ADVANTAGES OF A CCD COMPARED TO CONVENTIONAL FLUORO
Give this one a try later!
1. High spatial resolution
2. High signal-to-noise ratio/better contrast resolution because of less
noise
3. High detective quantum efficiency (greater sensitivity to light)
4. No warm-up required
5. No lag or blooming
6. No spatial distortion
7. No maintenance
8. Unlimited life
9. Unaffected by magnetic fields
10. Linear response
11. Lower patient dose
, Spatial resolution is limited by pixel size.

Pixel Size = Image intensifier size (input)/
matrix
*** Note - a 1024 x 1024 image matrix is sometimes described as a 1000-line
system
Advantage #2
Post Imaging Processing

temporal filtering)
In Digital Fluoroscopy the spatial resolution is determined by both
