Dental Xray Tube (Pictures)

Filament and Electron Cloud

Heats up and forms cloud of electrons around the filament, which is then directed toward the anode to produce X-rays.

electron focusing cup

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

Cathode

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

tube window

the part of the X-ray tube that allows X-rays to exit while preventing the escape of electrons.

useful xray beam

the part of the X-ray beam that is directed towards the patient, providing diagnostic information while minimizing unnecessary radiation exposure.

anode

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

radiator

a component that helps dissipate heat generated during X-ray production, ensuring the tube operates efficiently and safely

copper stem

supports the anode and serves as a conductor for heat and electricity

vacuum

a sealed space within the X-ray tube that eliminates air, allowing for efficient electron movement and X-ray production

focal spot 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 envelope

a protective housing that encases the components of the X-ray tube, maintains the vacuum, and prevents external contamination.

electron cloud

the collection of electrons that form around the cathode in an X-ray tube, which facilitates the generation of X-rays when accelerated towards the anode.
