Why is digital better?
Potential for
Dose reduction to pt
Low running cost
Computer aided detection
How does it work?
Image captured on sensor - CCD/CMOS then transformed into series of binary numbers which can be displayed on monitor
What does it use?
Photostimuable phosphor = PSP
What is PSP?
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
What is a common PSP?
Barium fluorohalide doped with europium
Big advantage of digital imaging?
Able to manipulate the image to increase its diagnostic value
