LMRT DIGITAL RADIOGRAPHY
(SECTION 4) EXAM QUESTIONS AND
ANSWERS GRADED A+ 2025/2026
What is digital radiography imaging? - ANS Any imaging acquisition process that produces an
electronic image that can be viewed and manipulated on a computer
Detectors measure and convert x-ray data into what? - ANS Electronic (analog) signals
What is data acquisition? - ANS Collection of x-rays transmitted through the patient and is the
first step in the production of the image
What is conversion in regards to digital radiography? - ANS It is the function of the analog-to-
digital converter
What are the 2 categories Flat panel detectors (FPD) is divided into? - ANS 1. Indirect Capture
2. Direct Capture
What is indirect capture? - ANS It is a detector that produces light when struck by x-rays and
then the light is captured and converted to an electrical charge

, What is direct capture? - ANS A detector that captures the x-ray energy and converts it
directly to an electrical signal
What are PACS? - ANS A networked group of computers, servers, and archives that can be
used to manage digital images
What are DICOMS? - ANS A standard that allows imaging modalities and PACS to
communicate in the same language
What are PACS made up of? - ANS Reading stations, physician review stations, web-access,
and many things used in the hospitals
What storage systems do PACS use? - ANS RAID (Redundant array of independent disks)
What is the input image? - ANS The data collected during imaging is first converted into
digital data for input into a computer
What is the output image? - ANS Result of computer processing
What is analog images? - ANS Made up of continuous, varied levels of brightness and colors
What are digital images? - ANS Images captured that represent a finite number of bits of
information
True or False
For analog systems, x-ray energy is converted to light and recorded on the film - ANS True
