What is the purpose of focusing Cup?

Focal Spot

Bremsstrahlung x rays are produced when electrons interact with the positive electrostatic field surrounding the nucleus of an atom. … Occurs when a high KE electron interacts with an inner shell (normally K shell) electron in one of the anode target atoms, ejecting it from the atom.

Q. How does an X-ray machine generate x rays?

An Xray generator generally contains an Xray tube to produce the Xrays. … An Xray tube is a simple vacuum tube that contains a cathode, which directs a stream of electrons into a vacuum, and an anode, which collects the electrons and is made of tungsten to evacuate the heat generated by the collision.

Q. What absorbs more of the long wavelength radiation?

Water vapor, carbon dioxide, methane, and other trace gases in Earth’s atmosphere absorb the longer wavelengths of outgoing infrared radiation from Earth’s surface.

Q. What is the area of the target called that is struck by electrons?

A focusing cup is a negatively charged, shallow depression on the surface of the cathode of an x-ray tube, which concentrates the electron beam towards the focal spot of the anode. It is typically composed of nickel. The negative charge of the focusing cup helps to accelerate the electrons towards the anode.

Q. What is the base material of the anode disk?


Q. What is the difference between digital X-ray and normal X-ray?

While traditional Xrays are considered safe, digital Xrays produce 80% less radiation than traditional. This means it is highly unlikely you would develop issues from occasional traditional radiation exposure, but it is even less likely with the process used in digital Xrays.

Q. What are the two types of X-rays?

The following are common types of xrays:

  • Abdominal xray.
  • Barium xray.
  • Bone xray.
  • Chest xray.
  • Dental xray.
  • Extremity xray.
  • Hand xray.
  • Joint xray.
