Feet, CT scan. Coloured three-dimensional computed tomography (CT) scan of adult feet. The scan shows the bones, ligaments and surface tissue. This image was produced using a multi- slice CT scanner, which uses a thin X-ray beam to scan around the patient collecting data from different angles to create 'slices' of the body. A computer reconstructs the slices into coloured three- dimensional images of the body, including bones and soft tissue. This image was created using OsiriX medical imaging software which allows surgeons to navigate around the body using fly- through animations of the data.
