Traditional
X-rays image bones, but are poor at showing soft tissues. Computed Tomography
(CT) scanning uses a thin X-ray beam which is scanned around the subject,
effectively 'looking' from many different angles. X-rays passing through
the body are detected electronically. A computer reconstructs the stream
of signals from every angle to create an image 'slice' through the subject.
Many images slices may be combined to give a 3-D view of the body. CT
scanning allows some soft tissues to be studied more effectively, leading
to many advances in medical diagnosis in areas such as the brain. The
black and white images it produces may be coloured digitally to enhance
their information.
