I was doing some testing on a radiographic room today and took the opportunity to get a better x-ray image of my Galaxy S II. This was acquired using 80 kV, 5 mAs with a little bit of magnification.
Compared to the previous x-ray I took, the NFC antenna integrated into the battery looks like it’s probably the series of concentric traces, like those RFID security tags you find in books and stuff. The components on the circuit boards are also much more visible in this one.
Galaxy S II X-ray
A new Orthoscan mini C-arm arrived at the hospital last week, so while I was doing the acceptance testing on it today I used it to get a shot of my Galaxy S II.
The big grey blob in the middle is the battery and the vertical stripe in the battery I’m guessing is the NFC antenna. The square just below the top would be the camera. The square to the left of that just below the top is the front facing camera. On the right side is the headphone jack. The rectangular thing at the bottom to the right of the USB/HDMI connector is the speaker I think.
