| 2. How is Bremsstrahlung radiation produced? | show 🗑
|
||||
| show | electron speeds close the inner orbit electrons and high quality energy is released
🗑
|
||||
| 4. What type of radiation is x-radiation? | show 🗑
|
||||
| show | speed of light; 186,000 miles per second
🗑
|
||||
| 6. List the characteristics and properties of x-radiation. | show 🗑
|

| 7. What can be done to increase the amount of x-radiation emitted from the machine? | show 🗑
|
||||
| show | increase kVp
🗑
|

| 9. How will the radiograph be affected if the mA is decreased? | show 🗑
|
||||
| show | lower contrast (longer gray scale); darker - higher in density
🗑

| 11. How will the radiograph be affected if the mA is increased? | show 🗑
|
||||
| 12. How will the radiograph be affected if the kVp is decreased? | show 🗑

| 18. What quality of the x-ray is changed when the wavelength is changed? | show 🗑
|
||||
| 19. What type of collimator is recommended by the ADA? | show 🗑
|
||||
| show | intensity of the x-ray beam decreases inversely proportional to the square of the distance from the source (as the beam gets farther from the tube, it gets larger AND less concentrated)
🗑
|
||||
| show | higher contrast radiograph with fewer shades of gray evident
🗑
|

|
||||
| show | turn it off
🗑
|
||||
| show | move the tubehead into various postions and see if it remains or drifts
🗑
|
||||
| show | have it repaired; in the meantime, do not use it
