- If using both blue and green sensitive films what type of safe light should you use
Answer: Red 1 / 3
- The main purpose of the x-ray developer is to
Answer: Convert the exposed silver halide crystals to black metallic silver
- The main purpose of the x-ray fixer is
Answer: Clear away the unexposed undeveloped silver halide crystals
- A safe light illumination test was performed in the dark room. On processing the film you
see various gradations of blackness on your film the area exposed for the longest amount of time is
Answer: Darkest
- After you manually process of film you notice there's a green area about half inch along
the narrow edge of the film this is due to the area not being
Answer: - Developed or fixed
- you notice there's a clear line at the top of the shortage of the radiograph that you have
manually process. This is due to the area not
Answer: Being developed
- You're looking at a film that is totally clear except for a bit of black that you notice along the
edges. Your film has not been
Answer: Exposed to radiation
- A sievert (Sv) is the
Answer: Unit of radiation dose equivalent to the absorbed dose in tissue
- You are preparing to take radiograph and want to set the correct mAs of
- Which of the following will give you 15 mAs?
- 300 mA 1/10 sec
- 300 mA 1/20 sec
- 150 mA 1/15 sec
- 150 mA 1/20 sec
Answer: 300 mA 1/20 sec
- If you were going to decrease the focal film distance from 100 centimeters to 50
centimeters what would your new mAs if the old mAs was 16
Answer: 4 mAs
- Scatter radiation on a film is more noticeable if there is
Answer: Higher kVp thicker patient and larger field size
- Because of the relationship between milliamp and MAS as you increase the MA you can
- Decrease the length of exposure so that there's less chance of movement 2 / 3
- Decrease the length of exposure so that there is more chance of movement
- Increase the length of exposure so that there is more chance of movement
- Increase the kVp which means no change in density
Answer: A. Decrease the length of exposure so that there is less chance of movement
- The crystals of high-speed screens as compare to similar types of par screens are
Answer: Bigger and there is less detail
- The main advantage of fast speed screens and films is that
Answer: Lower exposure factors can be used which can allow use of smaller focal spot
- If you are looking at a radiograph it appears gray overall this is best described as a
Answer: Low contrast film with many steps but few changes between each step
- Grid cut off can best be described
Answer: Incorrect use of the grid so that the grid absorbs more radiation than it should
- A radiograph in front of you appears dark. You note that the bones are gray. You are best to
do what for the next radiograph?
Answer: Decrease kVp
- You want to set up an abdominal radiographic technique chart. All of the following factors
- Whether to use a grid
- The film type used
- Focal film distance
- The kVp used
should be standardized accept
Answer: The kVp used
- A dog is laying in left lateral recumbency for pelvis radiograph. The right femur will be
Answer: More magnified because of decreased focal film distance and in- creased object film distance
- The term dorsomedial plantarolateral oblique means that the xray beam is directed at the
Answer: Dorsal limb aspect in the film is against the lateral side of the limb
- The best view of the elbow
Answer: Craniocaudal
- The best view for tympanic bulla is
Answer: Open mouth rostro-caudal
