The BIET exam has 100 questions and runs 2 hours.

These 10 free BIET questions are organized by exam domain, so you can see how each part of the Biomedical Imaging Equipment Technician blueprint is tested. Reveal the answer and explanation under each question.

Domain 1: ANATOMY

Question 1

At the hip, the femoral head articulates with a socket formed by which three bony components?

Show answer & explanation

Correct answer: C - Ilium, ischium, and pubis

Domain 2: MEDICAL TERMINOLOGY

Question 2

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?

Show answer & explanation

Correct answer: A - Supine position with a lateral projection

Domain 3: COMPUTER

Question 3

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?

Show answer & explanation

Correct answer: B - Split pair

Domain 5: PICTURE ARCHIVE COMMUNICATION SYSTEM (PACS)

Question 4

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?

Show answer & explanation

Correct answer: A - Successful Storage Commitment covering every image

Domain 6: DIAGNOSTIC ULTRASOUND (SONOGRAPHY) EQUIPMENT

Question 5

An ultrasound display plots tissue depth vertically and elapsed time horizontally. Bright traces track structures intersected by one fixed beam. This display represents:

Show answer & explanation

Correct answer: D - M-mode acquisition

Domain 8: BASIC RADIOGRAPHIC EQUIPMENT

Question 6

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?

Show answer & explanation

Correct answer: D - 500 mA for 20 ms, using the large focal spot

Domain 10: TEST EQUIPMENT

Question 7

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?

Show answer & explanation

Correct answer: C - The first HVL is unchanged at 3.0 mm Al

Domain 12: COMPUTED TOMOGRAPHY

Question 8

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:

Show answer & explanation

Correct answer: B - Run manufacturer-prescribed detector air calibration, then repeat the image

Domain 14: CODES AND REGULATIONS

Question 9

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)?

Show answer & explanation

Correct answer: B - Correct the note: the five-minute signal need not stop irradiation.

Domain 16: RADIATION SAFETY

Question 10

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?

Show answer & explanation

Correct answer: A - Evacuate the room, restrict access, and activate the emergency response
