Abstract:
The EOS X-ray imaging system is a low-dose, 3D imaging system manufactured by EOS imaging (formerly known as Biospace Med, Paris, France). The imaging system relies on the high sensitivity of a special detector (a multi-wire chamber invented by Georges Charpak, for which he was awarded the 1992 Nobel Prize) to produce high-quality images with less irradiation than standard imaging techniques. Thus, EOS delivers a radiation dose that is 6 to 9 times less than a standard X-ray film and 20 times less than a basic computed tomography scan. The technique allows capturing simultaneous frontal and lateral head-to-toe images of patients in the upright, weight-bearing position with an outstanding image quality. True to size images (1:1 scale) for surgical planning and monitoring of bone and joint diseases can be also obtained.
