Digital Imaging (Chapter 25)

Front 1

A small detector that is placed intraoral to capture the radiographic image

Back 1

Sensor

Front 2

An image receptor found in the intraoral sensor

Back 2

Charge-Coupled Device (CCD)

Front 3

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 laster scans the plate and produces an image on a computer screen

Back 3

Storage Phosphor Imaging

Front 4

To convert an image into digital form that, in turn, can be processed by a computer

Back 4

Digitize

Front 5

A method of obtaining a digital image in which an intraoral sensor is exposed to x-rays to capture a radiographic image that can be viewed on a computer monitor

Back 5

Direct Digital Imaging

Front 6

A discrete unit of information; a picture element

Back 6

Pixel

Front 7

A method of obtaining a digital image, in which an existing radiograph is scanned and converted into a digital form using a CCD camera

Back 7

Indirect Digital Imaging

Front 8

A method of reversing the gray scale as a digital image is viewed

Back 8

Digital Subtraction

Front 9

A fimless imaging system; a method of capturing a radiographic image using a sensor, breaking the image into electronic pieces, and presenting and storing the image using a computer

Back 9

Digital Radiography

True or False: In digital imaging, the term used to describe the picture that is produced is radiograph

Back 10

False

Front 11

True or False: Digital imaging requires more x-radiation then does conventional radiography

False

Front 15

True or False: The preferred exposure method for intraoral digital imaging is the paralleling technique

Back 15

True

Front 16

True or False: One advantage of a digital imaging system is the superior gray-scale resolution that results

Back 16

True

Front 17

True or False: Digital subtraction is an advantage in digital imaging because distracting background information is eliminated from the image
