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
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.
Use
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.
With the use of CT scans, doctors can determine a number of factors of a patient including brain activity, bone density and many others.
