At the hip, the femoral head articulates with a socket formed by which three bony components?
Correct answer: C - Ilium, ischium, and pubis
An abdominal radiograph is acquired with the patient lying face up. The beam travels horizontally from the patient's right side to a detector beside the left side. How should the position and projection be described?
Correct answer: A - Supine position with a lateral projection
A newly terminated 100BASE-TX cable passes a pin-to-pin continuity check, but image transfers produce network errors. At both plugs, pins 1, 2, 3, and 6 are wired white/orange, green, white/green, and orange, respectively. What defect did the continuity check miss?
Correct answer: B - Split pair
A modality has received successful C-STORE responses for an entire study. Before deleting its local copy, the site requires the archive to accept responsibility for retaining those images and making them retrievable for its documented retention period. What additional DICOM confirmation is needed?
Correct answer: A - Successful Storage Commitment covering every image
An ultrasound display plots tissue depth vertically and elapsed time horizontally. Bright traces track structures intersected by one fixed beam. This display represents:
Correct answer: D - M-mode acquisition
During pediatric radiography optimization, the imaging team wants to shorten a 200 mA, 50 ms manual exposure to 20 ms while preserving mAs. At the selected kVp and proposed exposure duration, the tube-loading chart permits up to 300 mA on the small focal spot and 600 mA on the large focal spot. Which setting satisfies both the exposure target and the tube limit?
Correct answer: D - 500 mA for 20 ms, using the large focal spot
A narrow-beam x-ray quality check at 80 kVp gives 120 microgray without added aluminum and 60 microgray with 3.0 mm Al. When mAs is doubled, the readings become 240 and 120 microgray, respectively. The kVp, existing filtration, and measurement geometry are unchanged. What should the technician report?
Correct answer: C - The first HVL is unchanged at 3.0 mm Al
Daily CT images of a uniform water phantom show a thin dark circle centered on the scanner's rotation axis. Repositioning the phantom moves its outline, but the circle stays centered on that axis. The most appropriate initial corrective step is to:
Correct answer: B - Run manufacturer-prescribed detector air calibration, then repeat the image
During testing of a fluoroscope with x-ray controls manufactured in 2022, an audible signal sounds at five minutes of accumulated irradiation and resets automatically after three seconds. Irradiation continues while the pedal is held and stops when it is released. A service note calls this a failure of the five-minute beam cutoff. How should that finding be resolved under 21 CFR 1020.32(h)?
Correct answer: B - Correct the note: the five-minute signal need not stop irradiation.
An oxygen-deficiency alarm sounds during service of a superconducting MRI magnet, and a cloud of cold vapor appears in the scanner room. Everyone inside can leave without assistance. What takes priority?
Correct answer: A - Evacuate the room, restrict access, and activate the emergency response
