Performance evaluation of a mosaic detector in digital radiography

• Simulation code EGS4

• Experimental set-up

• Irradiated area 18x18 cm2

• Fluence at the phantom surface 0.23x106 g/mm2

• Limits

  • Computing time

• Studies:

  • comparison between a full field detector and a mosaic detector
  • geometry optimization for rejection of Compton background
