RAD 103 Adler Chap 8

Why do tubes have small & large filament sizes?

• To accommodate the small and large window I the x-ray tube

• To share the tube heating

• To image small and large body parts

• To share tube cooling

What is the target?

• Area through which x-ray leave the tube

• The negative side of the x-ray tube

• Area on the anode struck by electrons

• Area on the cathode struck by elections

What is the effective focal spot size?

• The area struck by electrons

• The area projected on the patient

• The area struck by x-ray

• The size of the filament

What length exposure cord is required for mobile equipment?

• 2 feet

• 4 feet

• 6 feet

• 12 feet

     

  What is the purpose of the oil bath?

• to dissipate heat from the anode

• to cool the window of the housing

• to cool the window of the x-ray tube

• to dissipate heat from the cathode

What is the anode?

• Negative side of the x-ray tube

• The window of the x-ray tube

• A part of the tube housing

• Positive side of the x-ray tube

What is the stator?             What is the stator?  What is the stator?

• The housing of the x-ray tube

• A series of electromagnets.

• The stator is used to focus the electrons

• The stator is the rotating part of the anode

What length exposure cord is required for mobile equipment?

• 183 feet of 6 cm

• 102 cm or 40 inches

• 15 cm or 6 inches

• 183 cm or 6 feet

What are the 3 key exposure technique selections

• kVp

• mAs

• APR

• SID

1.                   What is fluoroscopy?

• Fluoroscopy isa machine that can travel to patients who are too sick to come to the x-ray department

• Fluoroscopy is a form of nuclear medicine imaging
• Fluoroscopy uses a continuous X-ray beam to create real-time moving images of the internal structures of a patient's body.

• Fluoroscopy involves the use of sound waves to create images
