Digital X-ray: from alpha to gamma
For a long time itched my hands to write something good and eternal about digital radiography, which I have been doing for 5 years already. About myself - 12 years in the development of iron. I started as a designer, then there was circuit design, development of printed circuit boards, documentation development, work with CNC, HW /SW integration, project management, marketing. In general - with the world on a string.
We are engaged in the development and production in Russia of digital flat panel X-ray detectors for industry and medicine. If anyone forgot what an X-ray is - see "Experience in fluoroscopy at home" , "Homemade X-ray computer tomograph" , but do not forget about the harm of ionizing radiation during home experiments.
For whom all this is needed?
First and foremost for the medical profession, this is the largest market. Film X-ray is outliving its century, in large cities everywhere there is a figure.
In the second - power structures and security guards. In scanning scanners, a detector is used in the form of a narrow ruler, but when it is necessary to obtain high image quality, for example, when banned in unexpected places of the human body or searching for bookmarks /bugs in equipment, a flat panel detector is used.
In the third - to production workers. This quality control of welding, casting, soldering of metals and mounting of electronic components. If the welding and casting are still sitting tightly on the analogue, since the standard for the use of the digital X-ray came out in the Russian Federation only in 201? serious operators of the lines for installing the boards have for their hearts the X-ray control as a minimum of BGA chips.
"X-Ray Detector Characterization - a comparison of scintillators" . Roughly - up to an energy of 60 kV use GadOx, above 100 - CsI, in the middle both options. For reference: mammography is a range from 20 to 40 kV, conventional medicine from 50 to 150 kV, industry from 150 to 450 kV.
Yes, I completely forgot, to collect all this goods into a single unit is simply not possible, we need a clean room and equipment for combining the sensors with the maximum accuracy, we can get 1 pixel.
As a data transfer protocol, is often used. GigE Vision /Genicam , since Gigabit Ethernet is the physical layer. With a large matrix size and dynamic mode of operation it is not enough, we have to use Full CameraLink or fiber.
As a result, the detectors look like this:
You can remove welding, ceramics, metal-powder printing, boards with BGA chips, laboratory animals and tomography of small objects. If anyone is interested and there are fresh ideas for use - write, we will be happy.
