Radiation - a form of energy carried by waves or stream of particles
X-radiation - a high-engery radiation produced by the collision of beam of electrons with a metal taget in
an x-ray tube
X-ray - a beam of energy that has the power to penetrate substances and record image shadows on
photographic film or digital sensors
Radiology - the scince or study of radiation as used in medicine
Radiograph - a two-dimensional respresentation of a three-dimensional object
Dental Radiograph - a photographic image produced on an image receptor by the passage of x-rays
through teeth and related structures
Radiography - the art and science of making radiographs by the exposure of film to x-rays
Dental Radiography - the production of radiographs of the teeth and adjacent structures by the
exposure of an image recerptor to x-rays
Dental Radiographer - any person who positions, exposes, and processes dental x-ray image receptors
Collimator - lead plate with a center hole that fits direcctly over the opening of the metal housing where
x-rays exit
X-ray Tube - heart of the x-ray generating system
, Tube Head - the tightly sealed heavy metal housing that contains the dental x-ray tube (holds the tube)
Tungsten Target - focal spot that converts election into photons or x-rays form (medal used for target)
Tungsten Filament - coils of tungsten that produces electrons when heated
Oil - surrounds x-ray tube and transformers (heat created during x-rays)
Unleaded Glass Window - a leaded-glass vacuum tube that prevents x-rays from escaping in all
directions (x-rays exit)
Aluminum Filters - placed in the path of the x-ray beam
PID (Cone) - open end lead line cylinder, retangular in shapes and sizes (16 long)
Copper Stem - dissipates heat away from tungsten target
Tube Head Seal (Aluminum) - permits exit of x-rays from the tube head (seals the oil)
Molybdenum Cup - focus electrons into a narrow beam and directs that beam across the tube toward
the tungsten taget of the anode
Vacuum - where you remove air
Cathode - negative electrade or charge (-) in a x-ray also contains the copper stem and the target
Anode - positive eletrade or charge (+) in a x-ray also contains the filement and the focusing cup
Extension Arm - x-ray tube head
