MOLECUBES is a Ghent University spin-off, made possible by research valorization grants from iMinds, IWT and UGent-IOF. MOLECUBES builds preclinical imaging cubes, allowing SPECT, PET and CT imaging in almost any lab space. Its modular systems leave full flexibility while ensuring full mice and full rat imaging. Intuitive wireless acquisition and reconstruction software allow the systems to be used almost anywhere by anyone.
