Questions and CORRECT Answers
Which of the following is used to create the patient's requisition? - CORRECT
ANSWER - Electronic Medical Record (EMR)
Which of the following identifiers are required by law to be included on a radiographic image? -
CORRECT ANSWER - Date of examination
A technologist is using a variable kilovoltage peak(kVp) chart to set the exposure technique for a
table-top radiograph. If the technique chart calls for 87 kVp but the technologst uses 82 kVp, the
resulting image will likely demonstrate which of the following? - CORRECT ANSWER -
no visible errors
The lowest exposure readings on a radiographic histogram usually represent areas of: -
CORRECT ANSWER - Collimated exposure
What information must be physically included in an x-ray image? - CORRECT
ANSWER - right or left marker
Physical damage to the structure of a computed radiography(CR) image receptor(IR) is likely to
manifest on a radiograph as: - CORRECT ANSWER - hyperdense artifact
Which exposure reading is processed as a part of the "values of interest" within a radiographic
image? - CORRECT ANSWER - patient anatomy
What is the process called that converts the original radiographic histogram to the expected
histogram? - CORRECT ANSWER - rescaling
, Processing a radiographic image using the wrong histogram protocol may result in visible errors
such as: - CORRECT ANSWER - incorrect contrast and brightness
A lateral radiograph of the knee demonstrates the superimposition of a femoral condyle over the
joint space. This error can be corrected by adjusting the: - CORRECT ANSWER - x-ray
tube angulation
When reviewing the radiographic exposure indicator, what does an "S" (sensitivity) number
significantly above 200 indicate? - CORRECT ANSWER - insufficient receptor exposure
A technologists recieved a requisition for a two-view knee radiograph, but the technologist
performed a two-view tibia-fibula series. How should this error be corrected? - CORRECT
ANSWER - repeat the examination on the correct body part
When can a technologists reuse the computed radiography (CR) receptor after the appearance of
a ghost image? - CORRECT ANSWER - after it's been thoroughly erased on a functioning
CR reader
Incomplete erasure of a CR image receptor may produce an artifact called: - CORRECT
ANSWER - ghost image
A radiographic histogram is a graphic representation of: - CORRECT ANSWER -
frequency of specific exposure values
Which two of the following identifiers are required by law to be included on a radiographic
image? (select two) - CORRECT ANSWER - patient's name
patient's date of birth
The appearance of saturation artifact on a radiograph is caused by: - CORRECT
ANSWER - excessive receptor exposure
