Digital receivers of a series "Alpha" and "Ion" based on multitouch technology which carries out direct transformation of x-ray photons (X-ray radiation) in video a signal by means of several cameras with overlapping of fields and optical communication. The technology is patented in Ukraine, Russia, Canada and other countries.
In the optical block of the receiver the entering X-ray will be transformed by a X-ray intensifying screen to visible light which at the same time collects in video sensors. Each of sensors processes rather small field of the overview on a X-ray intensifying screen that provides high resolution of the image. The more the number of video of the sensors installed in the optical block the above spatial resolution of diagnostic images is provided with the receiver. The patented algorithm of a stitching of the image allows to carry out recovery of all image without loss of information on borders of fields. Quality of images can be improved by means of algorithms of scaling, the choice of the interesting area, setup of brightness and contrast, inversion of color, etc.
- the size of the entrance field — is not less than 380 x 380 mm;
- resolving power — not less than 4.0 pl/mm;
- threshold contrast (at a dose 0.4 mr) — no more than 2;
- dynamic range — not less than 100;
- time of obtaining the image on the monitor — no more than 10 with;
- availability of electronic archive with the database of patients is not less than 200 000 persons;
- printout of digital images on a x-ray film by means of the multiformat camera or the specialized medical DRYSTAR-5300 printer (option);
The receiver provides displays of x-ray images on the display, both in the course of registration, and after record on the magnetic or optical carrier.
