row by row
advantages of CCD over FDP
fast
compact
inexpensive
modular design
100% pixel is utilized
extremely light sensitive
sturdier
the ____________is created by electrons in CCD.
signal
anything that interferes with the formation of the image
noise
what are three things that contribute to noise
1.scatter
2.electronic interference
3.quantum mottle
what are the 3 different noises in CCD

, statistical noise
dark current
amplification
not enough xrays to start
not enough light photos created
two few electrons
statistical noise
CCD starts working without tradition
over heating the chip
random electrons are stored on the image
dark current
pixels that dont work
amplification
cheaper CC= more defective pixels = more __________________
amplification noise
where are electrons stored in FDP
capacitor
where are electrons stored in CCD
wells
how are FDP and CCD similar
store electrons
electrons are moved out to the computer in both
what is the difference between FDP and CCD
FDP has lines
CCD has wells or buckets
how do electrons move in FDP compared to CCDS
