Answers
All hard copies of radiographs, computed tomography (CT) scans, ultrasound images, and magnetic
resonance imaging (MRI) studies are:
the hospital's property and part of the patient's record
For a radiograph to be considered admissible as evidence in a court of law, at least the _____ must be
permanently imprinted onto it prior to developing.
Patient name or identification number, owner name, hospital name, and date of the examination
The term radiographic technique generally refers to:
The machine's exposure settings (e.g., kVP, mAs) during a given examination
X-rays cannot penetrate:
Lead
Concerning the filaments in the x-ray tube that produce electrons, which statement is most accurate?
The small filament may melt more rapidly than the large filament if an excess load is placed on it.
Why are rotating-anode x-ray machines more powerful than stationary-cathode x-ray machines?
- The former allow greater dissipation of heat.
- The former allow the use of a smaller focal spot with higher tube currents.
- The former allow the use of shorter exposure times.
(all answers are correct)
The primary source of radiation exposure to the technician during radiography is scattered radiation,
which can best be defined as:
Lower-energy x-ray photons that have undergone a change in direction after interacting with
structures in the patient's body
The acronym kVP stands for _____ and controls the _____ of x-ray photons produced.
Kilovolt peak; speed
You have just taken a thoracic radiograph at 50 kVP and 100 mA at 1/10 second. The pet's breathing
caused his chest to move during the exposure, resulting in a blurry image. On the retake, how can you
correct for this motion to create a clear image of the same density?
Reduce the time to 1/20 second and increase the mA to 200.
You have radiographed a fractured femur in a large dog. The resulting image is too gray; that is, you
can see many shades of gray and a lot of detail in the muscle layers, but the bone is also too gray, and
bony fragments are difficult to see. How can you best correct your settings to create a clearer image
of the fractured bone?
Decrease the kVP.
, Which statement is most accurate concerning the effects of a change in focus-film distance (FFD)
when taking radiographs?
The mAs setting must be changed according to a standard mathematical formula.
How does one obtain the correct machine settings when taking a radiograph?
Settings are obtained from a "technique chart" created, by trial and error, specifically for the machine
one is using.
Concerning the use of film holders (cassettes) in veterinary radiography, which statement is most
accurate?
A "nonscreen" cassette is made of nonrigid cardboard or plastic and The most commonly used
cassettes in companion-animal practice are rigid and contain an image-intensifying screen.
Care of image-intensifying screens involves:
Cleaning them with a special solution or 70% isopropyl alcohol at least once monthly or whenever
screen artifacts are seen on a radiograph
The purpose of a grid is to:
Allow only the primary x-ray beam to pass through and prevent scattered radiation from reaching the
film and Increase the resolution of thicker body parts.
Most mistakes made in veterinary radiography are related to:
Improper processing techniques
Which statement concerning hand processing versus automatic-film processing of radiographs is most
accurate?
Both techniques require the use of fresh solutions and a well-ventilated darkroom.
X-ray film recycling and special units attached to fixer tanks allow the recovery of _____, a valuable
and reusable substance.
Silver
After exposing and developing an x-ray, you find the film totally white. What is the most likely cause
of this problem?
The film is unexposed.
In a practice using automatic x-ray processing equipment, the veterinary technician is expected to
Keep the processor clean and add fresh developer and fixer solutions as needed.
What is necessary to prevent "fogging," or partial exposure, of x-ray film in the darkroom?
- Absolutely no light leakage into the room
- A lock on the door to prevent entrance during film processing
- A safelight of correct wattage and filter type for the film used
