Vision<br />
The new sensor concept is applied in the three key application areas:<br />
Combined current mode / spectral photon counting CT.<br />
Here only detector heads and software need be replaced in current CT systems –<br />
the shortest path to clinical use of the technology.<br />
Integrated PET/CT<br />
Combined therapeutic/diagnostic imaging system for cancer therapy, largely<br />
based on PET/CT.<br />
Wide range sensor for combined medical imaging systems<br />

Wide range sensor for combined medical imaging systems<br />
Commercial implementation routes<br />
We develop detector modules for key applications, in collaboration with systems<br />
manufacturer.<br />
We license/ sell IP to systems / component manufacturer, in combination with the<br />
above.<br />

Detection efficiency, currently ~25%-40%<br />
Sensitive to single photons (high intrinsic gain ~10 5 -10 7 )<br />
Can measure pulsed/continuous photon fluxes due to many active<br />
elements (~ 100 – 20000 pixels)<br />
- emulates function of classic PM tubes<br />
Operational characteristics:<br />
– Needs low bias voltage ~20-80 V,<br />
– Works at room temperature<br />
– Insensitive to magnetic fields (compatible with MR)<br />
– Requires a minimum of electronics<br />
– Dark rate ~ 100 – 500 kHz (single pixels firing)<br />
Miniatyrized and possible to pack in matrices.<br />
Low cost (estimated < $10/pce for mass production)<br />
Recently in production at Pulsar, Hamamatsu Photonics, SensL and others<br />
