The Stanford University School of Medicine has a fascinating Flickr stream, including a collection of mystery medical history photos that I posted about several months ago. Most recently, they added a small set of interesting images from their 3D Radiology Lab. Above: "3D frontal view of teeth with braces overlaid on 2D human mandible. The wisdom teeth (upper right and left) have not yet penetrated the gums." Below left: "The lumbar region of the spine with surgically implanted hardware." From the 3D Radiology Set description:
The Stanford Radiology 3D Imaging Laboratory uses computed tomography and Magnetic Resonance imaging data to create three-dimensional images of the human body. Individual CT and MR scans of the body are taken around a single axis that are stacked and rendered using complex computer algorithms to create a three-dimensional volume of data. The images produced from this data can be manipulated on-screen to provide doctors with unique interior perspectives of the human body for diagnosing and treating patients. Each month the lab produces nearly 20,000 images.
