CT scans is a type of the non-invasive form of the medical test which helps to diagnose or to treat a particular disease. It includes x-ray and many other sophisticated computers which produce clear images and the internal organs of the body. After the images have been produced they are examined on the computer screen. This machine provides a clear image of the various blood vessels, bones and soft tissues etc. it is a the part of radiology. Through this machine the doctors can easily diagnose the diseases like cancer, brain tumor, appendicitis etc. It is the best equipment for examining the chest, pelvis and abdomen. It also shows some internal tissues of the body. This machine is basically a large box. In this box there is whole in it or you can call a short tunnel. The position of the x-ray detector and the x-ray tube is positioned on the opposite to each other. The workstation is positioned on another room. In this room the technologists operate the monitor and the scanner on the affected area. In most of the cases CT scan machine works like other x-ray machines. X-ray is done through passing radiation inside the body. It is like light radio waves. The different parts of the body absorb the radiation in different degrees. While this radiation is passed through the body it produces an image on the monitor which helps the doctor to find the affected area. Generally the bones appear on the x-ray sheet like white bones and the soft tissues appear in grey and air shows up in black. These x-ray beams or x-ray detector rotates around the body. With this CT scansmachine the monitor can measure the quantity of the radiation passing within the body. The CT scan machine involves a special process which is called spiral or helical CT scan. CT scan imaging system is generally compared to a loaf of the bread which can be cut into slices. When these images are shown through the monitor then it appears distinctly clean.
