ADC
Analog-to-Digital Converter; converts image info into numerical data
52
Also known as Positive Beam Limitation (PBL)
Automatic Collimation
53
Effect of motion on the radiolographic image
blur
54
Short for Potter-Bucky diaphragm; moving grid used to remove scatter radiation from the remnant beam, which can cause fog on IR,
Bucky; Gustave Bucky invented stationary grid, Hollis Potter invented moving grid
55
Light-proof container holding the IR, either an imaging plate for computed radiolographic or x-ray film and intensifying screens.
Cassette
56
Digital radograohic imaging using a cassette containing an image plate.
Computed Radiology (CR)
57
Differences in densities on a processed image.
Contrast; allows detail to be seen
58
CRT
Cathode ray tube (video monitor)
59
Opaqueness or degree of blackening on an area of the processed image.
Density
60
DICOM
Digital Imaging and Communications in Medicine, a standard protocol used for blending a picture archiving and communications system and various imaging modalities.
61
Uses fixed detectors that directly communicate with a computer.
Direct Digital Radiography (DR)
62
Misrepresentation of the size or shape of the object as recorded in the radiographic image.
Distortion; size= aka mag (OID+SID)
| shape= true distortion (mal-alignment of tube, part and or IR
63
S-number or exposure index that describes the status of the exposure and diagnostic value of the digital image.
Exposure Indicator
64
refers to film before exposure to radiation
Film
65
Area of the anode in the x-ray tube from which x-rays emnate
focal spot (focal track)
66
Device that is placed between the patient and the IR that absorbs scatter radiation that is exiting the body.
Grid
67
HIS
Hospital Information System
68
Graphic display of the distribution of pixel values.
Histogram
69
In radiology, this general term applied to any device or medium that captures the remnant beam.
IR
70
Device that is made of a photostimulable phosphor that absorbs the photon energies exiting the patient; is located inside a computed radiographic cassette.
Imaging Plate (IP)
71
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.
Intensifying Screens
72
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.
kVp
73
Digital image that is made up of rows and columns.
Matrix
74
Coverings worn by radiographers who are in a radiographic or fluoroscopic room with the x-ray beam turned on.
Lead Apron; the lead absorbs most of the scatter radiation that strikes the apron.
75
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.
mAs
76
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.
Object-to-Image Receptor (OID)
77
Picture Archiving and Communicating System
PACS
78
Picture element; the smallest component of a matrix.
Pixel
79
Digital manipulation of a radiographic image after its acquisition by the comoputer.
postprocessing image enhancement
80
machine that automatically develops x-ray film
processor
81
x-ray image as viewed after it has been exposed and processed.
Radiograph
82
specific position of the body or body part in relation to the table or IR.
radiographic position
83
path that the x-ray beam takes as it passes through the body; described as if the body is in the anatomic position.
radiographic projections
84
term used to explain how the IR sees the body image; the opposite of the radiographic projection
radiographic view
85
sharpness of structural lines as recorded on a radiograph
recorded detail (spatial resolution)
86
x-ray beam that exits the pt; is made up of image-forming rays and scatter radiation
remnant beam (exit radiation); makes contrast
87
radiology information system
RIS
88
Distance from source of radiation to the device that is detecting the radiation; this term is preferred over focal-film distance (FFD)
Source-to-Image Receptor Distance (SID)
89
Distance from the source of radiation to the part being examined; this term is preferred over focal-object distance (FOD)
Source-to-Object Distance (SOD)
| SOD+ OID=SID
90
Volume element; section of tissue represented by a pixel.
voxel
91
midpoint of densities in a digital image; used to adjust digital image brightness.
window level
92
Adjusts contrast of the digital image
window width (how much gray)
