6- How to perform an ultrasound

Question 1

How to make sure the ultrasound waves can penetrate into tissue

Answer 1

clip hair
remove dirt and skin oil using alcohol
apply ultrasound gel
ensure contact between transducer and skin

Question 2

Describe a linear transducer

Answer 2

creates a rectangular beam
requires full contact along the surface of the transducer to get a full cross sectional image

Question 3

Describe a curved transducer

Answer 3

creates a triangular beam
requires only a small contact area

Question 4

What is the purpose of a standoff

Answer 4

increases the distance between transducer and the skin
move superficial structures further away from the transducer

Question 5

What do you need to consider when selecting the appropriate frequency for ultrasound

Answer 5

choose the highest frequency possible for the depth of structure you want to see
high frequency= good resolution but not good depth of penetration
