The Center for Quantitative Imaging (CQI) provides high-resolution X-ray computed tomography (CT) and advanced non-destructive testing to help industry partners visualize internal structures, quantify material properties, and solve complex quality and performance challenges.
The technology of microCT scanning creates high-resolution three-dimensional 3D images by using x-rays. To do this, the microCT scanner collects two-dimensional (2D) trans-axial projections (or slices) of the scanned material/specimen. Once collected, the slices are then reconstructed into a full 3D model.
Lab technicians work closely with clients to understand the objectives and offer the best possible solutions, collaborate on the process, and deliver the finest images.
Computed Tomography Users Group
Join the Penn State Computed Tomography (CT) Users Group, hosted by the Center for Quantitative Imaging (CQI). CT is a powerful imaging technique that creates high-resolution 3D images of anything from delicate fish specimens to complex electronics. This allows for a non-destructive examination of internal structures, providing valuable insights into their composition and function.
