Whole-body tomography PET/CT scanner uMI Panvivo

for brain tomography80-slice160-slice

Overview
uMI Panvivo is a high-performance PET/CT platform built on the uExcel platform that advances diagnostic precision with top-tier NEMA spatial resolution and leading TOF timing resolution. The platform emphasizes accessibility with an air-cooled, compact design, human-centric features, and a fully AI-empowered workflow to deliver consistent clinical and research performance.

Key platform features

• Scalable, modular detector and extendable architecture enabling flexible axial field-of-view (AFOV) options (24 cm, 30 cm, 53 cm, 71 cm, 107 cm) to meet clinical demands.
• On-site upgradability in existing spaces to expand coverage and capability.
• Air-cooled system: no equipment room or water chiller required.
• Fully AI-empowered workflow and post-processing for streamlined procedures and improved diagnostic confidence.

Performance highlights

• Exceptional spatial resolution and lesion detectability for precision medicine applications.
• High effective sensitivity with larger AFOV configurations enabling faster, lower-dose, or whole-body imaging.
• Integrated PET/CT design with CT axial coverage and fast rotation time to reduce acquisition and breath-hold times.

AI & workflow

• uExcel platform with multiple AI modules: uVision (AI patient modeling and auto isocenter positioning), EasyRange (auto scan-range planning), OncoFocus (respiratory-motion reduction and improved lesion quantification), NeuroFocus (head motion correction without external trackers), and uExcel DPR 2.0 (AI-enhanced reconstruction tuned with long AFOV data).
• AI-assisted patient positioning and automated planning to reduce manual intervention and improve throughput.

Clinical capabilities and examples
Demonstrated clinical use cases include fast whole-body imaging with clear delineation of small lesions, high-resolution PET/CT imaging for small lesion detection, half-dose total-body imaging in high BMI patients, clear delineation from vertex to toe, high-resolution brain imaging positioned at edge of AFOV, and dual-/dynamic-tracer imaging for oncology workflows.
