I chose this topic because I found it very interesting and wanted to know more. I had a CT scan when I had a concussion after a car accident when I was seven. Also because my father and many of my friends underwent CT scans. Anatomists, morphologists and biologists have tried to understand how living things live and what they look like on the inside. In 1974, Dr. Frourie laboriously cut organisms into thin slices to study their internal arrangement and understand them better. Today these people use CT scanners instead. It is much simpler, less bloody, takes less time and the sample is not damaged or destroyed during the procedure: the advantages are numerous. This technique allows us to visualize the insides of humans, organisms, or other objects in 3-D geometry. CTscans stands for "computed tomography". It's a way of looking inside your body using a special camera. It is an advanced computer and X-ray scanning system that creates detailed images of horizontal cross-sections of the body or part of the body subjected to informatics. A series of X-rays from many different angles are used to obtain these cross-sectional images of the patient's body. In a computer, these images are assembled into a three-dimensional image that can display organs, tissues, bones, and anything like that. It may also show ducts, blood vessels, and tumors. One of the advantages of CT is that it clearly shows the structures of soft tissues (such as the brain), as well as the structure of dense tissues (such as bones). Images from a Ctscanner are much more detailed than images from a regular X-ray machine. It can take photos of areas that are protected or surrounded by bones, which a regular X-ray machine cannot do. For this reason, a CT scanner is said to be 100 times more effective and intelligent than a normal x-ray and can therefore diagnose certain diseases much earlier and more quickly. It is recent technology that has made it possible to accurately scan objects into a computer in three dimensions, even though the machines and ideas were developed in the 1970s. In the 1970s doctors began using this new type of machine that could provide detailed images of organs that the older type of X-ray machine could not provide..
