OncoFreeze™1 AI addresses today’s respiratory motion management challenges. Building on the benefits of OncoFreeze technology, OncoFreeze AI integrates Siemens Healthineers’ proprietary deviceless waveform and anatomical algorithm technology to enable a motion management solution with a simple click of a button.
Breathe easy with OncoFreeze AI: simple, one-button, deviceless correction that reduces scan time2 and setup while enhancing patient comfort.
With OncoFreeze AI, you combine the power of deviceless waveform generation and Automated Landmarking and Parsing of Human Anatomy (ALPHA) technology to seamlessly create images virtually free of respiratory motion in the same amount of time as a conventional whole-body scan.
“Now, with OncoFreeze AI, we can offer better-quality scans, independent of indications.”
ALPHA technology
ALPHA technology is a unique, deep learning, artificial intelligence algorithm that detects specific anatomical landmarks. This allows for automatic identification of the zone to be corrected for respiratory motion.
OncoFreeze AI eliminates the need for additional setup of external physiological devices both on the patient and at the scanner and acquires a respiratory waveform that will be used to generate motion-frozen or cine, PET reconstructed images.
Our deviceless waveform is a respiratory signal derived directly from the acquired raw PET list-mode data. The deviceless waveform leverages FlowMotion™ (continuous bed motion) to always know its location over the body and determine the respiratory signal for axially extended PET acquisitions.
Using a deviceless waveform can have an additional benefit because it can acquire a respiratory waveform even in the case where an external device would fail.
“Using OncoFreeze AI is so much more comfortable for the patients and has an impact— especially for claustrophobic and nervous patients.”

Optimal flow algorithm: OncoFreeze uses the optimal gate image as a reference and employs an optimal flow algorithm to deblur the static image to match the optimal gate image, using 100% of the information.
