The Sensor Makes the Difference<br />
CdTe-CMOS X-ray Imaging<br />
As a developer we are renowned for innovation.<br />
As a manufacturer our watchword is quality.<br />
As a business partner we guarantee commitment.
CEOs message:<br />
Ajat is dedicated to research, development and in-house production of<br />
advanced radiological digital imaging sensors. Through consistent and<br />
focused research and development we pioneer CdTe based high definition<br />
digital imaging sensors. Since the early days, we have placed in the market<br />
more than 1,000 sensors and have generated some breakthrough products<br />
including CdTe sensors operating in charge integration, TDI or energy<br />
dispersive photon counting mode with small pixel size.<br />
Our sensors serve the <strong>dental</strong> (2D, 3D imaging), medical<br />
and industrial sectors. We are inclined towards<br />
our customer’s needs and customization to specific<br />
requirements of even challenging applications.<br />
Ajat thrives to continuously improve the quality of<br />
its imaging products, increase functionality and reduce<br />
the cost of manufacturing by introducing smart<br />
processes, automation and create a new paradigm<br />
of affordable high quality.<br />
Our strategy is based on expert human resources,<br />
know-how, in-house manufacturing and patented<br />
technology.<br />
We value our customers and we try to react always<br />
with enthusiasm, professionalism and respect<br />
towards their needs. Finally, we believe in relationships<br />
and see that advanced technologies, such as<br />
the CdTe-CMOS or CdZnTe-CMOS, reach the market<br />
and society most effectively through partnerships.<br />

Innovative CdTe Sensor Technology<br />
Direct Conversion<br />
X-ray absorption efficiency (typical material thicknesses)<br />
Innovative CdTe sensor technology converts X-rays<br />
directly to electronic signals. Since X-rays are not<br />
converted into light, less blurring occurs and picture<br />
clarity and contrast are greatly enhanced.<br />
