Biograph Vision is the next-generation of PET/CT scanners that empower you to see a whole new world of precision with AI and more.  It goes beyond digital to reveal the bigger picture and combines our patented ALPHA technology to maximize efficiency and help you to better understand disease progression.

Features & Benefits

Artificial intelligence to improve patient experience

AIDAN: Artificial Intelligence for PET/CT

Now with AI implementation at the scanner, our intelligent PET/CTs can easily and efficiently perform PET/CT exams. AIDAN scanners are designed to expand precision medicine and improve the patient’s experience.

Our AIDAN systems provide:

  • Cybersecurity
  • Clinically-driven innovation
  • Patient-focused design
  • Artificial intelligence

Accuracy to reveal the bigger picture

Biograph Vision is specifically designed to break through the limits of spatial and temporal resolution. With 3.2-mm crystals, Biograph Vision delivers high spatial resolution to reduce the impact of partial volume effect (PVE). Along with higher spatial resolution, a faster time of-flight also makes it easier to see small lesions2. This helps you quantify more accurately and more confidently understand disease progression.

Professor Ronald Boellard
“…by improving the spatial resolution…you have less partial volume effect, so you get sharper images and more accurate quantification.” Professor Ronald Boellard, PhD University Medical Center Groningen, Groningen, The Netherlands

Performance to maximize efficiency

Biograph Vision can help you optimize your clinical operations with quality images and efficient workflow. With the market’s highest effective sensitivity at 100 cps/kBq3 and the fastest time-of flight in the industry4 Biograph Vision can not only reduce scan time and injected dose to boost productivity, it can also improve image quality. Combined with FlowMotion, it is designed to reduce unnecessary exposure to CT radiation, provide greater patient comfort, and decrease examination times.2

Professor John Prior, PhD, MD
“We have now already, as compared to the older system, reduced the activity we inject… Now it's probably 30% faster with about 30% less dose which is something very acceptable.” 2 Professor John Prior, PhD, MD, FEBNM Centre Hospitalier Universitaire Vaudois (CHUV), Lausanne, Switzerland

Reproducibility to understand disease progression

Biograph Vision can help reduce unwarranted variations to maximize patient care. Its zero-differential-deflection patient bed provides perfect registration between the CT and PET fields of view, ensuring accurate attenuation correction for more precise quantification. QualityGuard5 automates daily and weekly quality control without a radioactive source to help produce consistent and accurate results. FlowMotion Multiparametric PET Suite makes it easier and faster to perform parametric imaging in daily clinical routine. It is completely automated and integrated into the PET/CT workflow for more reproducible images.

Richard E. Carson, PhD
“Being more quantitative, our reproducibility can be that much better, and it may matter when we’re trying to do a repeat scan early on in a therapy and decide what to do.” Richard E. Carson, PhD Yale PET Center Yale School of Medicine, New Haven, CT, USA
