X-ray Circuits Matching
| why can you only obtain mAs meter readings immediately after an exposure? |
| tube current is only generated during the second phase of the x-ray production process |
| this meter measures the current passing between the electrodes of an x-ray tube |
| millammeter-seconds meter |
| reduction of voltage and development of high amperage by a step down transformer occurs in the |
| filament portion of the circuit |
| why are the majority of the components of the x-ray tube found in the primary circuit? |
| reduce the risk from electrical shock |
| most common device used to create the high potential difference across the x-ray tube |
| in a radiographic unit, the milliammeter will register only during the activation of the |
| second (exposure) stage of the exposure switch |
| large focal spot is used for settings above what mA? |
| the high temps that are needed to produce the thermionic emission in the filament of an x-ray tube require a current of about: |
| 4-6 amps (temp of 2200 degrees celcius) |
| an increase in kVp will also cause an increase in _____________ that requires the use of a _________________. |
| electron cloud, space charge compensator |
| which circuit? 25,000-150,000 volts |
0:00
