What are the Characteristics of x-rays? 1. have no mass
2. are electrically neutral
3. travel in straight lines
4. X-rays produce biologic changes in tissues
5. X-rays are a form of electromagnetic energy
The organization that sets standards and prepares American Registry of Radiologic Technologists (ARRT)
examinations necessary to certify radiologic
technologists and limited operators is the:
The radiation that exits the opposite side of the patient to Remnant radiation
expose the image receptor (IR) is called?
The term used to describe radiation that is absorbed by Attenuation
matter is:
The "unseen" image that is contained in the image Latent image
receptor (IR) before it is processed is called the:
The radiation that exits the body in all directions and Scattered
causes unwanted exposure on the image receptor (IR) as
well as anyone who is in the room is called __________
radiation.
The radiation that exits the x-ray tube and travels in-air to Primary
the patient is called:
The oldest and largest radiologic science professional American Society of Radiologic Technologists (ASRT)
organization is the:
, The boxlike device attached under the tube housing that Collimator
allows the operator to vary the size of the radiation field is
called the:
An invisible line in the center of the x-ray beam and Central Ray
perpendicular to the long axis of the x-ray tube is called
the:
An exposure time of 0.02 seconds is equal to how many 20 ms
milliseconds?
When 62 kVp is increased by 30%, the result is 81
approximately:
When the fraction 7/8 is converted to a decimal, the result 0.875
is:
A radiographic image is made using 500 mA, 0.1 sec., 80 50 mAs
kVp, and
48-inches SID. The value of the mAs for this exposure is
X-rays have electromagnetic energy. The velocity (or 186,000 miles per second
speed) of this energy travels at a speed of:
The smallest possible unit of electromagnetic energy is Photon
the:
The electrical current flowing in an x-ray tube is Milliamperes (mA)
measured in:
The force or strength of the electron flow in an electrical Kilovoltage (kVp)
current is measured in:
The device used to produce the high voltage needed for Transformer
x-ray production is called the:
In radiology, 80,000 volts is converted to: 80 kVp
(commonly used unit)
The target and the filament in the x-ray tube are made of: Tungsten
Electrons are made available in the filament of the x-ray Thermionic emission
tube by a process called:
The anode in the x-ray tube rotates at a high RPM for Dissipate the heat
what reason:
The target in the x-ray tube is angled to affect the: heat capacity
sharpness of the image
