Answer 1

Increased depth and decreased resolution

Question 2

Higher frequency = _______________ depth and ________________ resolution

Answer 2

Decreased depth and increased resolution

Question 3

Frequency correlates to the resolution, where ___________ and ____________ have an inverse relationship

Answer 3

Resolution and depth

Question 4

Why shouldn’t you drop a transducer

Answer 4

They’re really expensive and crystals are very fragile

Answer 5

1. Linear (crystals in line)
2. Sector (convex)
3. Matrix (multiple planes)

Question 6

What are the advantages of a linear (crystals in line)

Answer 6

Superficial structures with rectangle display

Question 7

What is a disadvantage of a linear probe

Answer 7
