|---|---|---|---|---|---|
| show | Tungsten filament, negative charge, static (not moving)
🗑

| 2. In your own words describe the process of electron acceleration. | show 🗑
|
||||
| show | Straight path from the focusing cup to the anode, reflection angle = incident angle
🗑
|
||||
| show | Anode target
🗑
|
||||
| 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)
🗑
|
||||
| show | interaction: transmission & absorption ; effect: photoelectric (=image producing)
🗑
|
||||
| 10. The inverse square law discusses the relationship between which two factors? | show 🗑
|
||||
| 11. List the properties (characteristics) of diagnostic radiation x-rays. | show 🗑
|
||||
| 12. Besides the photoelectric effect, name and describe 2 other photon interactions. | show 🗑
|
||||
| 13. Define the term "attenuation". | show 🗑
|
||||
| 14. List the items found on modern control panels. | show 🗑
|
||||
| show | High heat storage capacitor, high heat dissipator, and high atomic number
🗑
|
||||
| show | aperture, cones, shutters, cylinders
🗑
|
||||
| show | kVp, ma & time, filtration, distance (SID, OID)
🗑
|
||||
| show | DC (Direct Current)
🗑
|
||||
| 19. What part of the x-ray circuit provides the direct current to x-ray tube? | show 🗑
|
||||
| show | On the cathode side, filament creates electrons that have a negative charge. High voltage generator starts the rotation of anode (positive side). Once electrons interact w/ tungsten target creating protons therefore making useful beam.
