Siemens Healthineers announces U.S. FDA clearance of the Biograph Vision.X, a PET/CT scanner with a time of flight (TOF) of 178 picoseconds. 

The scanner’s Optiso Ultra Dynamic Range (UDR) detector technology contains silicon photomultipliers (SiPMs), which enable the use of small 3.2 mm x 3.2 mm lutetium oxyorthosilicate (LSO) crystal elements. These tiny crystals provide higher spatial resolution than larger crystals. Leveraging these very small LSO crystals that are 100% covered by SiPMs, the Biograph Vision.X delivers 48-mm volumetric resolution and a temporal resolution of 178 ps.

For these reasons, the scanner can deliver a 20% performance improvement (TOF gain) that can improve patient throughput as well as reduce patient radiation exposure and radiotracer cost, according to Siemens.

“The Biograph Vision.X’s record-shattering, ultrafast time of flight delivers an image resolution that allows even the smallest lesions to rise above the noise,” says James Williams, PhD, head of Siemens Healthineers Molecular Imaging. “This extremely high level of resolution can help physicians detect small lesions and provide patients with a precise diagnosis.”

The built-in AIDAN imaging platform of the Biograph Vision.X uses artificial intelligence (AI) to increase operational efficiency and accelerate patient workflow. Its unique methodology is built on over 700 machine- and deep-learning patents from Siemens Healthineers.

Moreover, FlowMotion AI, a feature of AIDAN that is optional on the Biograph Vision.X, combines the continuous bed motion of Siemens Healthineers PET/CT scanners with anatomical AI to enable the user to standardize and personalize image acquisitions with one click.

The scanner’s large 78-cm bore helps calm anxious patients and allows easier positioning of bariatric patients or radiotherapy devices. It fits into any room that houses a PET/CT scanner from the Biograph Vision family.

The Biograph Vision.X is available as an in-field upgrade to current users of the Biograph Vision.
