Siemens Healthineers Biograph Vision PET/CT System

The Biograph Vision features new Optiso Ultra Dynamic Range (UDR) Detector Technology, which is based on silicon photomultipliers (SiPMs) rather than photomultiplier tubes (PMTs). This design enables Siemens Healthineers to reduce the detector’s lutetium oxyorthosilicate (LSO) crystal elements from 4 x 4 mm to 3.2 x 3.2 mm, resulting in higher spatial resolution. Utilizing these extremely small LSO crystals and covering 100 percent of the area of the scintillator array with SiPMs, the Biograph Vision is designed to deliver a fast time-of-flight (ToF), with a temporal resolution of just 249 picoseconds, as well as highly effective sensitivity at 84 cps/kBq. The Biograph Vision helps to reduce scan time by a factor of 3.9 to improve patient throughput as well as reduce patient radiation exposure and tracer cost. It has a large 78-cm bore that offers 24 percent more space than a 70-cm bore. The system fits into any room that houses a PET/CT scanner from the Biograph mCT family without the need for costly renovations.
