Acquire images virtually free of respiratory motion without extending scan time1.


In 90% of the PET/CT oncology cases, disease is located in the chest or abdomen2. These areas are subject to respiratory motion, which can displace organs and lesions by a range of 5 mm to 30 mm, blurring images and reducing diagnostic confidence3.

OncoFreeze delivers images virtually free of respiratory motion without extending your scan time. It helps to improve detection, delineation and quantification of lesions and increase your clinical confidence by adapting to each individual’s unique breathing pattern to deliver the best possible image.

Key benefits of OncoFreeze

  • Provides images virtually free of respiratory motion in the same time as a regular whole-body scan
  • Helps improve delineation and quantification of small lesions, increasing physician confidence
  • Adapts to each individual’s unique breathing pattern to deliver the best possible image

General Requirements


Minimum Software Version

Biograph mCT HW/SW platform must be running PETsyngo VG70 or higher with MARS, ICS T13 and IRSmx3 hardware or higher.


PET Respiratory Gating or PET/CT Respiratory Gating option is required to enable this option.

Please Note: Additional technical pre-requisites may apply. Upon receiving your request, your local Siemens representative will clarify whether your system meets the requirements.
