X-Ray Tube

the physical area of the focal track that is impacted

the positive side of the x-ray tube; serves as a target surface for high-voltage electrons from the filament, conducts the high voltage from the cathode back into the x-ray generator circuitry, and serves as the primary thermal conductor.

consists of the anode, stator, and rotor

permits the calculation of the time necessary for the anode to cool enough for additional exposures to be taken

due to the geometry of the angled anode target, the radiation intensity is greater on the cathode side

the negative side of the x-ray tube; produces a thermionic cloud, conducts the high voltage to the gap between the cathode and anode, and focuses the electron stream as it heads for the anode.

consists of the filament, focusing cup, and associated writing.

a two-filament arrangement within the x-ray tube

the area of the focal spot that is protected out of the tube toward the object being rediographed

glass or metal structure that houses the entire cathode and anode assembly

photons that were not produced at the focal spot; also called off-focus radiation

a small coil of thin thoriated tungsten wire

the portion of the anode where the high-voltage electron stream will impact

the portion of the anode where the high-voltage electron stream will impact

the portion of the anode where the high-voltage electron stream will impact. When discussing a rotating anode, this describes the circular path that will be impacted by the electron beam

the portion of the anode where the high-voltage electron stream will impact

a shallow depression in the cathode assembly designed to house the filament

a very small focal spot; usually a fraction of a mm in size

a type of tube that quickly regulates the flow of electrons, producing x-ray photons

a type of tube that quickly regulates the flow of electrons, producing x-ray photons

a type of tube that quickly regulates the flow of electrons producing x-ray photons

permits the calculations of the time necessary for the housing to cool enough for additional exposures to be made

any photons that escape from the housing except except at the port

used to reduce the effective area of the focal spot

photons that were not  produced at the focal spot; also called extrafocal radiation

the entire cathode and anode assembly is housed within this mental structure

a guide regarding the most common technical factor combinations that can be used without overloading the tube

an anode assembly that turns during exposure

a hollow copper cylinder or cuff that is attached to the anode disk by a molybdenum shaft

as kVp increases, a greater percentage of the thermionically emitted electrons are driven toward the anode

as more and more electrons build up in the area of the filament, their negative charges begin to oppose the emission of additional electrons

an anode assembly that is immobile

induction-motor electonmagnets that turn the anode

the portion of the anode where the high-voltage electron stream will impact

provides a guide regarding the most common technical factor combinations that can be used without overloading the tube

a structure where the primary x-ray beams exits the envelope, which allows less absorption or scatter of photons

the parts within the cathode assembly that connect the elements of the assembly together
