What is meant by radiography testing?

Radiographic Testing (RT) is a non-destructive testing (NDT) method which uses either x-rays or gamma rays to examine the internal structure of manufactured components identifying any flaws or defects. In Radiography Testing the test-part is placed between the radiation source and film (or detector).

What is the meaning of Radioscopy?

Medical Definition of radioscopy : direct observation of objects opaque to light by means of some other form of radiant energy (as X-rays)

What is the difference between radiography and radioscopy?

Fundamentally, radiography is an off-line, static examination technique, while radioscopy is a dynamic examination technique with the potential for on-line examination and process control.

What is a 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.

Where is radiographic testing used?

Radiographic testing is widely used in a variety of industry sectors including aerospace, power generation, construction, petroleum, chemical and automotive, and for all types of components and parts.

What are the types of radiography?

Medical radiography includes a range of modalities producing many different types of image, each of which has a different clinical application.

• Projectional radiography.
• Computed tomography.
• Dual energy X-ray absorptiometry.
• Fluoroscopy.
• Contrast radiography.
• Other medical imaging.
• Shielding.
• Campaigns.

How is fluoroscopy different from radiography?

Radiography or X-ray and fluoroscopy procedures seem similar. However, fluoroscopy obtains moving images of the inner part of the body and radiography uses gamma rays to develop a static image of the internal structure of a body.

What is difference between radiologist and radiographer?

1. Radiology is a specialized field of medicine while radiography is a technology used in medicine. 2. Radiology is the diagnosis and treatment of diseases while radiography is the production of images of body organs which form as the basis for radiologists in the diagnosis and treatment of certain ailments.

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.

What are the three basic rules of radiography?

Three basic principles should be adhered to when dealing with radiation and making radiographs: • Time • Distance • Shielding. These principles form the basis of a broader radiation safety concept called aLaRa (as Low as Reasonably achievable).

What is the principle of radiographic testing?

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. Flaws show up on the film, usually as dark areas.
