Digital Radiography QUIZ Flashcards
Digital radiography has an advantage over film radiography because:
a. Storing and moving images is easier
b. Artifacts are not problematic in digital radiography
c. It is less expensive to set-up the processing equipment
Storing and moving images is easier
A technique problem that may occur with digital radiography could be caused by
a. Grid cut off
b. Patient motion
c. Scatter
d. All choices
All choices
DICOM standards refers to:
a. The computer system that stores digital radiography images
b. Radiation safety
c. The international standard for transmission of medical images
d. Training in the use of digital radiography equipment
The international standard for transmission of medical images
Digital radiography has a wide latitude, which means:
a. Changes in kVp have virtually no effect on image quality
b. There is no need for grids in digital radiography
c. Longer exposure times are needed for high image quality
d. Collimation has virtually no effect on image quality
Changes in kVp have virtually no effect on image quality
The Exposure Value Indicator (EPI) system indicates:
a. The quality of the image
b. The digital plates exposure to the x-ray beam
c. The patient’s exposure to the x-ray beam
d. ALARA has been achieved
The digital plates exposure to the x-ray beam
T/F: If a digital cassette (CR) is exposed on Friday, the image will be of perfect quality on Monday.
False
T/F: Unlike film radiography, digital radiography is not affected by white light.
False
T/F: Because the computer can label the images, there is no need to use lead markers on digital cassettes.
False
T/F: Digital radiography will always result in higher resolution than film radiography.
False
T/F: The decreased need for retakes due to exposure variables is a safety benefit of digital radiography vs. film radiography.
True
T/F: PACS (Picture Archiving and Communication System) is an advantage of digital radiography vs. film radiography.
True
