Focal spot definition

Focal spot means the area projected on the anode of the x-ray tube by the electrons accelerated from the cathode and from which the useful beam originates.
Focal spot means the area on the anode of the x-ray tube bombarded by the electrons accelerated from the cathode and from which the useful beam originates. Also referred to as "Actual focal spot."
Focal spot means the primary source of x rays produced at the location where the anode of an x-ray tube intercepts the electron beam.
