Positron Emission Tomography (PET) is a wonderful molecular imaging technology, instrumental to tackle cancer and other diseases. We believe it should be much more available and easier to use.
We're a spin-out from the University of Aveiro developing uniquely compact and affordable high-resolution PET systems. Our innovative scanning method allows high performance imaging while reducing complexity, weight and costs by more than 5 times, enabling a more flexible and broader use of this powerful technology.
Our mission is to WIDEN ACCESS TO PET IMAGING, reducing gaps and improving biomedical research and diagnostics worldwide, particularly of cancer and neurodegenerative diseases.
