Question

Quizplus · Accepted Answer

Focal spot blooming occurs when a high amount of electrons are forced onto a small focal spot for an extended period of time, causing the electrons to scatter and create a larger effective focal spot size. This can happen with high mAs settings, but not necessarily with high kVps or large SIDs. Extreme tube angulation may have other effects on image quality, but it is not directly related to focal spot blooming.
