Smoking is the most common cause due to which lung cancer is occurs, it can be seen by the stats i.e. more than 80% of cases. The reason for this is as cigarette smoke contains many chemicals which affects our body's way of filtering the air in the lungs. Smoke not only irritates lungs but also produce the mucus in large amount. It has the ability to paralyses the hair like tiny structure known as cilia whose purpose is to clean the lungs from dust and dirt. So this leads to accumulation of the toxic dust or dirt due to smoke to blockage and congestion the lungs as paralysis of lung functioning. This kind of symptoms are generally tend to This extra mucus means chronic bronchitis also called with the name of 'smoker's cough'. Asthma is also …show more content…
Medical imaging allows us to view the internal structures hidden by the skin and bones, as well as to diagnose and treat the disease these imaging also establishes a database of normal anatomy and physiology to make it possible to identify abnormalities. Although imaging of removed organs and tissues can be performed for medical reasons, such procedures are usually considered part of pathology instead of medical …show more content…
X-rays are oldest and best known for the use in medical diagnostics, like astronomy. X-rays are generated from the X-ray tube for the medical image processing consisting a vacuum tube with anode and cathode, by heating cathode, it release free electron which flow at a very high speed toward the positive charge anode. When the electron penetrates or strike on nucleus the released energy is known as x-rays radiation. The penetrating power could be adjusted by applying voltage across the anode, and number of x-rays is controlled by applying current to the filament of cathode. Generation of X-ray images is simply taken by placing the patient between the x-ray source and a film sensitive to x-ray energy. Due this process the intensity of x-ray is modified by the absorption as it pass through the patient and rest resulting energy fall on the film develop the image similarly as the light develops the photographic film, then the modernization of the X-ray is done and CT scan is discovered which is known as Computer tomography or computerized axial tomography is a method of forming image from X-rays. They contain the measurement from the X-ray transmitted rays through the body, such that they contain information about body during the path of X-ray beam. In computed tomography (CT), a number of 2D radiographs are acquired by rotating the X-ray tube around the body of the
