Radiology Flashcards
The study/science of radiation that deals with the use of X-rays, radioactive substances
Radiology
A form of energy carried by waves or stream of particules
Radiation
Person who positions, exposes, and processes dental xray film
Radiographer
Photographic image produced on a film by the passage of X-rays through teeth and related structures
Dental radiograph
The making of radiograph of the teeth and adjacent structures by the exposure of film to X-rays
Dental radiography
Beam of energy
X-rays
High energy radiation produced by the collision of a beam of e- with a metal target in an xray tube
X-radiation
Emission of a glowing light by certain substances when struck by a particular wavelength
Fluorescence
Uses of dental radiographs
Detect lesions/diseases/conditions
Confirm suspected disease
Localized lesions/foreign objects
Provide info during procedure
Evaluate growth/development
Condition of pt at a specific time
Pioneers in dental x- radiation and discoveries
Dr. Wilhelm- X-rays 1st discovered
Dr. O.Walkoff - dental radiograph
Dr. E. Kells- credit for dental rad,paralleling tech
Weston Prince -bisecting technique
Howard Riley -BW technique
Franklin W.McCormack- paralleling tech in dental rad
Gordon Fitzgerald -father of modern dental radiography. Long cone paralleling tech
Hisatugu Numata- pan
Yrjo Paatero- father of pan
Components parts of an I/O xray machine
Tube head
Extension arm
Control panel
Performance standards of dental xray machines
Equipment must be inspected and monitored periodically
Type of dental xray machines
I/O and E/O
Portable I/O units - to be used outside dental office
Components parts of an E/O xray machine
Tubehead
Positioning device- lateral head, chin, forehead, anterior teeth
Control panel
What’s a collimating device
Restricts size of xray beam to the size of an intraoral receptor thus limiting radiation exposure
