Siemens debuts sensitive extended field of view scanner designed for clinical and research use

During the virtual annual congress of the European Association of Nuclear Medicine in October Siemens Healthineers introduced the Biograph Vision Quadra, a CE-marked PETCT system designed for clinical use as well as translational research.

In addition to the 3.2mm silicon photomultiplier (SiPM) detector technology and time of flight performance that are cornerstones of the established Biograph Vision PETCT, the Biograph Vision Quadra has an extended 106cm axial field of view (FoV) – four times the PET axial FoV of the Biograph Vision 600. “These features deliver significantly increased effective sensitivity and enable the clinician to image the average patient dynamically from the top of the head to the thigh in just one position,” states Siemens. With the scanner’s extended axial FoV, the clinician can examine patient anatomy during radiopharmaceutical uptake over time.

The combination of SiPM detectors and extended axial FoV permits more anatomical coverage in one bed position than a standard PETCT system, enabling fast scanning at low patient radiation dose.

“The Biograph Vision Quadra is an order of magnitude more powerful than current state-of-the-art clinical scanners available today,” said Siemens Healthineers GB&I molecular imaging business manager Lawrence Foulsham. “This scanner will open possibilities for the imaging of complex and subtle biological processes that are key to the understanding of physiology and pathophysiology alike.”
