One image.
All the counts.
Motion eliminated.

The goal: the clearest, most accurate image possible.

Q.Freeze combines the quantitative benefits of 4D phase-matched PET/CT imaging into a single static image.  By collecting CT and PET data at each phase of the breathing cycle, then matching the data for attenuation consistency.  None of the acquisition data is wasted, as 100% of the counts collected are combined to create a single static image.  The goal – a resulting image that has the dual benefit of frozen patient motion and reduced image noise.
