Whole-body tomography PET/CT scanner uMI Vista

for brain tomographyfor cardiovascular tomography160-slice

Overview
uMI Vista integrates Integrated‑Light‑Guide Digital PET technology with a 160‑slice CT system to deliver co‑registered functional and high‑resolution anatomical images for clinical workflows in oncology, neurology and cardiology. Advanced reconstruction and modular system design support precise lesion detection and quantitative imaging.

Key technologies & components

• SiPM based Integrated‑Light‑Guide Digital PET Detector
• Integrated‑Light‑Guide: improves light collection efficiency and spatial resolution
• SiPM technology: increases photoelectric conversion efficiency to reduce signal loss and yield outstanding image quality
• High‑precision ultra‑fine crystals: significantly enhance image resolution
• Modular design: high‑level modularity for system reliability and serviceability
• Clear imaging chain from detection to reconstruction
• Comprehensive PET and CT application support

Performance & Imaging Features

• 2.9 mm NEMA resolution achieved through systematic imaging chain engineering
• HYPER Iterative Reconstruction: improves signal-to-noise ratio (SNR) and contrast recovery to aid lesion detectability and quantitative accuracy
• 24 cm large axial field of view (Axial FOV)
• 4 bed positions for a whole‑body scan to expand clinical efficiency
• High speed scanning: example whole‑body scan in ~8 minutes to increase patient throughput
• Clinical capability examples: 40.3 BMI patient imaging, 0.05 mCi/kg FDG imaging, detection of 2.2 mm small lesions, high‑resolution brain imaging, gastric lymphoma with FDG

160‑slice High‑performance CT highlights

• 0.3 s rotation speed for high temporal resolution CT imaging
• 70 kV scan mode for lower CT radiation dose and improved image contrast
• 0.5 mm acquisition element delivering high SNR and image quality
• 1024 x 1024 reconstruction matrix for high spatial resolution to visualize fine anatomical details
