lesson 4

Question 1

• 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

Answer 1

DR

Question 2

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.

Answer 2

CR

Question 3

• The component that transfers the x-ray generated signal for
  collection
• It Collects the x-ray generated signal so it can be digitized

Answer 3

Coupling Element

Question 4

The xray photons are absorbed by the coating material and immediately converted into an electrical signal. NO scintillation phosphor is involved

Answer 4

Direct Digital Radiography

Question 5

• 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

Answer 5

Indirect Conversion Digital
Radiography

Question 6

• The percentage of the pixel face that is sensitive to xrays is the BLANK
• approximately 80%

Answer 6

Fill Factor
