Q

Ultrasound Function

A

-deep heating 5cm
-piezoelectric crystals vibrate to produce sound waves into tissues through transucer
-most waves reflect, need gel or water

Q

Ultrasound Absorption

A

-penetration and absorption inversely related
-absorption increases with frequency
-high protein=high absorption

Bone: highest
Blood: least

Q

Ultrasound Frequency

A

0.75-3MHz
-tissue depth

1Mhz= greater depth, 5cm
3MHz= superficial 1-3cm

Higher frequency= faster heating= shorter treatment
