Portable, Self-contained Upright PET Imaging System with Integrated Augmented Reality and Motion Tracking

Background & Unmet Need

• Traditional PET imaging requires patients to lie flat for extended periods, causing discomfort and requiring significant immobilization
• Conventional PET setups are large, fixed installations requiring dedicated scanner rooms, workstations, and technician operation rooms
• Current systems lack mobility and flexibility, limiting their use in outpatient or non-traditional settings
• Unmet Need: A mobile, self-contained PET imaging system that can accommodate patients who cannot lie flat without compromising image quality

Technology Overview

• Technology: A portable, upright PET imaging system featuring integrated motion tracking and augmented reality capabilities, designed for seated or partially reclined imaging positions.
• A prototype system has been designed and constructed to validate the concept
• The system features a compact upright gantry mounted on a mobile cart with an integrated foldable chair
• Real-time electromagnetic tracking enables sub-millimeter motion correction during scanning
• Built-in lead shielding provides radiation protection for nearby personnel
• An integrated AR headset enhances patient engagement and comfort during procedures
• A comprehensive control center manages synchronized data acquisition and system monitoring

Technology Applications

• Outpatient PET imaging in non-traditional settings, such as clinics or mobile diagnostic units
• Dynamic imaging studies requiring patient interaction or movement
• Clinical applications requiring upright positioning, including patients who need head movement flexibility or cannot lie flat (such as pediatric cases or those with specific medical conditions)

Technology Advantages

• Enhanced mobility and flexibility - can be wheeled to any location as a self-contained unit
• Improved patient comfort and accessibility through upright positioning
• Superior image quality despite patient movement through real-time motion correction
• Reduced space requirements compared to traditional PET installations
