A radiograph of my new Pixel 6 phone. The Pixel 6 is a big chunky phone with a lot of stuff in it.
This one was acquired using a portable x-ray unit at 80 kV, 1 mAs, and the small focal spot. It’s raised up about 25 cm above the image receptor for a bit of magnification (about 1.3x) and cropped in from the original image.
Radiograph of my Galaxy S7. 80 kVp, 2.8 mAs, Canon Aero DR detector.
The large rectangular gray block is the battery. Superimposed on the battery, the NFC and wireless charging coils are easily seen. Volume buttons are on the upper left side, and the power button is on the right side. The rear camera is the square object in the upper middle. The selfie camera is the white donut shaped object just above and to the right of the rear camera. There’s the micro-USB port at the bottom middle, and the headphone jack to the left of the USB port.
Today, I was doing some testing on a mammography unit and acquired another x-ray of my Nexus 5. The mammography unit uses a much smaller focal spot, and will produce much sharper images. However, with the much lower kV mammography units use, it’s a lot harder to get adequate penetration through denser objects (like circuit boards and batteries).
This image was acquired at 34 kV and 120 mAs using the large (0.3 mm) focal spot. Its pretty easy to see that this one is a lot sharper than the other image (click the image to embiggen to all it’s glory).
The main circuit board area towards the top as well as the battery is harder to see through than the other version, because of the lack of penetration of the low energy x-rays. It’s a lot easier to see some of the detail in the circuit board at the bottom of the phone, because there’s less to go through there.
Continuing the tradition of making radiographs of my electronic things, I got a radiograph of my new Nexus 5, the DDS modules and the Arduino Pro Mini.
The Nexus 5. The battery takes up a good bit of the space inside. The square object to the right of center near the top is the camera module. The SIM card tray is easily visible below that. The boards look pretty crowded (click for the jumbo sized image).
The AD9850 modules. Not a whole lot to them. The crystal in each module is easily visible as the rectangular object on the left. The AD9850 chip is in the middle.
Sparkfun Arduino Pro Mini. Not a whole lot to this either. There’s the AT Mega 328P chip in the middle, and at the top is the reset button.
All images were acquired using an 8″x10″ cassette. X-ray technique was 80 kVp, 5 mAs with the small focal spot (0.6 mm). Source to image distance (SID) was 172 cm, and the object to image distance (OID) was about 100 cm giving a magnification factor of about 1.7. This results in some magnification blur, but at this magnification, the Nexus 5 takes up pretty much all of the cassette.
