charge-coupled devices (CCDS) - answer The oldest indirect
conversion digital radiography systems used ________ to acquire the
digital image.
scintillation/ lenses or fiber - answer In a CCD system, x-ray photons
interact with a ______ material and the signal is transmitted by _____
or _____ optics to the CCD.
size/ light to electrical charge - answer During the transmission
process, the lenses reduce the ____ of the projected visible light
image and transfer the image to one or more small capacitors that
convert ______ to _______.
analog-to-digital converter (ADC) - answer This charge is stored in a
sequential pattern and released line by line and sent to an
___________.
photosensitive receptor - answer A ___________ and electronics
embedded into a substrate material in a silicon chip make up a CCD.
Incident light - answer _________ from a scintillator strikes the
detector and electron/hole pairs are produced in the silicon.
, light - answer The number of electron/hole pairs is related to the
amount of ______ that is absorbed.
electrostatic forces - answer The electrons are held by _______ in the
array until the charge is read out to from the image.
polysilicon layer, silicon dioxide layer, silicon substrate - answer The
chip is made up of a ______ layer, _____ layer, and a _____.
polysilicon - answer The _______ layer is coated with a photosensitive
material and contains electronic gates.
silicon dioxide/ silicon substrate - answer The _______ layer is an
insulator and the _____ contains the charge storage area.
detector element (del) - answer Each pixel or _______ contains three
electrodes that hold the electrons in a electrical potential wall.
voltage gates/ electrons - answer The dels are formed by _______
that, at readout, are opened and closed like gates to allow the flow
of _____.
readout row/ "bucket brigade scheme" - answer To collect the
charge on the silicon chips, the voltage sign is changed on the
electrodes within each del, moving the electrons by rows down the
columns until the _______ is reached. This is known as what?
amplifier - answer Once the readout row is reached, the data are
sent sequentially to the sense _____ and are then digitized.
