A projectile electron collides with an inner shell electron of a target atom
Characteristic radiation
kVp × mAs × 1.35 = heat units
Three-phase, 6-pulse, full-wave rectified equipment
kVp × mAs × 1.41 = heat units
Three-phase, 12-pulse, full-wave rectified equipment
Increase in brightness caused by an acceleration of the electrons
Flux gain
The output phosphor is smaller than the input phosphor, resulting in an increase in brightness called
Minification gain
minification gain + flux gain =
total brightness gain
