X Rays Physics

Where are the x-rays generated?

• X-ray tube

• Collimator

• Cathode

• Voxel

Where are the electrons emitted from in an X-ray tube?

• Cathode

• Anode

• Anode arm

• Battery

Why does the anode arm rotate?

• To stop it getting too hot

• To focus the x-ray beam

• To scatter the x-ray beam

• To allow the anode to warm up

How are the electrons accelerated in the x-ray tube?

• A voltage between anode and cathode

• Static electricity

• Anode rotates

• Cathode moves

Characteristic radiation depends on the anode's material. It has little medical use. True or false

• True

• False

What causes the emission of the braking radiation?
