Caption: Research specialist Susan Linden (L) checks on a Walker hound named Betty while veterinary surgeon Mandi Lopez (R) studies radiographs (colloquially known as x-rays) of Betty's knee, taken using a device dubbed DGY2000 which Lopez developed with veterinary surgeon Mark Markel and instrument specialist William Hagquist. The DGY2000 straps to a leg above and below a joint, allowing researchers or vets to apply a small force to just the tibia and x-ray the result, thereby detecting minor cruciate ligament damage before the ligament ruptures.

Caption: Two superimposed radiographs (colloquially known as x-rays) of a dog's knee were taken using a device dubbed DGY2000, developed by veterinary surgeons Mandi Lopez and Mark Markel with instrument specialist William Hagquist. The DGY2000 straps to a canine leg above and below a joint, allowing researchers or vets to apply a small force to just the tibia bone (at bottom) and x-ray the result. By comparing this radiograph to one in which no force is applied, movement in the joint as small as 0.1 millimeter is visible, thereby allowing vets to detect minor cruciate ligament damage before the ligament ruptures. In this case, movement of 5.4 mm indicates a ruptured cruciate ligament.
