Tittle:
True color X-ray imaging by dual-energy photon counting using standard contact image sensors
Summary:
A Flemish SME developed a true color X-ray photon counting technology aimed at the highest possible scalability and manufacturability at an economic level.
They want to cooperate (mainly) with industrial partners via license agreement, technical or commercial agreement, and are also interested in further development.
Description:
With extensive usage of radiography in medical diagnostics, achieving the lowest possible dose imaging is a driving force for the X-ray image sensor community. Furthermore, medical diagnostics would benefit greatly from true color X-ray imaging.
A low-cost and low-power X-ray photon counting detector has been developed with the highest possible scalability and manufacturability. The sensor allows direct coupling with scintillators. It discriminates between two X-ray energy levels, allowing true color interpretation of the data.
Standard CMOS (Complementary metal-oxide-semiconductor) and CIS (contact image sensor) technology are being used, which resulted in a USB camera demonstrator (92x90 pixels @ 1cm²) for true color X-ray imaging. This demonstrator can be easily expanded till a wafer level device (e.g. 14x14cm2 area).
Beyond space and medical application, this technology could be usable in other X-ray applications such as non-destructive testing, µCT(computer tomography), healthcare, luggage inspections, etc. as it allows (proven) better interpretation of the images.
The technology accurately counts X-ray photons and differentiates between their energy, thus deriving properties of the material where the X-ray went through. For medical applications : by determination of the energy and amount of X-ray photons, tissue types can be discriminated with a proven higher success rate and visualized more clearly e.g. the difference between Fat (Carbon rich) and blood (Oxygen rich) areas.
The proposed photon counting technology makes use of standard contact image sensors (CIS) technology and works with off-the-shelf scintillators. Due to the straightforwardness of CMOS chip design, the innovation will allow real-time evaluation on site on various equipment. It is portable to any foundry where a pinned diode module is available. The sensor architecture is designed to maximize yield of wafer-scale devices.
Beyond a multitude of medical application and proven benefits to medical diagnostics, this technology is also usable as such in other X-ray applications, for instance non-destructive testing (µCT), dentistry, luggage inspections, etc.
The technology provider is a design house from Belgium for turn-key, high-end, high performance image sensors for space, medical and other application domains.
Advantages and Innovations:
The dual channel photon counting with scintillators incorporates the following concepts:
· High scalability, by stitching and minimal gab abutting
· High manufacturability (wafer scale devices of 14x14cm2)
· No heavy semiconductor hybridization, but rather using optically coupled scintillators (more economical)
· Use of 0.18µm standard CMOS Contact Image Sensor technology
· Front side illumination
· High yield is ensured by a low transistor count per pixel and fault tolerant design
· Low power consumption due to the CMOS technology
· Real-time evaluation on site on various equipment is possible
