|---|---|---|---|---|---|
| show | Tungsten filament, negative charge, static (not moving)
🗑
|
||||
| show | kVp and applying voltage (voltage = velocity = acceleration
🗑
|
||||
| show | Straight path from the focusing cup to the anode, reflection angle = incident angle
🗑
|
||||
| 4. What part of the radiographic tube is responsible for deceleration of electrons. | show 🗑
|
||||
| 5. List and describe the two target interactions and what they produce. | show 🗑
|
||||
| show | Inversely proportionate, higher the frequency the smaller the wavelength and vise versa.
🗑
|
||||
| show | KVP and produces contrast (kVp=quality=contrast=image brightness)
🗑
|
||||
| show | mA and time (level of doness, heat & time)
🗑
|
||||
| 9. Please describe the interaction or effects that produce the radiographic image. | show 🗑
|
||||
| show | distance & intensity
🗑
|
||||
| show | Travel in straight paths; invisible; rays are divergent, ionize matter, high frequency
🗑
|
||||
| 12. Besides the photoelectric effect, name and describe 2 other photon interactions. | show 🗑
|
||||
| show | Decrease of energy. 3 factors: absorption, scatter, reflection. Absorption is dominant factor.
🗑
|
||||
| show | Controls for mA, kVp (major & minor), line control, AEC, meters, backup timer
🗑
|
||||
| show | High heat storage capacitor, high heat dissipator, and high atomic number
🗑
|
||||
| 16. List at least 2 types of collimators. | show 🗑
|
||||
| show | kVp, ma & time, filtration, distance (SID, OID)
🗑
|
||||
| 18. The x-ray tube needs what type of current? | show 🗑
|
||||
| 19. What part of the x-ray circuit provides the direct current to x-ray tube? | show 🗑
|
||||
| 20. Please provide your instructor with a basic explanation of the production of the x-ray beam, not the radiographic image. (hint: do not include what happens to the patient) | show 🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
