What is the Bucky factor in magnification imaging?
What is the Bucky factor in magnification imaging?
- The ratio of focus-to-image distance to scatter fraction
- The ratio of scatter fraction to beam intensity

Magnification Imaging Noise
Magnification Imaging Noise
The noise level in magnification imaging is primarily affected by the beam intensity.
Bucky Factor (Magnification)
Bucky Factor (Magnification)
The Bucky factor in magnification imaging is the ratio of milliampere-seconds (mAs) with scatter reduction to mAs without scatter reduction.
Larger Image Receptor (Magnification)
Larger Image Receptor (Magnification)
