Xray Tube Revised

Electron focusing cup

directs and focuses electrons towards the target area to enhance the efficiency of X-ray production

anode

the positively charged electrode in the X-ray tube, where the emitted electrons collide to produce X-rays. (+)

cathode

the negatively charged electrode in the X-ray tube, composed of a filament that emits electrons when heated (-)

copper stem

supports the anode and serves as a conductor for heat and electricity in X-ray tubes.

filament and electron cloud

the region around the cathode where electrons are emitted and accumulate before being directed towards the anode.

heats up and forms cloud

focal point on tungsten target

the area on the tungsten target where the electrons collide, producing X-rays and impacting image quality and sharpness of the X-ray image.

glass tube

a sealed environment that houses the anode, cathode, and vacuum, allowing for the generation of X-rays.

radiator

a component used to dissipate heat generated during the X-ray production process, ensuring efficient operation and protecting other components.

tube window

the portion of the glass tube that allows X-rays to exit while preventing the escape of electrons

useful xray beam

the X-ray beam that has been filtered and collimated and is directed towards the patient

vacuum

A sealed environment within the X-ray tube where air is removed to prevent electron collisions, allowing for efficient X-ray production

electron cloud

A collection of electrons around the cathode within the X-ray tube, generated when the cathode filament is heated
