Analog to Digital Converter
CCD

What is the function of a ADC - Answer ✔ Converts video signal from analog TV camera
to digital data

What is sampling - Answer ✔ Process of digitizing an analog signal requires dividing the
continuous signal into discrete parts

What is Quantization - Answer ✔ Each sample of a signal is quantized

On the displayed image each pixel is a visual representation of - Answer ✔ Sampling
and quantization

Common matrix sizes for DF - Answer ✔ 512x512 or 1024x1024

,In DF the computer operates with - Answer ✔ Digitized data it received from the ADC in
a matrix format

The CCD is optically coupled to what - Answer ✔ The Output phospor of the ii

Are sampled charges from the CCD Analog or Digital? - Answer ✔ Analog and must be

Name two types of dynamic detectors - Answer ✔ Indirect digital detector
Direct digital detector

How does a Indirect Digital Detector work? - Answer ✔ 1. Scintillators create visible light
when absorbing x ray energy 2.Quantify light into proportional electronic charge

How does a Direct digital detector work? - Answer ✔ Directly converts incoming x-ray
energy to proportional electronic signal

Indirect Digital Detector emits light - Answer ✔ Isotopically which will reduce spatial
resolution

Each photodiode represents - Answer ✔ A pixel or picture element

Indirect Digital Detector cannot - Answer ✔ directly convert x-rays into an electric signal

The Detector Element DEL is - Answer ✔ a type of storage capacitor, that holds
electronic charge until transferred to the computer

Advantages of FPIR - Answer ✔ Distortion Free
Constant image quality
Impoved contrast resolution
High DQE
Unaffected by external magnetic fields
