The X-Ray Tube – RAD SC 1 Lecture

Vocabulary flashcards covering the major components, materials, principles, and failure considerations of the X-ray tube as presented in the lecture notes.

Ceiling support, floor to ceiling support, CR support

What are the external components of an x-ray tube?

Ceiling support

Most common allows, both longitudinal and transverse travel

Floor-to-ceiling support

Tube is attached to a column

C-arm support

Tube is attached to a sea shaped device

Protective tube housing

Lead-lined enclosure that prevents electric shock, limits leakage radiation to ≤1 mGy /h at 1 m, and provides mechanical support and thermal cushioning via dielectric oil.

1 MGY per hour at a distance of 1 m

what is the limit for leakage radiation?

Dielectric oil

Is in the housing around the tube as a thermal cushion

Pyrex glass to resist heat

The glass tube is made out of

Cathode and anode

What’s inside the glass tube?

The focusing cup

What surrounds the filament in the cathode side?

Rotor and amateur

What parts of the induction motor are in the anode side?

The filament and the focusing cup

what are the two primary parts of a cathode

thoriated tungsten

What is the filament made of?

3400 degrees c

The filament can be heated to

Thermionic emission

Electron cloud, Release of electrons from a heated filament forming a space charge cloud.

Focusing cup

Made of nickel and negative charge

Fixed and rotating

The two basic types of anodes

Induction motor

what device spends the rotating anode

Copper molybdenum graphite, and tungsten. CMGT

The anode is made of

High atomic number thermal conductivity high melting point

Three important qualities of the anode target

The actual focus spot

Another word for target

Stator and rotor

Induction Motor consist of two main parts

5-20° 12 is the most common

The angle of the anode Is between

To improve spatial resolution

What’s the purpose of the anode of the tube to be angled?

45 % weaker
