Airport security style X-ray image of a Mosque alarm clock created by taking pictures of each individual part and re-assembling it in photoshop.
This particular clock required about 30 images to produce.
Thanks to Johannes Henseler for creating this great tutorial on how to do this.
A half shoulder of lamb, X-Rayed with my heavily modified Scanmax 20.
My X-Ray machine started life as a mailroom scanner in a bank. It's about the size of a filing cabinet. When I got it the resolution was pretty poor - it used a standard video camera to make the images. So I tinkered with it (making sure I didn't affect anything that was involved with safety of course). I replaced the original high brightness, low definition phosphor with a Kodak Lanex Fine screen (less sensitive but much higher resolution), then replaced the video imaging system. First, I used a Nikon D3100 I had floating around, remote controlled via DigiCamControl. More recently, as noted above, I've upgraded to a Nikon D700 that became spare. DigiCamControl is what makes it possible for me to remote-control the camera safely and get images directly into the computer via USB.
Please, please, please don't think that you can just get an X-Ray machine off eBay or wherever and safely start making images like this. Without proper shielding and other precautions, ionizing radiation such as X-Rays can be seriously hazardous to your health.
An old X-ray of my hip. This shot is nearly 3 years old now, but my newest x-rays are nearly identical. The odd looking spot in the neck of the femur is a benign bone cyst. I had the cyst removed the first time in Aug 2004, then procedded to fall down 1 stair (not a flight, just 1 stair) and broke the hip. The pins are highlighted in bright white- there used to be one more of the long pins, but it was removed. Still left is 1 more long pin, a support plate, and 3 screws.
The remaining cyst, which was leftover from when I broke the bone (graft liquid can only stay in there as long as the bone is whole, so no more healing once it broke), started to get bigger again about 3 years after my first surgery. We did a second chemical bone graft at the time. The graft was starting to set at the time this particular x-ray was taken, which you can see in the milky white area towards the left side of the remaining cyst.
It has been over 40 months since the last graft and the doc has told me to expect it to take another 3-5 years to finish healing, simply because bone heals horribly slow for me. BUT, I should be safe from surgery for at least 15-20 more years.
Me playing with my friend's mac. he has this photobooth program which I was just playing around with...
I figured I'd take a picture with the xray option of my teeth.. Its one of my best features.. lol.. (my patient says so)
My arm as it was on 2010-07-21 about halft an hour after the accident. The lines on the right were from the rig that was used by SAMU to immobilize my arm.
all done now, this is what i call quality work ;-) now i can operate it downwards too.
means i can just put things on the film instead of fixing them with tape and setting up the film vertically.
im also going to build a nice wooden stand for it.
Photographic film is sensitive to X-rays, but few rays interact with it. (X-rays passing through matter is a blessing and curse)
To speed up the exposure, the photographic film is placed between two plastic screens of phosphor that glow when X-rays hit them. These are glued to the two inside sides of the X-ray plates. In the photo above, one screen remains, and one has been removed from the opposite side of the left plate. The right plate is closed.
This extra green light from both sides further exposes the X-ray plate - making a faster exposure.
The plates can be photographed using a long exposure in complete darkness when exposed to X-rays to get a bright green silhouette of an object between the X-ray source and the phosphor screen.
The plates are coated with various forms of phosphor that most often glow blue or green - and come in several sensitivities. The more sensitive the phosphor, the brighter it glows, but the blurrier the image it produces due to the crystal size.
For my images I use a HD-S screen which is a bit faster than normal and still gives fairly sharp results.
In modern X-ray units none of this hardware exists - a re-useable electronic X-ray sensitive plate is used instead. =(
