recorded detail

QuestionAnswer
recorded detail is the degree of geometric sharpness, definition and the accuracy of the structural lines actually recorded in the radiographic image
the unit of resolution in film/screen imaging is line pairs per milimeter
poor resolution is caused by inacceptable levels of penumbra
which can negatively impact recorded detail involuntary motion
factors affecting recorded detail include focal spot size
resolution is improved when OID decreases and SID increases
spatial resolution in digital imaging is determined by bit depth, matrix size, and pixel size
as focal spot size decreases, umbra is improved, penumbra decreases, and resolution increases
penumbra decreases as focal spot decreases, OID decreases, and SID increases
slow film-screen combinations increases resolution
resolution with intensifying screen will increase as __________ increases phosphor concentration
the best method for controlling motion when the patient is unable to cooperate is to maintain mAs, while decreasing time
as a last resort, which human immobilizer is used to hold a patient in position the male relative
which measures the accuracy of an image compared to the original object on a scale of 0 to 1 modulation transfer function
when evaluating the degree of resolution on an actual radiographic image, an effective tissue to analyze is bony trabecular pattern
as the spatial frequecny of objects increases, MTF decreases
for a general radiography, an MTF value of 1 is theoretically impossible
imaging noise is different from quantum noise in that imaging noise is inherent in the imaging system

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
