Question

What is the maximum size a treatment area can be when performing US relative to the ERA (electric radiating area) in the sound head?

1) Smaller than the ERA of the sound head
2) Way too small of an area to perform US sound and would cause possible burns
3) Way too big of an area to perform US on and therefore it would not be useful in providing any beneficial effects
4) 2-3 times the size of the ERA of the sound head

Answer 1

The maximum size of a treatment area when performing ultrasound relative to the ERA of the sound head is 2-3 times the size of the ERA of the sound head.

Step-by-step explanation:

The maximum size of a treatment area when performing ultrasound (US) relative to the Electric Radiating Area (ERA) of the sound head is 2-3 times the size of the ERA of the sound head.

It is important to have a treatment area that is larger than the ERA to ensure that the therapeutic effects of US are delivered to the targeted tissue without causing burns or other tissue damage.
