Study Resource Test Bank - Complete Verified Answer Set The oldest and largest radiologic science professional organization is the: - American Registry of Radiologic Technologists (ARRT) - American Society of Radiologic Technologists (ASRT) - Joint Review Committee on Education in Radiologic Technology (JRCERT) - American Hospital Radiology Administrators (AHRA) - answer - American Society of Radiologic Technologists (ASRT) The organization that sets standards and prepares examinations necessary to certify radiologic technologists and limited operators is the: - American Registry of Radiologic Technologists (ARRT) - American Society of Radiologic Technologists (ASRT) - Joint Review Committee on Education in Radiologic Technology (JRCERT) - American Hospital Radiology Administrators (AHRA) - answer - American Registry of Radiologic Technologists (ARRT) An invisible line in the center of the X-Ray beam and perpendicular to the long axis of the X-Ray tube is called the: - radiation field - primary X-Ray beam - X-Ray tube - central ray - answer - central ray The boxlike device attached under the tube housing that allows the limited operator to vary the size of the radiation field is called the: - port - detent - housing - collimator - answer - collimator The radiation that exits the body in all directions and causes unwanted exposure on the image receptor (IR) as well as anyone who is in the room is called: - remnant radiation - scattered radiation - secondary radiation - primary radiation - answer - scattered radiation The radiation that exits the opposite side of the patient to expose the image receptor (IR) is called: - attenuated radiation - scatter radiation - primary radiation - remnant radiation - answer - remnant radiation The radiation that exits the X-Ray tube and travels in-air to the patient is called: - primary - remnant - scatter - latent - answer - primary The term used to describe radiation that is absorbed by matter is: - scatter - attenuation - remnant - latent - answer - attenuation The "unseen" image that is contained in the image receptor (IR) before it is processed is called the: - latent image - remnant image - primary image - secondary image - answer - latent image In radiology, 80,000 volts is converted to: - 0.125 volts - 125 volts - 80 kVp - 800 kVp - answer - 80 kVp The device used to produce the high voltage needed for X-Ray production is called the: - diode - generator - transformer - rectifier - answer - transformer The electrical current flowing in an X-Ray tube is measured in: - milliamperes - kilovoltage - Ohms - resistence - answer - milliamperes The force or strength of the electron flow in an electrical current is measured in: - milliamperes - kilovoltage - Ohms - resistence - answer - kilovoltage The smallest possible unit of electromagnetic energy is the: - proton - neutron - electron - photon - answer - photon Which of the following would be considered a characteristic of X-Rays? 1. have no mass 2. are electrically neutral 3. travel in straight liones - 1 and 2 - 1 and 3 - 2 and 3 - 1, 2, and 3 - answer - 1, 2, and 3 X-Rays have electromagnetic energy. The velocity (or speed) of this energy travels at a speed of: - 186,000 meters per second - 200,000 meters per second - 186,000 miles per second - 200,000 miles per second - answer - 186,000 miles per second Electrons are made available in the filament of the X-Ray tube by a process called: - heterogeneous - characteristic production - bremsstrahlung production - thermionic emission - answer - thermionic emission If the mA is doubled, the x-ray photons emitted from the tube: - double - triple - increase by a factor of 4 - remain the same - answer - double The anode in X-Ray tubes rotates at a high rpm to: - dissipate the heat - create more photons - create heterogenous beam - allow more bremsstrahlung to be emitted - answer - dissipate the heat The density in the radiographic image is primarily controlled by the: - mA -
