Lesson 1 Flashcards
a machine that contains an evacuated vacuum glass cylinder called?
X-ray machine
3 parts of x-ray machine
- x-ray tube
- control panel
- high voltage section
evacuated glass envelope that generate xray
xray tube
main parts of an xray tube
cathode - negative side
anode - positive side
responsible for producing electrons when heated
filament
parts of cathode
- filament
- focusing cup
a metal cup wherein the filament is embedded
focusing cup
emission of electrons when heated is applied
thermionic emission
parts of anode
- target
- focal spot
tungsten material embedded in copper, rhenium, molybdenum, and or graphite
target
small area of the target being hit with electron
focal spot
reasons why tungsten is used as target material
- high atomic number (74)
- has a high melting point (3,410*)
- high thermal conductivity
two types of anode x-ray tube
- stationary anode
- rotating anode
a vacuum tube or diode made of PYREX glass to enable it to withstand tremendous heat
glass envelope
electric motor which works on the principle of electromagnetic induction
induction motor
located outside the glass envelope consisting of a series of electromagnets equally spaced around the neck of the tube
stator
located inside the glass envelope compose of a shaft made of bars of copper and soft iron fabricated into one mass
rotor
it starts off in the cathode side of the x-ray tube where the filament is heated to give off a cloud of electrons
x-ray production
the section where you manipulate the x-ray machine to provide technical factors necessary in the production of an
x-ray.
