The new effective detector for digital scanning radiography

Abstract The new effective one-dimensional detector for digital scanning radiography is presented. The progress in the design of low-noise electronics allowed the Multistrip Ionization Chamber to be used as the X-ray detector. The detector has been designed for use in the Low-dose Digital Radiographic Device “Siberia” instead of a multiwire proportional chamber. The working gas is Xe under 12 atm pressure. The main detector parameters are as follows: total number of channels, −1024; channel size, −0.4×0.4 mm 2 ; space resolution, −1.25 lp/mm; contrast sensitivity, −1%; dynamic range, −480; surface dose for chest image, −3 to 5 mR.
