The nano- and micro-Computed Tomography imaging core provides services for acquiring and quantitative analysis of three-dimensional images of biological and engineered materials, including metals, silica-based chips, scaffolds, and plastics. The core is capable of imaging mineralized tissues (e.g., bone, teeth); as well as soft tissues (e.g., tendons, ligaments, cartilage, blood vessels, muscle) with the aid of radiographic contrast agents.  Images can be acquired for both ex vivo and in vivo (microCT only) studies.  This core is managed and operated by members of the Orthopaedic Research Laboratories.
