Computed Tomography (CT)

Computed Tomography (CT) is a medical process for acquiring a far more detailed scan than with ordinary x-rays. This process acquires two-dimensional computer images that can be reconstructed to produce three-dimensional images. In a computed tomography (CT) screening a patient lies on a bed which is placed into the CT scanner, a machine that resembles a large doughnut. The body part that is being examined is placed in the round tunnel or opening of the CT scanner. The bed then slowly shifts forwards and backwards allowing the CT scanner to take pictures of the body. In a CT screening, the CT scanner obtains cross-sectional images of the body organs and tissues being examined. The use of CT scan equipment has allowed doctors to inspect a patient’s body without having to operate or performing unpleasant examinations. CT scanning has become an invaluable tool in carrying out such medical tasks as pinpointing the location of a tumor in a patient’s body.
