- Applications of radiography include medical radiography and industrial radiography: if the object being examined is living, whether human or animal, it is regarded as medical; all other radiography is regarded as industrial radiographic work or Industrial computed tomography.uclear medicine typically involves gamma rays. The types of electromagnetic radiation of most interest to radiography are X-ray and gamma radiation. This radiation is much more energetic than the more familiar types such as radio waves and visible light.

Tomography Tomography refers to imaging by sections or sectioning, through the use of any kind of penetrating wave. The method is used in radiology, archaeology, biology, atmospheric science, geophysics, oceanography, plasma physics, materials science, astrophysics, quantum information, and other sciences. In most cases it is based on the mathematical procedure called tomographic reconstruction.

VT, PT, MT, UT, RT, IWI-C and IWE Ultrasound is often used for testing of steel, aluminum, plastics, composite materials and cast objects. Radiography (RT) Radiography is the method most often used for checking a weld connection or an object of internal errors / indications and volume errors. Radiography can be performed in two different ways, by X-ray with an x-ray tube, or by gamma used by an isotope.

Positron emission tomography Positron-emission tomography (PET) is a nuclear medicine functional imaging technique that is used to observe metabolic processes in the body as an aid to the diagnosis of disease. The system detects pairs of gamma rays emitted indirectly by a positron-emitting radionuclide , which is introduced into the body on a biologically active molecule.

- Radiography is a type of x-ray procedure, and it carries the same types of risks as other x-ray procedures. The radiation dose the patient receives varies depending on the individual procedure, but is generally less than that received during fluoroscopy and computed tomography procedures.hen an individual has a medical need, the benefit of radiography far exceeds the small cancer risk associated with the procedure. Even when radiography is medically necessary, it should use the lowest possible exposure and the minimum number of images.

Radiology Procedures An x-ray (radiograph) is a noninvasive medical test that helps physicians diagnose and treat medical conditions. Imaging with x-rays involves exposing a part of the body to a small dose of ionizing radiation to produce pictures of the inside of the body. X-rays are the oldest and most frequently used form of medical imaging.

- (October 2014). Radiography is an imaging technique that uses electromagnetic radiation other than visible light, especially X-rays, to view the internal structure of a non-uniformly composed and opaque object (i.e. a non-transparent object of varying density and composition) such as the human body.he types of electromagnetic radiation of most interest to radiography are X-ray and gamma radiation. This radiation is much more energetic than the more familiar types such as radio waves and visible light.

Computed Tomography Angiography (CTA) A computerized tomography scan, or CT scan, is a type of X-ray that uses a computer to make cross-sectional images of your body. The media injected to perform CT angiography is called a contrast material because it lights up blood vessels and tissues that are being studied.
