The focal spot size is the size of the area where electrons collide with the anode of the X-ray tube to produce X-rays. It is not necessary to be very sensitive to the focus size for medical or analytical X-ray tubes. However, for magnified observation of small parts, selecting an X-ray tube with a microfocus size is required.
For details, see the technical column "What is Microfocus X-ray (Basic Knowledge)" and
the technical tips "X-ray Nondestructive Inspection Series (1) X-ray CT How to take a clean image?". Please refer to the "X-ray focus".
