Tungsten Target
A focal spot in the anode.
Atom
The basic unit of matter.
Central Ray
X-rays at the center of the beam.
Energy
The ability to do work.
Dose (of radiation)
The amount of energy absorbed by tissues.
Photon
A minute (tiny) bundle of pure energy that has no weight or mass.
Contrast
Difference in degrees of blackness on a radiograph.
Cathode
The negative electrode in the x-ray tube.
Kilovoltage
Highest voltage of radiograph tube used during a radiograph exposure.
Lead Apron
Device used to protect the reproductive and blood-forming tissues from scatter radiation.
X-Radiation
High-energy ionizing electromagnetic radiation.
Thyroid Collar
A flexible lead shield that is placed securely around the neck.
Magnification
The proportional enlargement of a radiographic image.
Master Switch, Indicator Light, Selector Buttons, Exposure Button
Components of control panel.
Density
The overall darkness or blackness of a radiograph.
Anode
The positive electrode in the x-ray tube.
Electron
A negatively charged particle in the atom.
Ion
An electrically charged particle.
Penumbra
The blurred or indistinct area that surrounds an image.
Radiology
The science or study of radiation as used in medicine.
Primary Radiation
Same as primary beam.
Somatic Effects
Effects of radiation that cause illness and are responsible for poor health (such as cancer, leukemia, and cataracts) but are not passed on to offspring.
Matter
Anything that occupies space and has a form or shape.
Primary Beam
The most penetrating beam produced at the target of the anode.
Radiograph
Image produced on photosensitive film by exposing the film to radiation and then processing it.
Ionizing Radiation
Radiation that produces ionization, resulting in harmful effects.
ALARA Concept
Concept of radiation protection that states that all exposures should be kept "as low as reasonably achievable".
Extension Arm
Flexible arm that is attached to the x-ray tubehead.
Radiation
Forms of waves of energy emission through space or material.
Tubehead
The part of the x-ray unit that contains the x-ray tube, the high-voltage and low-voltage transformers, and insulating oil.
Genetic Effects
Effects of radiation that are passed on to future generations through genetic cells.
Distortion
Change in the size of an image on a radiograph caused by incorrect vertical angulation.
Control Panel
The portion of the x-ray unit that contains the master switch, the indicator light, the selector buttons, and the exposure button.
Dental Radiography
The process of making radiograph of the teeth and adjacent structures by exposure to radiographs.
Ionization
Process by which electrons are removed from atoms, causing the harmful effects of radiation to humans.
Milliampere
One one-thousands (1/1000) of an ampere, a unit of measurement used to describe the intensity of an electrical current.
Sharpness
A measure of how well the radiograph reproduces the fine details or outlines of an object.
Secondary Radiation
X-radiation that is created when the primary beam interacts with matter.
Scatter Radiation
A form of secondary radiation that occurs when an x-ray beam has been deflected from its path by interactions with matter.
Bremsstrahlung Radiation
"Breaking radiation." The sudden deceleration of electrons as they interact with highly positively charged nuclei.
Digital Imaging
A filmless method of capturing an image and displaying it by using an image receptor, an electronic signal, and a computer to process and store the image.
Dosimeter
A device used to detect and measure an accumulated dosage of radiation.
Image
Film-based or digitally produced recordings of anatomical structures.
Image Receptor
A recording medium for an image, normally film.
Latent Period
Time between exposure to ionizing radiation and appearance of symptoms.
Radiation Monitoring Badge
A device that contains a film packet used to detect and measure radiation exposure of personnel.
Sensor
A solid-state image receptor that contains a silicon chip with an electric circuit.
