The Radiology Art project was started by artist and medical student Satre Stuelke in the Summer of 2007. Stuelke uses a CT scanner to acquire DICOM images of various objects (e.g., electronic apparatuses, toys) and then processes them with OsiriX Imaging Software and Adobe Photoshop. Colors are assigned based on the varying densities of materials present throughout the object. The post-processed images are stunning.
For example, here’s a CT scan of a Teslovak KT88S vacuum tube:
