Introduction
The medical practice of using ionizing radiation to diagnose patients
What is radiology?
What is Compton scatter?
The reduction of low energy photons in the x-ray beam and a decrease to patient dose.
What is filtration?
A friend or family member of the patient who isn't pregnant and is at least 18 y/o.
Who should hold a patient during the radiograph?
An indicator of the radiation absorbed by the IP
What is the exposure indicator/index?
The single most effective means of reducing radiation exposure.
What is distance?
The interaction with inner shell electrons and ionizing radiation.
What is the photoelectric effect?
Effects of radiation that appear in the irradiated individual.
What are somatic effects?
Primary source of radiation exposure for occupational personnel. This means you.
What is compton scatter?
The unsharpness of the edges in a radiographic image.
What is penumbra?
What is tungsten?
The naturally occurring phenomenon that allows for air fluid level visualization in imaging.
What is gravity?
The most common source of patient protection found within all radiology suites.
What is the lead apron?
The unit of radiation absorbed dose.
What is the rad/gray?
Image distortion that is always present due to the distances between anatomy and the IR.
What is magnification?
The scientist credited for the discovery of radiation and won a Nobel prize.
Who is Roentgen?
When x-ray photons reduce in numbers, lose energy, and produce ionization.
What is attenuation?
Intensity equals the inverse of the square of the distance from the source
What is the inverse square law?
The motto and acronym for the reduction of unnecessary radiation exposure in the clinical setting.
What is ALARA(as low as reasonably achievable)?
A device placed between the patient and the cassette to improve image quality.
What is a grid?
A modality in medical imaging that is a combination of Nuclear medicine and CT/MRI.
What is positron emission tomography or PET CT/MRI?
Matter found in the human body that has the least attenuation of the x-ray beam.
Name and date of birth.
What is the two factor authentication for patient exams?
Daily double!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
