A

Analog-to-Digital Converter; converts image info into numerical data

52
Q

Also known as Positive Beam Limitation (PBL)

A

Automatic Collimation

53
Q

Effect of motion on the radiolographic image

A

blur

54
Q

Short for Potter-Bucky diaphragm; moving grid used to remove scatter radiation from the remnant beam, which can cause fog on IR,

A

Bucky; Gustave Bucky invented stationary grid, Hollis Potter invented moving grid

55
Q

Light-proof container holding the IR, either an imaging plate for computed radiolographic or x-ray film and intensifying screens.

A

Cassette

56
Q

Digital radograohic imaging using a cassette containing an image plate.

A

Computed Radiology (CR)

57
Q

Differences in densities on a processed image.

A

Contrast; allows detail to be seen

58
Q

CRT

A

Cathode ray tube (video monitor)

59
Q

Opaqueness or degree of blackening on an area of the processed image.

A

Density

60
Q

DICOM

A

Digital Imaging and Communications in Medicine, a standard protocol used for blending a picture archiving and communications system and various imaging modalities.

61
Q

Uses fixed detectors that directly communicate with a computer.

A

Direct Digital Radiography (DR)

62
Q

Misrepresentation of the size or shape of the object as recorded in the radiographic image.

A

Distortion; size= aka mag (OID+SID)

shape= true distortion (mal-alignment of tube, part and or IR

63
Q

S-number or exposure index that describes the status of the exposure and diagnostic value of the digital image.

A

Exposure Indicator

64
Q

refers to film before exposure to radiation

A

Film

65
Q

Area of the anode in the x-ray tube from which x-rays emnate

A

focal spot (focal track)

66
Q

Device that is placed between the patient and the IR that absorbs scatter radiation that is exiting the body.

A

Grid

67
Q

HIS

A

Hospital Information System

68
Q

Graphic display of the distribution of pixel values.

A

Histogram

69
Q

In radiology, this general term applied to any device or medium that captures the remnant beam.

A

IR

70
Q

Device that is made of a photostimulable phosphor that absorbs the photon energies exiting the patient; is located inside a computed radiographic cassette.

A

Imaging Plate (IP)

71
Q

Mounted in the cassette singly or in parts, these screens glow with visible light when struck by radiation and expose the film contained in the cassette.

A

Intensifying Screens

72
Q

Peak kilovoltage that is applied to the x-ray tube, which determines the wavelength of the x-ray beam, its ability to penetrate the body, and the overall contrast of the radiographic image.

A

kVp

73
Q

Digital image that is made up of rows and columns.

A

Matrix

74
Q

Coverings worn by radiographers who are in a radiographic or fluoroscopic room with the x-ray beam turned on.

A

Lead Apron; the lead absorbs most of the scatter radiation that strikes the apron.

75
Q

Milliampere seconds; the product of milliamperage and time; mA is the current that is passed through the x-ray tube, which is then converted to when it strikes the anode; it determines the number of x-rays produced and, consequently, the overall darkness of the resulting radiograph; radiation exposure to the pt is directly proportional to the mA used.

A

mAs

76
Q

Distance from the part being examined to the device hat is detecting the radiation; this term is preferred over object-film distance (OFD) because some imaging modalities do not use film as the primary IR.

A

Object-to-Image Receptor (OID)

77
Q

Picture Archiving and Communicating System

A

PACS

78
Q

Picture element; the smallest component of a matrix.

A

Pixel

79
Q

Digital manipulation of a radiographic image after its acquisition by the comoputer.

A

postprocessing image enhancement

80
Q

machine that automatically develops x-ray film

A

processor

81
Q

x-ray image as viewed after it has been exposed and processed.

A

Radiograph

82
Q

specific position of the body or body part in relation to the table or IR.

A

radiographic position

83
Q

path that the x-ray beam takes as it passes through the body; described as if the body is in the anatomic position.

A

radiographic projections

84
Q

term used to explain how the IR sees the body image; the opposite of the radiographic projection

A

radiographic view

85
Q

sharpness of structural lines as recorded on a radiograph

A

recorded detail (spatial resolution)

86
Q

x-ray beam that exits the pt; is made up of image-forming rays and scatter radiation

A

remnant beam (exit radiation); makes contrast

87
Q

radiology information system

A

RIS

88
Q

Distance from source of radiation to the device that is detecting the radiation; this term is preferred over focal-film distance (FFD)

A

Source-to-Image Receptor Distance (SID)

89
Q

Distance from the source of radiation to the part being examined; this term is preferred over focal-object distance (FOD)

A

Source-to-Object Distance (SOD)

SOD+ OID=SID

90
Q

Volume element; section of tissue represented by a pixel.

A

voxel

91
Q

midpoint of densities in a digital image; used to adjust digital image brightness.

A

window level

92
Q

Adjusts contrast of the digital image

A

window width (how much gray)
