●● Dental radiography
Answer: The process of recording images of the teeth and adjacent
structures by exposure to radiation
●● Digital imaging
Answer: A filmless method of capturing an image and displaying it by
using an image receptor, electronic signal and a computer to process and
store the image.
●● Dose
Answer: The amount of energy absorbed by tissues.
●● Extension arm
Answer: Flexible arm that is attached to the x-ray tubehead
●● Image receptor
Answer: recording medium for an image, normally film, phosphor
storage plate or a digital sensor
,●● Intensity
Answer: The total energy of the x-ray beam.
●● Kilovoltage
Answer: Highest voltage of x-ray tube used during an exposure.

Answer: Time between exposure to ionizing radiation and appearance of
symptoms.
●● Lead apron
Answer: Device used to protect the reproductive and blood forming
tissues from scatter radiation.
●● Primary beam
Answer: The most penetrating beam produced at the target of the anode.
●● Quality
Answer: The mean energy of penetrating ability of the x-ray beam.
