The CCT189 (body)  and CCT191 (head) Low Contrast Phantoms are designed for low contrast imaging evaluations as defined by the MITA CT IQ Task Group. These phantoms replace the earlier CCT183 phantom.

Both phantoms have eight contrast rods evaluated at manufacturing to be within 0.05% density or ±0.5 HU  of target values.  The symmetric positioning of the contrast object make these phantoms ideal for conducting forced choice and rating scale experiments for evaluating reconstruction algorithms.

For further information please see the CCT189 and CCT191 MITA CT IQ Low Contrast Phantom Manual.

The CCT189 LC Body Phantom has the following contrast rods:

  • 14HU contrast, 3mm diameter x 40mm length  and 15mm diameter x 10mm length
  • 7HU contrast, 5mm diameter x 40mm length  and 15mm diameter x 10mm length
  • 5HU contrast, 7mm diameter x 40mm length  and 15mm diameter x 10mm length
  • 3HU contrast, 10mm diameter x 40mm length  and 15mm diameter x 10mm length


The CCT191 LC Body Phantom has the following contrast rods:

  • 9HU contrast, 3mm diameter x 40mm length  and 15mm diameter x 10mm length
  • 7HU contrast, 5mm diameter x 40mm length  and 15mm diameter x 10mm length
  • 5HU contrast, 7mm diameter x 40mm length  and 15mm diameter x 10mm length
  • 3HU contrast, 10mm diameter x 40mm length  and 15mm diameter x 10mm length
