What are the 3 components of the x-ray machine

The control panel, The tubehead, an extension arm

The ___ is the negative electrode in the x-ray tube

Cathode

The __ is the positive electrode in the x-ray tube

Anode

The __ is a metal disc with a small opening in the center to control the size and shape of the x-ray beam as it leaves the tubehead

Collimator

Lead lined __ is used to aim the x-ray beam at the film in the patient’s mouth

PID (position indicator device)

What is Milliamperage (mA)

A measure of the intensity of the electrical current passing through the tungsten filament

What is Kilovoltage (kVp)

Selector is used to control the penetrating power of the x-ray beam

__ is a form of secondary radiation that occurs when an x-ray beam has been deflected from its path by interaction with matter

Scatter radiation

__ structures allow x-rays to pass through them

Radiolucent

__ structures DO NOT allow x-rays to pass through them

Radiopaque

__ is the overall blackness or darkness of an image

Density

The fuzzy or blurred area that surrounds an image is called the __

Penumbra

List the 3 types of film

Intraoral, Extraoral, Duplicating

What are the two basic methods of acquiring a digital x-ray image?

Direct imaging and Indirect imaging

__ shows a panoramic view of the upper and lower jaws on a single radiograph

Panoramic film

An __ intensifies or increases the effect of the radiation thus decreases the amount of exposure time needed

Intensifying screen

A __ is a plastic or metal case used in extraoral radiography to hold the film and protect it from exposure to light
