The new Siemens Healthineers system offers 20% performance improvement boost throughput

Siemens Healthineers has announced the U.S Food and Drug Administration (FDA) clearance of the Biograph Vision.X, a positron emission tomography/computed tomography (PET/CT) scanner which it reports has an industry-record time of flight (TOF) of 178 picoseconds (ps).


November 22, 2023 — Siemens Healthineers has announced the U.S. Food and Drug Administration (FDA) clearance of the Biograph Vision.X¹, a positron emission tomography/computed tomography (PET/CT) scanner with a time of flight (TOF) of 178 picoseconds (ps)—the industry’s fastest TOF.² The next-generation system builds on the established performance of the Biograph Vision family of scanners.

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 percent covered by SiPMs, the Biograph Vision.X delivers high 48-mm³ volumetric resolution and an industry-best temporal resolution of 178 ps. For these reasons, the scanner can deliver a 20% performance improvement (TOF gain)³ that can improve patient throughput as well as reduce patient radiation exposure and radiotracer cost.

“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,” said 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 intelligent 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, which pioneered AI-powered applications in PET/CT scanners. FlowMotion AI, a hallmark 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.
