New Georgia Tech micro-CT imaging technique to help tissue engineers improve bone regeneration
... optimum combination requires improved methods for tracking the healing process. New Georgia Tech research points to better ways to heal and regenerate bones using microcomputed tomography (micro-CT) imaging — a process 1 million times more detailed than a traditional CT scan.
