lesson 4 Flashcards
1
Q
- captures images directly onto digital detectors, leading to faster image processing and availability
- uses flat panel detectors based on direct or indirect
conversion of X-rays to charge, which is then processed to produce a digital image
A
DR
2
Q
uses cassette-based phosphor storage plates
(PSP), which are then scanned by the computerized system into
a digital format for image processing, archiving, and
presentation.
A
CR
3
Q
- The component that transfers the x-ray generated signal for
collection - It Collects the x-ray generated signal so it can be digitized
A
Coupling Element
4
Q
The xray photons are absorbed by the coating material and immediately converted into an electrical signal. NO scintillation phosphor is involved
A
Direct Digital Radiography
5
Q
- Has a two-step process
- x-ray photons hit a scintillator layer, which then releases light photons that then hit an active matrix array that digitizes the
signal
A
Indirect Conversion Digital
Radiography
6
Q
- The percentage of the pixel face that is sensitive to xrays is the BLANK
- approximately 80%
A
Fill Factor
