digital imagining, dental film & processjng radiographs

Question 1

automatic processor

Answer 1

-automates all film processing steps

Question 2

beam alignment device

Answer 2

-assist in positions of the PID in relation to tooth and film or sensor

Question 3

bitewing

Answer 3

-

Question 4

calcium tungstate

Answer 4

-A common type of phosphor which produces a blue light

Question 5

cassette

Answer 5

-plastic or metal case that is used to hold the film and protect it from exposure to light also holds the film in tight contact with the intensifying screen

Question 6

cephalometric film

Answer 6

-shows the bony and soft tissue areas of the facial profile

Question 7

charge-coupled device (CCD) DIGITAL IMAGING

Answer 7

-most commonly used digital receptor

used in telescopes fax video camera

has a cable connected directly from the sensor to the computer

use radio frequency transmission to instantly transmit the image to the computer via image waves

Question 8

digital image/radiograph

Answer 8

-electronic signals captured by sensors and displayed on a computer screen almost ASAP

(what we email out)

Question 9

digitized

Answer 9

desktop scanner captures the light of signal off whatever’s placed inside them

Question 10

duplicating film

Answer 10

used only in a dark room setting it is never exposed to x-rays

sensitive to light and has emulsion on one side only

Question 11

extraoral film

Answer 11

-placed outside the mouth during x-ray exposure used to examen large areas of head or draw including panoramic or cephalometric films

Question 12

film speed

Answer 12

-The amount of radiation that is required to produce a radiograph of standard density (darkness )

determines how much exposure time is required to produce the image on the film

Question 13

intensifying screen

Answer 13

-A device that intensifies or increases the effect of radiation in those decreases the amount of exposure time needed

Question 14

intraoral film

Answer 14

-semi-flexible acetate film base that is coated on both sides with an emulation of silver bromide, silver halide, and silver iodide that is sensitive to radiation

film placed inside the mouth used to exam in the teeth in supporting structures

Question 15

label side

Answer 15

-The side that has a flap that is used to open the film packet before processing. The label side is the color-coded side that is used to identify films

Question 16

latent image

Answer 16

-The invisible image that is produced when radiation interacts with the silver Halide crystals in the film emulsion

Question 17

occlusal

Answer 17

—

Question 18

panoramic film

Answer 18

-

Question 19

periapical

Answer 19

-

Question 20

phosphor storage plates (PSPs)

Answer 20

-image receptor is a thin flexible plate, size of x-ray film, coated with phosphor crystals

phosphor layer is able to store the energy of the x-ray photons for a lil

a scanner “reads” the info stored on plate using laser beam to release the energy from plate into digital image

latent image remains in phosphor plate before scanning for minutes to hours depending on environment

do not store in bright light or warmth - releases energy

BARRIER ENVELOPE

Question 21

positioning device/positioning instrument (dental film & sensor holders)

Answer 21

-used to position & hold x-ray films or digital sensor in patients mouth

Question 22

processing

Answer 22

-A series of steps that change the latent image on the exposed film into a radiograph by producing a visible image on the film

Question 23

teledentristy

Answer 23

-

Question 24

tube side

Answer 24

-Solid why has the raised bumps on one corner. when placed in the mouth the white side of the film faces towards the teeth and tube head and the raised dot points toward the incision/occlusion surface

Question 25

-direct digital

Answer 25

solid slate sensor is is the image receptor

CCD sensor used
