Noise
This type of noise will occur by the lack of light photons from the scintillator
What is statistical noise?
The number of electron/hole pairs is related to the amount of
What is light that is absorbed?
What is a scintillator?
This compares the strength of the desired signal to background noise
What is signal-to-noise ratio (SNR)?
This layer in the CCD chip contains the electron gate
What is polysilicon ?
The oldest indirect-conversion digital radiography systems used ________ to acquire digital images
What is charge-coupled devices?
This type of noise is common in digital systems and the detector efficiency is directly related to the cost of the CCD
What is amplification noise?
This layer is the insulator in the CCD chip
What is silicon dioxide layer?
This type of scintillator is unstructured due to its powder-like grains
What is Gadolinium oxysulfide (Gd2O2S)?
This type of noise adds unnecessary information to the image. It occurs when the CCD chip operates without radiation stimulation.
What is "Dark" Current Noise?
This contains the charge storage area in the CCD chip
What is the silicon substrate?
This type pf scintillator is structured due to its needlelike crystals
What is Cesium iodide (CsI)?
This evaluates how efficiently an imaging system converts incoming radiation into a useful signal relative to noise
What is Detective Quantum Efficiency (DQE)?
X-ray photons interact with a ______material, to transmit signals by the lenses or fiber optics to the CCD
What is scintillation?
Pixel fill is greater with CCD's than with CMO's
True or False Pixel: Pixel Fill is greater with CCD's than with CMO's
What is True
