X-ray Image Characteristics
Unsharpness, or blurring of the edges in a dental image.
What is Prenumbra?
A device used to hold and align intramural dental x-ray receptors in the mouth.
What is receptor holder?
Fastest intraoral film available.
What F- speed?
The pattern of stored energy on the exposed film cannot be seen.
What is latent image?
How sharply dark and light areas are differentiated or separated on an image.
What is contrast?
The most radiolucent part of a tooth.
What is the dentin?
Type of receptor placed in the mouth.
What is intraoral?
To emit visible light in the blue or green spectrum.
What is fluoresce?
The 5 steps for manual film processing in order.
What is development, rinsing, fixing, washing, drying?
The number of x-rays produced in the dental x-ray unit.
What is quantity?
The smaller the focal spot...
What is the sharper the image?
An extraoral X-Ray machine.
What is a panoramic machine?
A special device that is used to hold the extra oral film and the intensifying screens.
What is cassette?
White spot that appear on dental image films are referred to as this.
What is air bubbles?
The term used to describe the mean energy or penetrating ability of the x-ray beam.
What is quality?
A dental image with low contrast has this.
What is many shades of gray?
The year federal standards were implemented for dental x-ray machines.
What is 1974?
The 3 things films are adversely affected by.
What is heat, humidity, and radiation?
A low-intensity light composed of long wavelengths in the red-orange portion of the visible light spectrum.
What is safelighting?
Milliamperage and exposure time are related this way.
What is inversely?
Increasing miliamperage will cause this in density.
What is high density?

What is film base, adhesive layer, film emulsion, and protective layer?
Chemical found in the developing agent that generates the many shades of gray of the radiographic image.
What is Elon?
Termed by reducing the intensity of the x-ray beam by half.
What is half-value layer?
