IMAG 1113 Chapter 1 Essential Concepts of Radiographic Science

Front

What is Radiography?

Back

Radiography is a type of X-ray exam that uses a solid state image receptor (IR) to produce fixed images.

Front

What is the definition of energy in the context of physics?

Back

Energy is the ability to do work.

Front

What does weight describe in physics?

Back

Weight is the force exerted on a body under the influence of gravity.

Front

What is irradiation?

Back

Irradiation is the process when matter intercepts radiation and absorbs all or some of the radiation.

Front

What is produced when a projectile electron from the cathode hits the anode target?

Back

The interaction produces X-rays.

Front

What is the primary purpose of fluoroscopy?

Back

Fluoroscopy is used to obtain real-time moving images of the interior of a patient.

Front

What is the difference between radiography and computed tomography (CT)?

Back

Radiography produces fixed images, while computed tomography (CT) creates cross-sectional images of the body.

Front

Define ionization in the context of radiation.

Back

Ionization is the process by which an atom or molecule gains or loses an electron, resulting in the formation of ions.

Front

What is the role of the anode in X-ray production?

Back

The anode serves as the target for projectile electrons, where X-rays are produced.

Front

What is the significance of the cathode in X-ray tubes?

Back

The cathode is the source of electrons in an X-ray tube, which are accelerated towards the anode.
