The dimension of the focal spot is determined mainly by the dimension of the beam of electrons arriving from the cathode. In many x-ray tubes, the focal spot is rectangular and the dimensions of focal spot ranges from 0.1 mm to 2 mm.

I have recently worked with x-ray tube and hence can explain you the generation of x-rays. An X-ray generator is used to generate X-rays. X-ray imaging system includes an X-ray source and an image detecting system. The X-ray tube emits electrons (from cathode tungsten filament) towards a rotating anode disc. The point where the electron beam strikes the target is known as focal spot. X-rays arise from the target anode disc at right angles and are then focused by a collimator and then the images are received. Upon receiving the images, they are viewed on a photographic plate.

X-ray machines operate by applying controlled voltage & current to the X-ray tube. This enables you to control the X-rays by controlling the voltage or current. The beam is then projected on the object. While some beams through the object and some others are absorbed. The resulting radiation is then detected in a photographic film.
