Aurora CT withstands G-forces of rotating CT systems up to 20 G, and its design ensures very high radiation hardness for long product lifetime.

Aurora CT comes with sparse and full pixel matrix options. The detector matrix is built on individual low-noise BSI (backside-illuminated) photodiodes for ultra-low crosstalk and low noise to meet high spatial resolution and penetration performance requirements. The scintillator matrix has high light output, and is practically afterglow-free to ensure high image quality without artifacts at fast scanning speeds.

The subsystem includes X-DCB (data combiner board) as an essential part of the DAS. Precise synchronization with a rotating gantry can be implemented with flexible encoder interface. Aurora CT has an optical, high-speed datalink from the DAS to a host computer. This is a proven solution for system integration with the data transmission over rotating slip ring. Aurora CT detectors and X-DCB support remote firmware updates for smooth system development and possible adaptation to new requirements. Various development and diagnostics functions are included to confirm the status, and monitor the health of the system. In addition, software library is available to support rapid integration of the inspection system.
