A team led by researchers from the Argonne National Laboratory used the high-intensity, quick-burst X-rays provided by the Linac Coherent Light Source (LCLS) at SLAC National Accelerator Laboratory to look at how the atoms in a molecule change when the molecule is bombarded with X-rays.
This schematic shows the dissociation of a xenon difluoride molecule during the X-ray pump/X-ray probe process.
A massive xray machine hung from the soft ceiling of the old hospital. Among the clutter of equipment we found old xray cases and drawers of records.
The Technician had a hard time getting the machine to cooperate and finally had to call someone on her cellphone to see what was going on.
This setup consists of a HD-S (high speed green) phosphor screen, and a 90kV, 15 milliamp real X-ray tube with a 1.5 amp 12 volt hot cathode.
I took the photo running the tube at 60kV and around 2 milliamps.
The exposure took 30 seconds, and the green phosphor shadow was post-processed to turn it into the more recognisable negative cyan X-ray transparency.
I use an old 20D camera because X-rays DO in fact damage CCD's as I found an increasing number of hot pixels on my new camera when I first started making X-ray images.
i wish i had a super-cool story to explain how i fractured my foot a couple of weeks ago. like "i was skiing and tumbled down the mountain." or "i went hiking and fell off the trail." maybe even "i kicked my boyfriend in the ass." nope. all i did was jump onto the sidewalk. ok, so my friends would say that i took a flying leap. maybe they're right. :-P
During test shots on my 'new' homemade 4x5 camera, with a pair of stacked close up lenses as the prime lens, I shot a pair of images one on Ortho Lith and on on Kodak xray.
They were developed in the same 1:20 paper developer and this is the result.
Each was scanned as a colour positive and the ortho was toned slightly to match the xray scan.
My dentist took xrays with this really cool USB dongle. Basically the "film" was a USB device that the computer immediately read in after the rays had been shot at my head.
Afterwards I asked if they could email them to me. Apparently that wasn't a common request.
The xray computers didn't have internet, but apparently they found some way to get it to one that did. One of the dental assistants actually had to send it to me with her hotmail account.
Some time spent photomerging... and TA-DAH! All my beautiful dental work on display.
Ok, yes it is one of my more "bizarro" photos.....
It came about because my Mum had to go for x-rays today.
So I had this "brilliant" idea to take a photo of some of her previous x-rays (she has had spinal fusion as well as a hip replacement - what you see in this pic is her replacement hip joint).
Anyways, then when I was taking the pics, I thought, "perhaps some background in these pics would look interesting".
So this is the result - the best of a "bad" bunch.....couldn't quite get the effect I was after, but still so so I think....
The background you see is basically the street scape at the front of our house - and yes, spot the car! :-)
Normal sternum with pronounced calcification of the costosternal ribs. This amount of calcification is unusual, in a 24 year old male patient. This is an example of a well visualized sternum, through conventional radiography. This particular exam is quite difficult to perform, and this level of visualization is rare.
Our xray is a digital system, made by Sedecal/VetRay. Digital is quick and provides hi quality images
Multigrade b/w paper exposed in analytical Xray box, object placed directly on the paper.
varying exposure of 25-50 kV tube voltage, from 1 to 4 minutes.
I have broken both of my ankles - twice. So I have the exact same metal plates and screws in both ankles. This is the x-ray of my right leg.
Electric conversion 1/8 scale XRay 808 buggy RC car.
Strobist info: 2xSB-28: 1st on camera right and behind camera. Both on 1/4 power and with shoot-through umbrella.
The main piece of equipment at the High-Resolution X-ray Computed Tomography Facility at the University of Texas at Austin (UTCT), where I got a custom tour a few weeks ago.
