The technique shown in this image is known as what?

The bisecting-angle technique
The mandible technique
The maxiallry technique
The parallel technique

Correct Answer

A. The parallel technique

Explanation

The image shows a dental X-ray with the X-ray beam directed perpendicular to the teeth and the film. This technique is known as the parallel technique, where the X-ray beam and the image receptor are positioned parallel to each other, resulting in a more accurate and consistent image. The other options, such as the bisecting-angle technique, mandible technique, and maxillary technique, do not accurately describe the technique shown in the image.

Absorbed dose is the energy deposited in a small volume of matter (tissue) by the radiation beam passing through the matter divided by the mass of the matter. What unit, in the International System of quantities and units, is Absorbed Dose measured in?

The gray
The rad
The sievert
The joule

Correct Answer

A. The gray

Explanation

Absorbed dose is measured in joules/kilogram, and a quantity of 1 joule/kilogram has the special unit of gray (Gy) in the International System of quantities and units. (In terms of the older system of radiation quantities and units previously used, 1 Gy equals 100 rad, or 1mGy equals 0.1 rad.)

Also an active ingredient in enemas, _____ compounds are used in pyrotechnics, petroleum mining and radiology?

Correct Answer
barium

Explanation
Barium compounds are commonly used in various industries. In pyrotechnics, barium compounds are used to produce green-colored fireworks. In petroleum mining, barium compounds are used as drilling mud additives to increase the density of the mud and control well pressure. In radiology, barium compounds are used as contrast agents in X-ray examinations to enhance visibility of the gastrointestinal tract. Additionally, barium compounds are also used as an active ingredient in enemas to help diagnose and treat certain medical conditions. Overall, barium compounds have diverse applications in different fields.

Which diagnostic scan gives some of the highest radiation doses in diagnostic radiography?

CT scan
Ultrasound scan
MRI scan
Flouroscopy scan

Correct Answer

A. CT scan

Explanation

CT scans, or computed tomography scans, involve the use of X-rays to produce detailed cross-sectional images of the body. Due to the nature of this imaging technique, CT scans often result in higher radiation doses compared to other diagnostic radiography procedures. This is because CT scans require multiple X-ray beams to capture images from different angles, resulting in a higher radiation exposure for the patient. Ultrasound scans, MRI scans, and fluoroscopy scans do not involve the use of ionizing radiation and therefore do not pose the same radiation risks as CT scans.

Where on a dog are the retroarticular foramen and hypoglossal canal located?

Leg
Skull
Spine
Pelvis

Correct Answer

A. Skull

Explanation

The retroarticular foramen and hypoglossal canal are located on the skull of a dog. These structures are important for the passage of nerves and blood vessels. The retroarticular foramen is a small opening located behind the jaw joint, through which the hypoglossal nerve passes. The hypoglossal canal is a canal in the base of the skull that also allows for the passage of the hypoglossal nerve. Both of these structures are specific to the skull and are not found on the leg, spine, or pelvis.

X-rays are produced when fast moving electrons collide with a metal target. The energy carried in the electrons is converted to x-rays and heat. What percentage of that energy is turned into x-rays?

1%
35%
70%
99%

Correct Answer

A. 1%

Explanation

When fast moving electrons collide with a metal target, the energy they carry is converted into both x-rays and heat. The given answer states that only 1% of the energy is turned into x-rays, indicating that the majority of the energy is converted into heat.

Some veterinary DR x-ray camera systems can lose image quality fairly quickly. The image quality of these CCD (Charged Coupled Device) digital x-ray systems is effected over time by all of the following EXCEPT...

Moving parts
Condensation
Room lighting
Temperature

Correct Answer

A. Room lighting

Explanation

The image quality of veterinary DR x-ray camera systems can deteriorate over time due to various factors. Moving parts, condensation, and temperature can all have an impact on the image quality of CCD digital x-ray systems. However, room lighting does not affect the image quality of these systems.

X rays were discovered in 1895 by W. C. Roentgen, who called them X rays because their nature was at first unknown; they are sometimes also called Roentgen, or Röntgen, rays.
