a small detector that is placed intraorally to capture the radiographic image
an image receptor found in the intraoral sensor
charge coupled device
a form of indirect digital imaging in which the image is recorded on phosphor coated plates and then placed into an electronic processor where a laser scans the plate and produces an image on a computer screen
storage phosphor imaging
to convert an image into digital form that in turn can be processed by a computer
a method of obtaining a digital image in which an intraoral sensor is exposed to xrays to capture a radiographic image that can be viewed on a computer monitor
direct digital imaging
a discrete unit of information; a picture element
a method of obtaining a digital image in which an existing radiograph is scanned and converted into a digital form using a CCD camera
indirect digital imaging
a method of reversing the gray scale as a digital image is viewed
a filmless imaging system; a method of capturing a radiographic image using a sensor, breaking it into electronic pieces, and presenting and storing the image using a computer
t/f in digital radiography, the term used to describe the picture that is produced is radiograph.
t/f digital radiography requires more xradiation than conventional radiography
false-requires less xradiation
t/f the xradiation source used in most digital radiography systems is a conventional dental xray unit
t/f compared with film emulsion, the pixels used in digital radiography are structured in an orderly arrangement.
t/f all intraoral sensors can be heat sterilized after use
false-cannot be sterilized must use a barrier
t/f the preferred exposure method for intraoral digital radiography is the paralleling technique
t/f one advantage of a digital radiography system is the superior gray scale resolution that results
t/f digital subtraction is an advantage in digital radiography because distracting background information is eliminated from the image
t/f the manipulation of the original digital image can be considered a legal issue
what year was digital radiography introduced to dentistry?
digital radiography can be used for:
D. all of the above
why does digital radiography requires less radiation than conventional radiography?
the sensor is more sensitive to xrays (so the time can be decreased)
the method of obtaining a digital image similar to scanning a photograph to a computer screen is termed?
indirect digital imaging
the image receptor found in the intraoral sensor is termed:
digital radiography systems can be used for which of the following?
D. all of the above-digital systems are not limited to intraoral!
all of the following are advantages of digital radiography except:
