Four 3-D CT (computed tomography) scans of the chest showing normal lungs: bone is coloured blue,the lungs in yellow & the aorta in red. CT scanning provides clear cross-sectional images of the body. X-ray beams are passed through the body in a circular track; the amount of X-rays absorbed by different tissues is recorded by detectors in the scanner and transformed via a computer into 2- & 3-D images. These images were produced on a Twin CT scanner,a device with a double source/detector system that affords reduced scan times,improved image contrast & resolution & the ability to resolve organ volume | |
