X-ray production
Updates to Article Attributes
X-rays are produced due to sudden deceleration of fast moving electrons when they collide and interact with the target anode. In this process of deceleration, more than 99% of the electron energy is converted into heat and less than 1% of energy is converted into X-ray production-rays.
Definitions
Cathode
CathodeThe cathode is the negative terminal of the x rayX-ray tube.It is tungsten filament and when current is flown through it, the filament gets heated and start emitting its surface electrons by the process called thermionic emission.
Kilovoltage
High voltage is applied between cathode and anode. HighThe high voltage of kilovolt range (1000 volts) causes electrons to move towards the positive terminal of the tube at a velocity of half the velocity of light.
Anode
It is the positive terminal of the tube. It is made of tungsten disc in ordinary diagnostic x rayX-ray tube and molybdenum in mammography x rayX-ray tube. Fast moving-moving electrons interact with the anode in following ways:
- interaction with K-shell electron: causes the production of characteristic radiation
. - interaction with nucleus: causes bremsstrahlung radiation
. - interaction with outer shell electrons: causes line spectrum
.
