Wow
This approach to patient care involves treating the whole person rather than just the specific area of interest.
What is a holistic approach?
These two nonverbal tools, along with verbal messages, are essential for effective communication between a radiographer and a patient.
What are body language and clear, concise instructions?
Providing thorough explanations of procedures helps alleviate this, which patients often feel when facing the unknown.
What is anxiety or fear?
This type of motion can normally be willfully controlled by the patient, though factors like age or anxiety may interfere.
What is voluntary motion?
To compensate for involuntary motion, a radiographer can decrease this technical factor while increasing milliamperes.
What is exposure time?
Chills, muscle spasms, and tremors from Parkinson’s disease are all clinical manifestations of this type of motion.
What is involuntary motion?
This committee was formed to educate the profession regarding the AAPM position statement on gonadal shielding.
What is the CARES Committee (Communicating Advances in Radiation Education for Shielding)?
This term refers to the graininess or noise in an image caused by too few x-rays reaching the image receptor.
What is quantum mottle (or quantum noise)?
Imaging departments use these to ensure uniform selection of exposure factors when a calibrated AEC system is not used.
What are standardized technique charts?
This noninvasive x-ray procedure is the most widely used test to measure bone mineral density
What is a DEXA (or DXA scan)?
These three areas of the body should be shielded from the useful beam whenever possible due to their radiosensitivity.
What are the lens of the eye, breasts, and thyroid gland?
*also accept reproductive organs instead of breasts*
To ensure a high-quality image, a radiographer seeks the maximum amount of this and a minimal amount of distortion
What is spatial resolution?
This scientific consensus states that all dose levels of ionizing radiation have a potential for producing detrimental effects
What is the linear non-threshold concept?
According to the US Public Health Service, the estimated GSD for the United States population is approximately this value
What is 0.20 millisievert (20 mrem)?
This concept is used to assess the impact of a gonadal dose on an entire populace
What is the genetically significant dose (GSD)?
Due to anatomic location, the female reproductive organs receive about this many times more exposure during pelvic procedures than male organs
Question: What is three times?
Because it contains large numbers of stem cells, the dose to this area is significant due to the risk of inducing leukemia
What is bone marrow?
These sensing devices, which contain lithium fluoride, are most often used to directly determine skin dose
What are thermoluminescent dosimeters (TLDs)?
Of the three ways to specify patient amount of radiation, this one is the most frequently reported because it is the simplest to determine
What is Entrance Skin Exposure (ESE)?
This technique is an alternative to using a radiographic grid and works by increasing the object-to-image receptor distance (OID)
What is the air gap technique?
While film-based repeat rates were often due to technical factors, the primary cause for repeated images in digital departments has shifted to this
What are positioning errors?
The ASRT considers the routine use of fluoroscopy to ensure proper positioning before an exposure to be this kind of practice
What is unethical?
This method of positioning, which relies on the radiographer's skill and anatomic landmarks, provides the patient with the lowest dose
What is blind positioning?
The air gap technique is generally not as effective when using kilovoltage (kVp) settings at or above this level
What is 90 kVp?
This type of program is indispensable for every imaging department to ensure regular monitoring and maintenance of processing and display equipment
What is a quality control (QC) program?
