X-Ray Fans only: Latest arrivals in Fraser's lab - Large Wi-Fi X-Ray plates :)

I'd be surprised if there wasn't a layer of shielding at the back of the sensor. maybe something carefull chosen to reduce backscatter.
Micrel chip is an ethernet PHY, so there is probably ethernet on the connector.
I can't see anything that's obviously an ADC, but could be on other side of PCB

How much would you part with them for? I may be interested.

I recently tore down a large-ish digital imager, and it had a ~3mm sheet of lead directly behind the sensor. Said sensor being essentially a reversed TFT monitor, with photodiodes and read-out circuitry patterned on a sheet of glass. Which was connected to the motherboard via 60 individual FFCs...

Do be careful with the sensor, though - mine had a Cesium Iodide scintillator layer which was (supposedly, anyway) doped with a couple grams of thallium. Nasty stuff. As long as you don't break the hermetic sealing foil over it, you should be fine.

TerraHertz:
Ow. Thalium. With a couple of PM tubes with (iirc) KI-Thalium-doped scintillator blocks around here somewhere, I'd read up on Thalium risks. I'm amazed anything with Thalium in it can be marketed at all, let alone WITHOUT extreme safety warning notices all over the device.

I second the 'be careful' comment. Don't puncture the containment. Just don't.
Note the scintillator material is sealed from air because it's deliquescent - absorbs moisture from the air. Also creating a Thalium  transporting goo.

Thallium poisoning: a review.

Fraser:
Thanks for the comments guys.

It looks like the four X-Pay plates have found a new home with a well known and very clever fellow forum member. I shall not be doing a teardown on them.

Oh man, I'd love to have got my hands on one of those. I have access to an ex-veterinary 125kVp machine that something like this would be perfect for, I use film currently but it's a pain in the butt. I've been hoping to find a repairable digital plate some day, normally they are prohibitively expensive.
