concept of radiation protection that states all exposures should be kept “as low as reasonably achievable

negative electrode in the x-ray tube

overall darkness or blackness of an image.

A negative charged shallow metal depression within the cathode of an x-ray tube that houses the filament.

Silver halide crystals

absorb radiation during x-ray exposure and store energy emitted from the radiation

highest voltage of x-ray tube used during an exposure

time between exposure to ionizing radiation and appearance of image

one one-thousandth (1/1000) of an ampere; a unit of measurement used to describe the intensity of an electrical current.

most penetrating beam produced at the target of the anode

image refers to structures that are less dense and permits the x-ray beam to pass through causing the images to appear dark or black.

Radiolucent , examples

Air, fat, soft tissues, and some types of infections or tumors in bones depressions, cavities, or openings in bone, like the sinus, canal, or foramen

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

x-radiation that is created when the primary beam interacts with matter

a common, fast, and painless imaging test that use a small amount of electromagnetic radiation to create images of the inside of the body

intraoral technique of exposing dental images where the x-ray beam is directed, perpendicular to an imaginary line which bisects the angle.

a common dental radiography error where part of the image receptor (film or sensor) is not exposed to the radiation beam, appearing as a clear or white, curved/straight border on the image

process by which electrons are removed from atoms, causing the harmful effects of radiation in humans.

mages are structures that are dense and resist the passage of radiation causing the image to appear light or white depending on the density

bone, amalgam fillings, implants, and braces.

Cephalometric radiograph

a specialized side-view X-ray of the head used mainly in orthodontics to capture detailed images of teeth, jawbones, and soft tissues

electronic signals captured by sensors and displayed on computer monitors
