| Question | answer |
|---|
| xrays make radiographic film _____ (color) | |
| what metal is the focusing cup made of | |
| number of wave cycles that pass a stationary point in a second | |
| optimal developer temp is __ degrees F | |
| a ______ transformer reduces incoming line current from amperes down to mA, called the 'low voltage' circuit | |
| (small/large) focal spots are desired because they result in very clear images | |
| what metal is the filament made of? | |
| T or F: there is no limit to how small a focal spot can be | |
| type of anode with limited ability to withstand heat generated by electrons hitting the target | |
| difference in density and mass between two adjacent anatomic structures | |
| number of protons is (greater, equal, less) number of electrons | |
| this surrounds anode/cathode, creates a vacuum so no air molecules are present | |
| density difference between two adjacent areas on a radiograph | |
| T or F: silver should be disposed of by washing down the drain | |
| what is the viewing contrast desirable for soft tissues (high, low) | |
| The _____ effect is where the intensity of the beam varies and is stronger on the cathode side due to the angle of the target | |
| _______ allow flow of electrons in one direction only | |
| fixer pH is | |
| the kVp selector is also called ___________ | |
| the primary machine setting controlling depth of penetration | |
| thicker parts absorb (more/less) xrays and make film (darker/lighter) | |
| As the focal spot becomes larger, the image becomes fuzzy and less clear; this is called the _______ effect | |
| radiographer can switch filaments by turning the ___ selector | |
| distance between two consecutive corresponding points on a wave | |
| type of anode developed to help dissipate the heat generated at the target; can use higher mA's with these | |
| xrays are a form of __________; which are bundles of energy that travel in waves | |
