Focal spot x-ray
WebNov 21, 2024 · To summarize, x-rays are produced in a standard way: by heating a filament, which releases electrons by thermionic emission, accelerating electrons with a high voltage and allowing them to collide with the focal spot on the target/anode. X-rays are produced via two interactions in the anode. Bremsstrahlung x-rays http://www.sprawls.org/ppmi2/BLUR/
Focal spot x-ray
Did you know?
WebThe electrons are boiled off from a cathode and pulled from the cathode to the anode by the tube potential (i.e. the kVp). As discussed above there are typically multiple physical focal spots on an x-ray or CT system where the size of the electron beam is determined largely by the size of the filament (where the electrons are boiling off). WebDec 23, 2024 · The focal spot is the area of the anode in an X-ray tube where the electrons from the filament hit the anode disc from where the …

Other manufacturers feel that there’s a cutoff around 100µm in order to be considered a microfocus.

WebThe focal spot size is an important factor in the system's ability to produce a sharp image. See the information on image resolution and geometric unsharpness for more information on the effect of the focal spot size. Much of the energy applied to the tube is transformed into heat at the focal spot of the anode.
