uMI Panorama

The uMI Panorama GS is an advanced diagnostic imaging system that integrates Positron Emission Tomography (PET) with an extended 148 cm axial field of view and Computed Tomography (CT) to provide comprehensive functional and anatomical information. Its design, featuring 504 PET detector rings and specialized support systems, aims to enhance image quality, accelerate scan times, and improve diagnostic capabilities across oncology, cardiology, and neurology, including functionality for low-dose CT lung cancer screening.

The uMI Panorama GS is a diagnostic imaging system that combines Positron Emission Tomography (PET) and Computed Tomography (CT) modalities. The PET component measures the quantitative distribution of radiopharmaceuticals within the patient's body, assisting healthcare providers in assessing metabolic and physiological functions. The CT component provides diagnostic tomographic anatomical information and photon attenuation data for the scanned region. The system facilitates accurate registration and fusion of PET and CT images, offering anatomical reference for PET findings. The uMI Panorama GS model features an extended 148 cm axial field of view (FOV) PET system with 504 detector rings using LYSO scintillator material, a significant increase from the predicate device's 120 rings and 35 cm FOV. This design aims to deliver high-quality functional and anatomical images, enable faster PET/CT imaging, and improve the overall patient experience. The integrated CT system is the uCT ATLAS Astound with a 40mm detector, which can also operate independently for standalone diagnostic CT imaging. The system is intended for use by qualified healthcare professionals to aid in the detection, localization, diagnosis, staging, restaging, treatment planning, and evaluation of treatment response for a variety of diseases, inflammations, infections, and disorders, particularly in oncology, cardiology, and neurology. It also supports low-dose CT lung cancer screening for early detection of lung nodules. The device includes a patient table with a 250 kg maximum load capacity and an upgraded power supply cabinet and chiller to meet the demands of the extended PET system. Non-clinical image performance testing was conducted to verify that the uMI Panorama GS met all its design specifications and demonstrated performance characteristics similar to its predicate device.
