At the 30th Annual Congress of the European Association of Nuclear Medicine (EANM), Oct. 21-25 at the Austria Center Vienna, Siemens Healthineers debuts the Biograph Vision1, a positron emission tomography/computed tomography system designed to deliver a new level of precision in PET/CT imaging. Also at EANM 2017, Siemens Healthineers unveils new software features designed to bring advanced clinical capabilities to the Biograph Vision as well as the company’s established Biograph mCT and Biograph mCT Flow PET/CT systems.
The Biograph Vision PET/CT system features new Optiso Ultra Dynamic Range (UDR) Detector Technology, which is based on silicon photomultipliers (SiPMs) rather than the photomultiplier tubes (PMTs) that have been the industry standard. This new system design enables Siemens Healthineers to reduce the size of 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, which may improve lesion detectability. Utilizing these extremely small LSO crystals and covering 100 percent of the area of the scintillator array with SiPMs², the Biograph Vision is designed to deliver the industry’s fastest time-of-flight (TOF)³, with a temporal resolution of just 249 picoseconds².
The new software platform from Siemens Healthineers contains four optional features that are designed to provide optimal performance to the new Biograph Vision PET/CT system. These software features also will be available as options on the company’s established Biograph mCT family of PET/CT systems.
The QualityGuard feature¹ is designed to self-calibrate the PET detector by tapping natural background radiation from the LSO detectors to run daily and weekly quality control (QC) procedures during off-hours².
A second software feature, FlowMotion Multiparametric Suite,¹ is a fully automated solution designed to deliver whole-body PET images of tracer uptake rate and distribution volume, in addition to the standard static PET images.
The OncoFreeze¹ feature is designed to provide images that are virtually free of respiratory motion and finally CardioFreeze¹ addresses issues associated with cardiac PET/CT image acquisitions. The software is designed to correct for respiratory and cardiac motion.
¹ Biograph Vision, OncoFreeze, CardioFreeze, QualityGuard, and FlowMotion Multiparametric Suite are currently under development and do not yet fulfill all the essential requirements according to the European Medical Device Directive (93/42/EEC) and its national implementations. They are not yet commercially available in the European Union nor available for sale in the U.S. or any other country. Future availability cannot be guaranteed.
