Study of X-rays or the field of X-rays is known as Radiography. X-rays are electro-magnetic waves with a wavelength of 0.10 – 10nm. X-ray tubes are used to generate X-rays which pass through a vacuum tube with a high voltage to accelerate the electrons produced at the cathode. These high velocity electrons hit a target of tungsten and rhenium at the anode which then produce the X-rays. Two types of X-rays are produced based on the type of alloy used at the anode. When Tungsten and molybdenum are used at the anode, softer X rays are produced which are used in mammography. A computer records the images that are created. When x-ray particles are passed through the bones it blocks the particles and appear white in color. Structure containing air will appear black in color. In the case of You do not have access to view this node, fat and fluid it will be in gray color.
X-ray test is performed in the hospitals or health care centers by a radiologist. The area where the image is required is projected under the x-ray machine and on the film the area and the images of the affected area are created. The images may appear blurred if there is motion in the body of the patient. So, patients are asked not move when they are exposed under the x-ray machine. X-rays allow doctors to look inside a patient’s body without requiring any surgery. X-rays are mainly used to see the broken bones in a patient’s body. X-rays are used for imaging various tissues, bones in the body. Computer Tomography is used for studying You do not have access to view this node, Fluoroscopy, another X-ray methodology is used to study artery blockages. Radiotherapy is used as a treatment in cancer to kill the malignant You do not have access to view this node.
There are some harmful side effects with exposure to X-rays. X-rays cause radiation sickness when patients are exposed to the x-ray radiation for a long period of time. The problem is that x-rays cause ionizing radiation. When X-rays hit an atom, they eject the electrons out of the atoms and forms ions. The formation of ions leads to chemical reactions inside the cells. This may break the DNA chains and the cell with broken DNA will die. And if this spreads through the body some of the cells will die and this may result in cancer which could spread throughout the body. X-rays can affect the egg cells which can lead to birth defects. But X-rays do provide a better alternative. Because of them surgery can be avoided which is a much costlier option to check inside the body. So X-rays are used in scanning instruments to detect any malformations or anything out of the ordinary in the body and also used to treat some of the diseases.
