The Optima CT660 FREEdom Edition is designed to help you address challenging imaging situations, offering both high image quality and multiple dose reduction features on one platform - helping your clinical practice deliver performance without compromise.

The system also features SnapShot Freeze, an intelligent motion correction breakthrough that significantly reduces coronary motion, transcending the limits of CT rotation speed.


Tried and True Technologies

  • SnapShot* Freeze delivers equivalent gantry rotation of 0.058msec and effective temporal resolution of 29sec.
  • SnapShot* Pulse imaging combined with ASiR* may enable a dose reduction of greater than 83% compared to gated helical acquisition.
  • Innovative 40-mm V-Res detector at 0.35-sec rotation speed.
  • Up to 60% lower CO2 emissions using the energy saving mode.
  • ASiR1 technology may allow for lower mA exams throughout the body.
  • Simplified workflow for quick and streamlined operation.
  • Scalable, modular design for ease of service.
  • Volara digital data acquisition system produces up to 128-slice axial reconstruction for improved Z-axis visualization and artifact reduction.

1. In clinical practice, the use of ASiR may reduce CT patient dose depending on the clinical task, patient size, anatomical location, and clinical practice. A consultation with a radiologist and a physicist should be made to determine the appropriate dose to obtain diagnostic image quality for the particular clinical task.
