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 />

Background information<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 />

CIREA AB<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 />
