1
Q

Radiation

A

Energy carried by waves or particles

2
Q

X-Radiation

A

High energy radiation produced by the collision of a beam of electrons with a metal target in an X-ray tube

3
Q

X-Ray

A

A beam of energy that has the power to penetrate substances and record image shadows on an image reception (film, sensor, or plate)

4
Q

Radiology

A

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

5
Q

Radiograph

A

An image or picture produced on a receptor (digital sensor, radiation sensitive film, or phosphor plate) by exposure of one of these image receptors to ionizing radiation

A TWO DIMENSIONAL REPRESENTATION OF A THREE DIMENSIONAL OBJECT

6
Q

Dental Radiograph

A

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

7
Q

Radiography

A

The science of making radiographs by the exposure of film to x-rays

8
Q

Dental Radiography

A

The production of radiographs of the teeth and adjacent structures by the exposure of film to x-rays

9
Q

Dental Radiographer

A

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

10
Q

Image

A

A picture or likeness of an object

11
Q

Image receptor

A

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

12
Q

Dental imaging

A

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

13
Q

Uses of dental Images

A

Detect lesions
Confirm or classify suspected disease
Localize lesions or foreign objects
Provide information during dental procedures
Evaluate growth. and development
Illustrate changes secondary to caries, periodontal disease, or trauma
Document the condition of a patient
Aid in development of a clinical treatment plan

24
Q

Bean alignment device

A

An instrument used to position the PID correctly

- Rinn XCP and BAI instruments

25
Q
