Computerized (or computed) tomography, and mostly formerly referred to as computerized axial tomography (CAT) scan, is an X-ray process that mix up many X-ray images along with the help of a computer to produce cross-sectional views and, in case needed, three-dimensional images of the inside organs and structures of the body. Computerized tomography is much more commonly known by its abbreviated terms or names, CT scan or CAT scan. A CT scan is extensively used to define general and abnormal structures in the body or it helps in assisting in procedures by assisting to properly guide the placement of instruments or treatments.
A massive donut-shaped X-ray machine or scanner does take X-ray images at various different angles around the body. These pictures or images are processed by a computer to generate cross-sectional pictures of the body. In every single of these pictures the body is seen as an X-ray “slice” of body, and it is recorded on a film. Such a recorded image is known as a tomogram. “Computerized axial tomography” is all about the recorded tomogram “sections” at varied levels of the body. Once you go through CT scan in Bangalore or in your city; you will feel the advancement of this medical procedure.
