1. Quantum mottle
Answer:
Radiographic noise produced by the random interaction of x-rays with an
intensifying screen
More noticeable when very high rare earth systems are used at a high kVp, high film
speed
2. A short focal-film distance results in what?
Answer: A darker film
3. Information required on a radiographic film
Answer:
Name and address of hospital Date (day, month, year)
Name of client and patient Age, sex, and breed of patient
4. Bucky
Answer:
A moving grid that limits the amount of scatter radiation reaching a radiographic
image receptor, thereby increasing image contrast
Since grid moves, grid lines are not seen and image is clearer
5. Collimator
Answer: A device which restricts the beam of x-rays as they leave the x-ray machine
6. kVp
Answer: Peak kilovoltage High voltage circuit
The "quality" factor
Controlsthe penetrative ability ofthe beamand thus affectsthe radiographic contrast of
the x-ray
7. mAs
Answer: Milliamperage per second (mA x time in seconds) The "quantity" factor
Controls the amount of photons produced and thus the radiographic density
8. Scatter radiation
Answer:
Increases with increased kVp

Bij Knoowy vind ik notities van vakken die mij helpen bij het leren.
Goed voor als je een samenvatting nodig hebt of de leerstof niet zo goed snapt, maar ook voor als je bijles nodig hebt.
Tijdens mijn studie aan de Arteveldehogeschool en KU Leuven heb ik opdrachten gemaakt die ik nu via Knoowy deel met andere studenten.
Knoowy is een zeer goed platform voor samenvattingen en ik zou het aanraden.
Het is een fijne en uitgebreide website met helpende documenten en samenvattingen!
Uitgebreid aanbod en zeer gebruiksvriendelijk! Al meerdere malen gebruik gemaakt en zoals steeds tevreden.
Prima ervaring, vlotte betaling, alles vlot kunnen downloaden Zeker voor herhaling vatbaar.
De website is gebruik vriendelijk, je krijgt meteen de samenvatting na de betaling. Aanbevolen!
