What’s the spherical object with eyes? It’s called an MRI system phantom, which are scientific devices used by the biomedical research community that serve as stand-ins for humans. These devices contain materials like salt solutions or gels that mimic the responses of human tissue under specific conditions. They make sure that systems and methods used for imaging the human body, such as MRI scanners, are working like they’re supposed to and look for any changes in MRI systems over time. This spe
