Radiography Chapter 1

Radiation

A form of energy carried by waves or a stream of particles

X-Radiation

A high-energy radiation produced by the collision of a beam of electrons with a metal target in an x-ray tube

X-Ray

A beam of energy that has the power to penetrate substances and record image shadows on receptors (photographic film or digital sensors)

Radiology

The science or study of radiation as used in medicine; a branch of medicine science that deals with the therapeutic use of x-rays, radioactive substances, and other forms of radiant energy

Radiograph

An image or picture produced on a receptor (radiation-sensitive film, phosphor plate, or digital sensor) by exposure to ionizing radiation; a two dimensional representation of a three dimensional object

Dental Radiograph

A photographic image produced on a receptor by the passage of x-rays through teeth and related structures

Radiography

The art and science of making radiographs by the exposure of a receptor to x-rays

Dental Radiograpghy

The production of radiographs of the teeth and adjacent structures by the exposure of an image receptor to x-rays

Dental Radiographer

Any person who positions, exposes, and processes dental x-ray image receptors

Image

A picture or likeness of an object

Image Receptor

A recording medium; examples include x-ray film, phosphor plate, or digital sensor

Imaging, dental

The creation of digital, print, or film representations of anatomic structures for the purpose of diagnosis
