Definition of X Rays – Introduction to fundamental concepts of Biological Science including the organization and common characteristics of living matters, cell structures and functions, food production by photosynthesis, harvesting energy, mechanism of cells reproduction, genetics, evolutions, and Human Biology. Introduction to general chemistry including basic concepts about matter, atomic structure, chemical bonds, gases, liquid, and solids, solutions, chemical reactions, acid, bases, and salt;
organic and biochemistry including hydrocarbons and their derivatives, carbohydrates, lipids, proteins, enzymes, vitamins, and minerals, nucleic acids; principles of physics and applications to nursing including gravity and mechanics, pressure, heat and electricity; nuclear chemistry and nuclear physics, effects of radiation on human beings, and protection and disposal. The aim of the course is to acquire knowledge and skills in general biological science, general chemistry and physics.
Definition of X Rays
X-rays are a type of radiation called electromagnetic waves. X-ray imaging creates pictures of inside the body.
Or
X-rays are types of electromagnetic radiation probably most well-known for their ability to see through a person’s skin and reveal images of the bones beneath it.
Uses of X-Rays
- Identifying fractures (cracks) and breaks or infections in bones and teeth
- Diagnosing cavities and evaluating structures in the mouth and jaw
- Picking up on signs of joint changes that indicate arthritis using a special type of X-ray image called an arthrogram
- Revealing tumors on bones
- Measuring bone density as a means of diagnosing osteoporosis
- Finding evidence of pneumonia, tuberculosis, or lung cancer (chest X-rays)
- Examining breast tissue for signs of cancer using a special X-ray technique called mammography
- Looking for signs of heart failure or changes in blood flow to the lungs and heart
- Revealing problems in the digestive tract such as kidney stones, sometimes using a contrast medium called barium
- Locating swallowed items such as a coin or tiny toy
Types of X-Rays
There are many types of X-rays that are used to diagnose conditions and diseases. The following are examples.
1. Mammography: It is a type of X-ray radiograph that is used to detect breast cancer.
2. Computed tomography (CT) scans: Computed tomography (CT) scans combine X-ray with computer processing to create detailed pictures (scans) of cross sections of the body that are combined to form a three-dimensional X-ray image.
3. Fluoroscopy: Fluoroscopy uses X-rays and a fluorescent screen to study moving or real-time structures in the body, such as viewing the heart beating. It can also be used in combination with swallowed or injected contrast agents to view the digestive processes or blood flow. Cardiac angioplasty uses fluoroscopy with a contrast agent to guide an internally threaded catheter to help open clogged arteries. Fluoroscopy is also used to precisely place instruments in certain locations within the body, such as during epidural injections or joint aspirations.
