Chapter 6 Assessment Questions With Accurate Answers

A device between the auto transformer and the high voltage transformer is the primary xay( low voltage)circuit that measures the potential difference across this portion of the circuit is represented on the xray control panel as the correct answer KVp meter A series of warm up exposures is made for the purpose of correct answer Preventing damage to the anode from sudden heating During a quality control check of the exposure timers, the maximum variability is ? For times greater than 10 sec correct answer + - 5 % Exposure times that are as low as .0001 sec and are expressed in decimals (or perhaps in milliseconds or even impulse) are typical of correct answer Electronic timer Exposure times that are as low as 0.001 sec and are expressed in decimals are typical of correct answer Electronic timer Into what three sections(subcircuits) is the xray circuit divied correct answer The low voltage, filament, and high voltage circuit Nearly all new xray machine manufactured today used ? Generators correct answer High-frequency Public Law 90- 602 states that back up trainers in AEC's operating above 50kVp must terminate the exposure at what(maximum) mAs correct answer 600 mAs Public law 90-602 state that generators must terminate the exposure time at what mAs correct answer 600 mAs Some xray control panels are programmable and the exposure factors from the technique chart can be programmed into the generator. This system is called correct answer Anatomically programmed radiography(APR) The function of a rheostat in an xray generator is correct answer Vary the milliamperage
