What does the term radiographic mean?
(rā′dē-ō-grăf′) An image produced by radiation, usually by x-rays, and recorded on a radiosensitive surface, such as photographic film, or by photographing a fluoroscopic image. Also called radiogram, shadowgraph, skiagram, skiagraph.
What is the definition of a radiographic image?
1. Representation of an object made by the rays of light emanating or reflected from it. 2. Representation produced by x-rays, ultrasound, tomography, thermography, radioisotopes, or other modalities.
What is radiograph used for?
It is used to diagnose or treat patients by recording images of the internal structure of the body to assess the presence or absence of disease, foreign objects, and structural damage or anomaly. During a radiographic procedure, an x-ray beam is passed through the body.
Is a radiograph same as xray?
Non-imaging clinicians and the lay population generally use the term "x-ray" to refer to a radiograph, as well as for the radiation itself; e.g. a chest radiograph is often referred to as a chest x-ray. Radiograph is not used to describe dynamic images, which are usually referred to as fluoroscopic images.
What is the best definition for radiography?
Freebase. Radiography. Radiography is the use of X-rays to view a non-uniformly composed material such as the human body. A heterogeneous beam of X-rays is produced by an X-ray generator and is projected toward an object.
What is the study of radiography?
Radiography is the art and science of application of various form of radiation and waves on human being, animal and substances for the purpose of promotion of health, diagnosis and treatment of various forms of diseases in hospitals, non-destructive testing/detective scanning in industries and for research purpose.
What is general radiography?
General radiography, also known as plain film radiography, is the specialty within medical imaging that utilizes projectional radiography to examine anatomy. It is often referred to as simply 'x-ray' within medical imaging departments.
What is radiographic equipment?
In radiographic equipment, this comprises two sets of parallel blades made of high-attenuation material that can be driven into the beam to define the required (rectangular) area. The collimator incorporates a light source to the side of the X-ray beam and a mirror in the beam.
What is the principle of radiography?
It is based on the principle that radiation is absorbed and scattered as it passes through an object. If there are variations in thickness or density (e.g. due to defects) in an object, more or less radiation passes through and affects the film exposure.
Why radiography is important?
In today's medical field, doctors rely heavily on radiographers. They need accurate tests to be able to diagnose the issue and provide the proper treatment. Radiographers not only provide those tests, but they also provide an emotional and physical support while preparing patients for these tests.
How radiographic images are formed?
A radiographic image is created by passing an x-ray beam through the patient and interacting with an image receptor, such as an imaging plate in computed radiography (CR). The variations in absorption and transmission of the exiting x-ray beam structurally represent the anatomic area of interest.
Why is it called a radiograph?
Radiographs (originally called roentgenographs, named after the discoverer of X-rays, Wilhelm Conrad Röntgen) are produced by transmitting X-rays through a patient.
Is a CT a radiograph?
The CT scan is a more sophisticated and powerful X-ray that takes a 360-degree image of internal organs, the spine and vertebrae. Contrast dyes are often injected into the blood to make structures within the body more visible on the CT scan.
Is a CT scan a radiograph?
However, CT scans are a type of advanced x-ray devices doctors use for diagnosing internal organ injuries, using x-ray images of the structure and a computer. X-ray machines in some cases fail to diagnose problems with muscle damage, soft tissues or other body organs, but with the CT scan, it's entirely possible.
