History or Radiography
The scientist who accidently discovered x-rays.
Who is Wilhelm Roentgen?
The beam that is emitted immediately from the tube, through the tube port.
What is the Primary Beam?
The part of the x-ray beam that goes through the patient completely and will eventually land on the IR.
What is the remnant radiation or beam?
An x-ray taken that the beam first strikes the back side of the patient and then the front before landing on the IR>
What is a PA projection?
The name of the middle (cross hair) of the primary beam.
What is the Central Ray?
The worlds oldest and largest Radiologic Science professional organization.
What is the American Society of Radiologic Technologists?
The part of the x-ray tube that serves as a Tungsten target for the highly charged electrons.
What is the anode?
The type of radiation created when primary beam strikes the patient.
What is scatter radiation?
A type of x-ray projection that just skims the surface of a body type.
What is a tangenial projection?
The amount (percentage) of the energy produced, in the x-ray beam, that is actual x-ray.
What is 1%?
First examples of massive doses of radiation effecting entire populations.
What are the bombings of Hiroshima and Nagasaki?
The tray in the x-ray table or the upright screen that holds the cassette.
What is the Bucky tray?
A variation in intensity of the x-ray beam created because the anode absorbs some of the electrons.
What is the Anode Heal Effect?
A projection where the patient or body part is placed on it's side.
What is a lateral projection?
A type of radiation given off by a charged particle (most often an electron) due to its acceleration caused by an electric field of another charged particle.
What is Bremsstrahlung Radiation?
Discovered Radioactivity and with her husband identified polonium and radium.
Who is Marie Curie?
The part of the x-ray machine that is used to decrease or increase the field of view.
What is the collimator?
The part of the x-ray production that consists of negatively charged particles.
What is the cathode?
The reduce magnification of the heart compared to the lungs.
Why is Chest x-ray taken at 72 SID?
The place the central ray is aligned with when taking a PA projection of the right hand.
What is At the base of the middle or third phalange?
An organization that specializes in the accreditation of programs in Radiography.
What is the JRCERT? (Joint Review Committee on Education in Radiologic Technology)
The positions that lock the x-ray tube at pre-determined positions.
What is detents?
Results in more heat produced, more radiation in the beam and less image quality.
What is Large focal spot?
An x-ray obtained by moving the tube to a position where the central ray is horizontal to the patients.
What is a Decubitus projection?
The number of lead strips per inch.
What is Grid Frequency?
