Shepp Logan Phantom Pins and Buttons

Description: The Shepp-Logan phantom is a popular numeric test image used in medical imaging for testing image reconstruction algorithms. It consists of several ellipsoids of varying grey levels and is supposed to represent a human skull. If you are a radiologist or interested in MRI, CT, X-ray or image processing, this design is for you. If you have a radiographer or medical engineer in your life, give it to them as a gift because radiology test images are rarely this cool-looking.
