Cone beam reconstruction techniques

• GE

  • MDMP algorithm (development of ASSR)
  • Non uniform data weighting gives more weight to central detectors

• Siemens

  • AMPR algorithm (development of ASSR)

• Toshiba

  • TCOT, Coneview (Feldkamp based)

• Philips

  • ‘Cobra’ (Feldkamp based ‘n-?’ reconstruction)

• In general some redundant data with cone beam reconstruction techniques, so noise may be expected to increase
