The Biograph Vision.X is a positron emission tomography/computed tomography (PET/CT) scanner with a time of flight (TOF) of 178 picoseconds (ps). 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-mm volumetric resolution and an industry-best 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. 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.
