Question 1

Define ultrasound

Answer 1

• Visualization + examination of anatomical parts via high frequency sound waves

Question 2

Answer 2

• Waves emitted from probe → body
• Detection + display of energy reflected off tissue within body
• Different structures = different properties = scatter + reflect sound energy in predictable ways = recognize structures
• Of all techniques = most influenced by skill of operator

Question 3

Give the uses for ultrasound

Answer 3

• Imaging for routine use in OB
• Detect + display flow parameters = vascular imaging
