IMAGE PROCESSING CCD AND CMOS QUESTIONS
AND ANSWERS
If the field of view is extended, the matrix size will not be altered.
One of the key distinctions between CMOS and FPD technology is: - ANSWER A.
Electrons move from the plate to the ADC in FPD via a data line.
B. The electrons flow out of the plate through a separate ADC per pixel in CMOS.

square.
CCD technology is employed in which of the following situations? - ANSWER
Telescopes and Satellites
, Which one of the following has the potential to outperform film in terms of detail
and resolution? - ANSWER CMOS
The resolution of ANSWER grows as the matrix size rises.
If the DEL is increased, the patient's dose will decrease.
When was CMOS developed? - ANSWER Early 1960s.
Which of the following best describes a pixel in an FPD plate? - ANSWER A
square with two tiny squares at opposing corners.
Which of the following uses the "bucket brigade"? - ANSWER CCD
In CCD technology, fiber optics carry light photons to the photodiode.
