Introduction To Digital Radiography And PACS -
Questions With Correct Solutions
Conventional Film/Screen Radiography Correct Answer - Uses film and
screens for image production.
Film/Screen (F/S) Correct Answer - Film placed between intensifying
screens for exposure.
Intensifying Screens Correct Answer - Emit light when struck by x-rays,
exposing film.
Digital Imaging Correct Answer - Electronic image acquisition process
for manipulation.
Computed Tomography (CT) Correct Answer - First digital imaging
technique developed in the 1970s.
Picture Archiving and Communication System (PACS) Correct Answer -
System for storing and transmitting medical images.
Hounsfield Correct Answer - Developer of the first CT scanner
technology.
Magnetic Resonance Imaging (MRI) Correct Answer - Introduced in the
early 1980s for imaging.
Analog-to-Digital Converters Correct Answer - Enable digital capture of
fluoroscopic images.
Teleradiology Correct Answer - Transmitting images via telephone lines
remotely.
Photostimulable Phosphor (PSP) Correct Answer - CR technology that
captures x-ray energy accurately.
, PSP Reader Correct Answer - Device that reads stored x-ray energy
from PSP.
Flat Panel Detectors (FPDs) Correct Answer - Utilizes x-ray absorbers
and TFT/CMOS for imaging.
Indirect Capture DR Correct Answer - Converts x-rays to light, then to
electric signals.
Direct Capture DR Correct Answer - Photoconductor converts x-rays
directly to electrical signals.
Sensitivity Speck Correct Answer - Attracts silver ions during film
processing.
Manifest Image Correct Answer - Final image produced after chemical
processing of film.
Storage Phosphor Plates Correct Answer - Store x-ray energy similar to
intensifying screens.
Efficiency Ratings Correct Answer - FPD systems are more efficient than
F/S and PSP.
Viewing Station Correct Answer - Where digital images are displayed
and analyzed.
Technologist QC Workstation Correct Answer - Quality control area for
technologists to manage images.
Chemical Processing Correct Answer - Process that develops latent
images into visible images.
PSP Correct Answer - Photostimulable phosphor used for image
capture.
Barium Fluorohalide Correct Answer - Material used in PSP for x-ray
detection.
