Intro to Diagnostic Imaging
This is the electrical charge of the anode.
What is positive?
This is the primary source of radiation exposure for personnel manually restraining patients.
What is scatter radiation?
This is the lead marker you would use when taking a right lateral radiograph.
What is 'R' (or right)?
This setting affects image contrast.
What is kVp
This is the radioisotope used to identify bone pathology via nuclear scintigraphy.
What is Technitium-99m?
This is where the focal spot is located within the x-ray tube.
What is the anode?
This is the term for the x-ray photons that have undergone a change in direction after interacting with an object.
What is scatter radiation?
This is the cranial collimation border for thoracic radiographs.
What is the shoulder joint (or point of the shoulder)?
(Blank) contrast is preferred for radiographs of extremeties.
What is high contrast?
This fluoroscopy setting reduces patient radiation dose and heat accumulation while still providing real time, dynamic images.
What is pulse?
This is the percentage of energy that exits the x-ray tube in the form of heat.
What is 99 percent?
This is the part of the cell most vulnerable to damage by ionizing radiation.
What is DNA?
This radiographic view is ideal for visualizing the heart.
What is dorsoventral?
Tighter (blank) reduces scatter radiation and patient dose, and improves image quality.
What is collimation?
Fluorodeoxyglucose is the radioisotope used to assess brain activity and identify malignant tumors in this specialized imaging modality.
What is positron emission tomography (or PET)?
Within the x-ray tube, the electrical current must travel in one direction from the (blank) to the (blank).
What is the cathode to the anode?
This is the term for the ability of radiation to transfer energy into tissue.
What is linear energy transfer?
When viewing a lateral radiographic image, this end of the animal should be on the left side of the monitor screen.
What is the cranial end?
This is the artifact that can occur when the x-ray beam is not perpendicular to the area of interest.
What is distortion?
This variation within an atom's nucleus determines its isotope.
What is the number of neutrons?
This is what happens during activation of the first stage of a dual-stage exposure switch.
What is activation of the anode rotor (and heating of the cathode filament)?
This term describes how radiation dose decreases with distance in a nonlinear way.
What is the inverse square law?
What is the bottom leg?
The maximum energy of the x-ray photons within the x-ray beam is determined by this setting.
What is kVp?
What is upper GI contrast study?
