Digital Processing Flashcards
1
Q
Why is digital better?
A
Potential for
Dose reduction to pt
Low running cost
Computer aided detection
2
Q
How does it work?
A
Image captured on sensor - CCD/CMOS then transformed into series of binary numbers which can be displayed on monitor
3
Q
What does it use?
A
Photostimuable phosphor = PSP
4
Q
What is PSP?
A
Storage phosphor that stores the energy of x-ray photons and release it was light in response to stimulation by a laser which released trapped energy as visible light
5
Q
What is a common PSP?
A
Barium fluorohalide doped with europium
6
Q
Big advantage of digital imaging?
A
Able to manipulate the image to increase its diagnostic value
