Standard detectors for value and mainstream medical CT imaging

The X-ACE is the industry’s first standard detector series optimized for value and mainstream medical CT imaging needs. The plug-and-play-type solution is available as 16-slice and 32-slice detector cards, and alternatively as a complete subsystem that includes the X-ACE 16 or X-ACE 32 detector modules, X-DCB2 data combiner board, software libraries, and all the necessary accessories. The investment-free series brings notable total cost savings and speeds up the time-to-market of advanced CT systems in the highly competitive medical imaging segments.

The X-ACE product family is built on the well-proven and modular platform. The platform covers a wide imaging area and features the highest level of integration, as a scintillator, a photodiode, analog-to-digital converters (ADC), and a field-programmable gate array (FPGA) are assembled to a single printed circuit board (PCB). As a benefit, this means simplified system designs, straightforward integration, minimized risks, a streamlined supply chain, and detector solutions that are mechanically more robust and digitally enhanced.

The platform easily scales up from 16-slice to 32-slice system configurations to cover a wide range of set-ups, and enables 20-millimeter coverage at the isocenter. The X-ACE 16 is a 16-slice detector for 20-mm anatomical coverage, whereas the X-ACE 32 provides high-resolution, true 32-slice imaging with the same coverage.

The X-ACE series provides high image quality with low doses at fast scanning speeds for enhanced patient safety and experience. State-of-the-art performance is enabled by a pixelated, ultra-fast ceramic scintillator, coupled with a high performance frontside-illuminated (FSI) photodiode. The scintillator is made of high-light-output and medical grade GOS (Gadolinium Oxysulfide) compound. The characteristics of the most sensitive and ultra-low dark current photodiode are enabled by utilizing a unique FSI photodiode manufacturing process.

The detectors come with a 24-bit ADC providing fast, low noise, and high-resolution analog-to-digital conversion. Furthermore, the detector modules feature an adjustable fullscale range. The solution is compatible with an X-Link digital LVDS (low-voltage differential signaling) interface. For speeding up design and system integration, world-class engineering support and a customer evaluation unit are available.
