EQUIP - Evaluation of Quality of Imaging on a Next-generation Total Body Pet Scan in Comparison to Conventional PET

The GE Healthcare Omni Total Body (TB) 128cms (Omni TB) is a long-axial field-of-view (LAFOV) PET/CT scanner and will be installed in a pre-market phase at the Peter MacCallum Cancer Centre. The main features and functionality of this new scanner include high sensitivity, high resolution digital detectors based on silicon photomultipliers. The ultra-high sensitivity and extended field of view are designed to support the ability to reduce administrated dose and/or shorten acquisition time without compromising the image quality of the PET imaging. To verify the appearance of images acquired on the Omni TB with images acquired on our conventional PET/CT equipment, a study imaging a cohort of patients on both devices is proposed. The study involves no additional radiopharmaceutical administration. Additionally, in keeping with ALARA (as low as reasonably achievable) radiation dose practices, it will be possible to model acquisition settings (duration, administered activity and reconstruction parameters) using the system raw data and a suite of research tools to optimise acquisition parameters.
