When changing from single-phase to three-phase, six-pulse equipment, - ANSWERStwo thirds of the
original mAs are required to produce a radiograph with similar density
When going from three-phase, six-pulse to single-phase, add - ANSWERSone-third more mAs.
When changing from single-phase to 3-phase, 12-pulse equipment, - ANSWERSonly one-half of the
original mAs is required.
Going from three-phase, 12-pulse to single-phase requires - ANSWERStwice the mAs.
changing from single-phase to three-phase, 12-pulse equipment; therefore the new mAs should be -
ANSWERShalf the original
The amount of replenisher solution added as a film enters the automatic processor is related to the -
ANSWERS1. size of the film.
2. number of films processed.
Each film passing through the processor solutions - ANSWERStakes with it a certain amount of solution
,Replenishment is also essential for - ANSWERSmaintaining each solution's level of concentration, to
maintain solution activity and avoid chemical fog from exhausted solutions.
One way to determine the quantity of replenisher solution to be added is by - ANSWERSthe length of the
film entering the processor.
A microswitch initiates and terminates replenishment as - ANSWERSit senses the beginning and end of
each film.
Replenishment is also determined by - ANSWERSthe number of films (volume) processed.
The greater the number of films processed, - ANSWERSthe lower the required replenishment rate
Greater latitude is available to the radiographer when using - ANSWERS1. high kVp factors.
2. a slow film-screen combination.

Ribs
2. Vertebrae
3. Shoulder
anatomic parts measuring in excess of 10 cm require - ANSWERSa grid.
The major exception to this rule is - ANSWERSthe chest
The larger the part, - ANSWERSthe more scattered radiation is generated.
Parts generally requiring the use of a grid include - ANSWERSthe skull, spine, ribs, pelvis, shoulder, and
femur.
, osteomalacia, fibrosarcoma, and paralytic ileus (obstruction), result in a - ANSWERSdecrease in body
tissue density.
The technical factors mAs, kVp, and grid ratio have no effect on - ANSWERSrecorded detail.
A radiograph exposed using a 12:1 ratio grid may exhibit a loss of density at its lateral edges because the
- ANSWERSSID was too great
If the grid failed to move during the exposure, there would be - ANSWERSgrid lines throughout.
If the central ray was off-center, there would be - ANSWERSuniform loss of density.
If the x-ray tube is angled significantly across the lead strips of a focused grid, there is - ANSWERSuniform
loss of density (grid cutoff)
Insufficient or excessive distance with focused grids causes - ANSWERSloss of density (grid cutoff) along
the periphery of the image.
An increase in exposure factors is usually required in which of the following circumstances? - ANSWERS1.
Edema
2. Ascites
3. Acromegaly
acromegaly - ANSWERSan increase in bone size and density
The fact that x-ray intensity across the primary beam can vary as much as 45% describes the -
ANSWERSanode heel effect
The anode heel effect becomes more pronounced as - ANSWERSthe SID decreases, as IR size increases,
and as target angle decreases.
