Computed Tomography:
When
The very first step of the long process which scientists have taken to arrive at a CT scan starts with Alessandro Vallebona in 1930. He suggested taking a single slice of the body on radiographic film, which is known as tomography. The original prototype of a CT scanner was developed in 1971 and the first brain scan was performed in England at the Atkinson Morley Hospital in 1972.
How
The CT scan is an important tool used to supplement the use of x-rays and ultrasounds. It is used to create detailed images of the inside of an individual's body including their chest, abdomen, head, and other various parts of the body. These images can then be displayed on a computer using 3-d rendering techniques.
Use
This is a medical method used to scan the inside of an object using a large series of two-dimensional x-rays taken around a single axis.
With the use of CT scans, doctors can determine a number of factors of a patient including brain activity, bone density and many others. One of the most important factors of using a CT scan involves looking for abnormalities in the brain such as unnatural growths or lesioned areas.
