RTBC Image Evaluation and Quality Control-
Questions & Answers
What is the process called that identifies the values of interest in a radiographic histogram?
✔️Correct Ans-histogram analysis
Determining that the correct body part is examined during a radiographic procedure is the
responsibility of the: ✔️Correct Ans-technologist
Pixel malfunction within a DR image receptor is likely to manifest on a radiograph as: ✔️Correct
Ans-hyperdense artifact
Which term best describes the process of adding brightness and contrast to exposure values
within a radiographic image? ✔️Correct Ans-lookup table (LUT) conversion
The appearance of quantum mottle on a radiograph is caused by: ✔️Correct Ans-inadequate
receptor exposure
If a radiograph demonstrates an "S" (sensitivity) number of 80 with no visible exposure errors,
the technologist should consider which of the following actions? ✔️Correct Ans-submit the
radiograph as-is without repeating the exposure
Which of the following information is required to be included in Digital Imaging and
Communication in Medicine (DICOM) images? ✔️Correct Ans-exam location (facility)
, A technologist is using a variable kVp chart to set the exposure technique for a table-top
radiograph. If the technique chart calls for 76 kVp but the technologists uses 140 kVp, the
resulting image will likely demonstrate which of the following? ✔️Correct Ans-saturation artifact
When reviewing the radiographic exposure indicator, what does an "S" (sensitivity) number
significantly below 200 indicate? ✔️Correct Ans-excessive receptor exposure
Which two of the following identifiers are required by law to included on a radiographic image?
(select two) ✔️Correct Ans-location of the examination
right or left marker
Which technologist mistake is most likely to cause processing error within a computed
radiography (CR) system? ✔️Correct Ans-asymmetrical collimation
How is patient information added to a digital x-ray image? ✔️Correct Ans-digital imaging and
communication in medicine (DICOM) tag
A technologist accidentally processes a chest radiograph under the abdomen histogram protocol.
How should this mistake be corrected? ✔️Correct Ans-reprocess the raw data using the correct
hisogram protocol
A technologist is using a variable mAs chart to set the exposure technique for a portable
radiograph. If the technique chart calls for 12 mAs but the technologist uses 1.5 mAs, the
resulting image will likely demonstrate which of the following? ✔️Correct Ans-quantum mottle
