Samsung Develops Film-Free Flat-Panel LCD X-Ray Machine

Analog X-ray machines could be a thing of the past, thanks to Samsung's new film-free version. Measuring 45 x 46 cm, the Flat-Panel X-Ray Detector, or FPXD, boasts a 3072 x 3072 resolution, or 9.4 Megapixels. The Korean firm claims it will replace existing X-ray machines faster than digital cameras replaced film ones. Here's how it works:

First of all, photodiodes are attached to a TFT substrate produced using its proprietary amorphous silicon technology. The X-rays are detected photon by photon, before being converted into visible light, which is converted in turn to electrical signals that can be displayed as diagnostic images on a flat panel screen.

The machine also has an image enhancement function to eliminate almost all of the digital image noise interference, in order to provide the highest radiography sensitivity in the industry. The FPXD will not just be confined to medical use, as Samsung has plans to adopt the technology so that it will work with CAT scans, airport security and building inspections.

LOL @AndersonBMX:

You don't seem to understand something. X-ray equipment is NOT radioactive. There are no radioactive materials. None. Zero. Nada. To make X-rays, you need the right equipment and a power source, and even then you don't get X-rays unless you complete the circuit by pushing and holding down the exposure button.

Even "if" some dope pulled an x-ray machine from a landfill, he'd likely lack not only the technical knowhow of how to put it back together, but also the electrical source to actually power it. Think of it this way... a typical light bulb runs using 110 volts. X-ray equipment run on upwards of 110 KILOVOLTS! You aren't getting that out of a household connection. Besides, I'm quite certain that they are disassembled thoroughly enough to prevent them from being used again. The x-ray tube in particular, which can run $100,000 or so, likely will have been dissected and completely disabled. Once you've cracked the tube and lose the vacuum, it's useless. It's just like breaking a light bulb. And you can't pick up a new x-ray tube at the corner market.
