Review: Basic X-Ray Machine
Operator Certification
What are the Characteristics of x-rays?
1. Don't have any mass
2. Are electrically impartial
3. Tour in instantly lines
4. X-rays produce biologic adjustments in tissues
five. X-rays are a shape of electromagnetic electricity
The agency that sets requirements and prepares examinations essential to certify radiologic
technologists and restricted operators is the:
American Registry of Radiologic Technologists (ARRT)
The radiation that exits the alternative side of the patient to reveal the photograph receptor (IR)
is referred to as?
Remnant radiation
The time period used to explain radiation this is absorbed by using be counted is:
Attenuation
The "unseen" photo this is contained in the picture receptor (IR) before it's miles processed is
known as the:
Latent photo
The radiation that exits the body in all directions and causes undesirable publicity at the photo
receptor (IR) as well as all and sundry who's within the room is referred to as __________
radiation.
,Scattered
The radiation that exits the x-ray tube and travels in-air to the patient is called:
Primary
The oldest and biggest radiologic technology professional corporation is the:
American Society of Radiologic Technologists (ASRT)
The boxlike device connected underneath the tube housing that lets in the operator to differ the
dimensions of the radiation field is called the:
Collimator
An invisible line in the center of the x-ray beam and perpendicular to the lengthy axis of the
x-ray tube is called the:
Central Ray
An publicity time of 0.02 seconds is identical to what number of milliseconds?
20 ms
When 62 kVp is increased by means of 30%, the result is approximately:
eighty one
When the fraction 7/eight is transformed to a decimal, the end result is:
0.875
A radiographic photograph is made using 500 mA, 0.1 sec., eighty kVp, and
48-inches SID. The cost of the mAs for this exposure is
50 mAs
X-rays have electromagnetic power. The speed (or speed) of this energy travels at a speed of:
, 186,000 miles according to 2nd
The smallest feasible unit of electromagnetic strength is the:
Photon
The electric current flowing in an x-ray tube is measured in:
Milliamperes (mA)
The pressure or energy of the electron float in an electrical contemporary is measured in:
Kilovoltage (kVp)
The tool used to supply the high voltage wished for x-ray production is known as the:
Transformer
In radiology, eighty,000 volts is converted to:
(normally used unit)
80 kVp
The goal and the filament in the x-ray tube are manufactured from:
Tungsten
Electrons are made available in the filament of the x-ray tube by a technique known as:
Thermionic emission
The anode within the x-ray tube rotates at a high RPM for what reason:
