A low-dose x-ray imaging device

We describe a digital x-ray imaging device with a one-dimensional multiwire proportional chamber used as the detector. The device works in direct counting mode. In combination with high quantum efficiency, zero intrinsic background and pixel size of 0.6 mm it allows significantly lower irradiation d...

Summary:We describe a digital x-ray imaging device with a one-dimensional multiwire proportional chamber used as the detector. The device works in direct counting mode. In combination with high quantum efficiency, zero intrinsic background and pixel size of 0.6 mm it allows significantly lower irradiation doses and improved image quality for some types of radiographic study. At present the device is officially certificated for medical use in Russia. It is produced industrially in Russia, and several tens of such installations are already operating in hospitals.
