MotionFree PET/CT solutions

MotionFree for Artifact Reduction

50% of PET/CT acquisitions show breathing artifacts near the diaphragm. These artifacts are due to the misalignement between the helical CT and the PET scans due to a different temporal resolution.
This is the biggest challenge in lung and liver cancer. Combining AC and NAC* PET images in this area was in the past the only remaining option to remove the uncertainty. Why would you spend time today on two images when you can get more information in a single one?
