The world’s highest sensitivity, highest resolution PET scanner
The GNEXT PET/CT is the latest generation of high performance microPET scanners. Over the past decade, preclinical PET has established its value in a wide range of applications. Today’s PET/CT scanner must provide not only superior performance, but also a seamless workflow experience that holds both the animal and user experience as high as the specifications. Xodus achieves this with our newest G-Series system, GNEXT PET/CT. Utilizing a unique Depth-of-Interaction (DOI) method, we are able to better determine the correct line of response in PET coincidence detection, leading to more accurate positioning and better resolution across the field of view. With the GNEXT PET/CT, you will unlock applications in imaging small spontaneous tumors, lymph nodes, brain, cell tracking, and close to hot organs.
Diverse Applications
The GNEXT PET/CT is a large bore PET/CT scanner that can support single animals, multiple mice, multiple rats, rabbits, and small non-human primates. A variety of study designs and isotopes can be imaged and quantified.

Simplified, Elegant Workflows
Quickly define complex protocols with just a few clicks, or use preset protocols provided with the software. Then reuse those protocols for your entire study so that you can focus on scanning, eliminating the burden of repetitive data entry. All PET data is collected in list mode format and images are stored in DICOM format, allowing for export and analysis on your analysis software of choice, such as VivoQuant™.
Get ultimate system flexibility with multiple modes of operation. The GNEXT workstation is powerful enough to run both acquisition and reconstruction simultaneously with options for a variety of reconstruction protocols.
