Abdomen,CT scan. Coloured three-dimensional computed tomography (CT) scan of an abdomen in frontal view. The image shows (top to bottom),rib cage,liver,kidneys,lower spine,abdominal aorta,pelvis and femur joints. This image was produced using a multi-slice CT scanner,which uses a thin X-ray beam to scan around the patient to create 'slices' of the body. A computer reconstructs the slices into coloured three- dimensional images including bones and soft tissue. A contrast agent,injected into the patient,enables blood vessels to be detected by the CT scanner. The surgeon can navigate through the data by using a 'fly-through' animation of the images. This image was created using OsiriX medical imaging software |
