QuestionAnswer
SI quantity that can be used to specify the amount of radiation transferred to a point at the surface of a patient’s or radiographer body? Air kerma
The energy of incident photon is completely absorbed during of which interactions with matter? Photoelectric absorption
A correct regarding the relationship between pixel size, pixel pitch, and spatial resolution? As pixel decreases, pixel pitch decreases, spatial resolution increases
Is responsible for correcting the brightness and contrast of an image, regardless of the technique used? Rescaling
Two functions of correcting data for processings? Edge enhancement and smoothing
The safe approach to avoid an exposure field recognition error when using CR is to: Expose one image on the smallest IP available with collimation margins aligned parallel to the edge of the IP.
Is responsible for producing the diagnostic portion of the image on the image receptor? Remnant
There are several types of DR image receptors used in digital imaging. All use indirect capture except: Amorphous selenium flat panel detectors
Are associated with hight frequencies and short wavelengths: X-rays and gamma rays
Processing functions increases the sharpness of the details in an image: Edge enhancement
When positioning for a lateral larynx and airway projection, where should the CR enter if the area of interest is the distal larynx and trachea: T 1-2 (jugular notch)
The distance from the side of one pixel to the opposite side of that same pixel? Pixel size
Element of the transmission cycle of infection is a person with chronic disease such as diabetes mellitus? A susceptible host
Grids used in radiography, describes the relationship of the lead lines being parallel or angled to each other: Grid focus
Cells that least radiosensitive: Myocytes
The division process of genetic cells is termed: Meiosis
Produces a potential difference within the x-ray tube during an exposure? kVp
Types of compensating filters would primarily be used for shoulder images? Boomerang filters
May occur if a high-pass filtering is used on an image with high contrast? Excess noise
Less than 12 breath per minutes indicates? Bradypnea
More than 20 breath per minutes indicates? Tachypnea
A condition resulting from chest trauma by motor vehicle accident or falling which the pleural spaces filled with air, is called: Pneumothorax
Personnel dose is increased during which examinations: Fluoroscopy and mobile imaging
Compared to centering for the lateral cervical spine, centering for the lateral upper airway is? Lower and more anterior
Without any changing any other factors, which best describes the impact on the final image when SID is increased? Image receptor exposure decrease, spatial resolution increases
Factors that is the only thing affected by changing the focal spot size? Spatial resolution
Focal spot size decreases? Spatial resolution increases
Will result if OID increases: Size distortion
An individual legal documents identifying his or her specific wishes regarding medical care to provided in the event that he or she is unable to make or communicate decision is called: Advance Health care directive
If a patient lacks decision making capacity, his or her rights can be exercised on his or behalf by: Designated surrogate, designated proxy
Will help to reduce patient dose: Tube filtration, proper beam alignment, AEC
Pathologic conditions are considered additive conditions with respect selecti
