How Does Ultrasound Therapy Work?

Definition
Ultrasound; acoustic wave vibrating at frequencies over those that the human ear can hear, more than 20,000 cycles per secondly (hertz, Hz).
Healing ultrasound is that which is made use of for healing (instead than diagnostic) purposes as well as is usually produced at 1 million cycles per second or 1 megacycle (MHz). Typically United States frequency is in between 0.7 as well as 3.3 MHz.

Introduction
Ultrasound was very first investigated in Europe as well as was introduced to the USA in the very early 1950′ s, given that this moment, using ultrasound has grown, and it remains a preferred technique today.

Mechanism of action
United States is produced by a high-frequency rotating current being applied to a crystal made of quartz or an artificial (i.e. barium titanate or lead zirconate). The resonance energy is moved to a metal plate, generally nickel-plated brass, and also then the individual’s tissue.

Physical residential properties
It is not sent via a vacuum
It is transmitted poorly via gases
It is sent best via gas-free liquids and also high-density solids

The console
Similar to a radio transmitter.
Has an oscillator that produces electro-magnetic wave at high frequencies.
Transducer head
Transforms electro-magnetic waves into audio waves.
Larger transducer surface area is better (7-13cm *), yet small enough to preserve skin contact.
Waves are emitted in a cylindrical beam perpendicular to traducer surface. Hold the transducer head parallel to tissue surface.
Never permit the beam to fire right into the air without gel or water as this may damage the crystal.

To check crystal: water on the head, show up the strength the water ought to stream.

Combining representatives
Air does not perform well, must use a combining medium. Use a business gels, not mineral oil as well as some gels will certainly contain materials that can promote healing such as, vit E, aloe.

Attenuation
As United States takes a trip with human tissue, it progressively decreases in strength due to attenuation. Attenuation is the outcome of absorption, refraction and also representation, with absorption accounting for concerning half of depletion.

– Healthy proteins are the major absorbers of United States
– Boost protein web content increase absorption
– Tissues with high water web content reduction absorption (waves pass via).
– Homogenous tissues decrease absorption (fat).
– Heterogeneous tissues, fascia aircrafts enhance absorption.
e.g. bone periosteum, fat muscle mass, diff muscle mass teams.
– Bone reflects waves, which satisfy incoming waves: resonance consequently heat manufacturing (periosteal burning).
– Metal artefacts mirrors waves yet take in warm for that reason care.

Absorption.
Conversion of the URL mechanical power of US right into warm is shared as an absorption coefficient and is reliant on tissue kind and also regularity. This coefficient is revealed in decibels/cm and is greatest for cells with the титаниум гел оценки highest possible collagen material and boost symmetrical to the United States frequency.

United States is кликнете върху следната уеб страница produced by a high-frequency rotating current being applied to a crystal made of quartz or an artificial (i.e. barium titanate or lead zirconate). The present causes the crystal to flex, first in one instructions as well as then the various other, as the present alternates. This contortion of the crystal develops what is called piezoelectric power. The resonance energy is moved to a metal plate, usually nickel-plated brass, as well as then the client’s tissue. The crystal and also metal plate are housed in the transducer or audio head of the unit.
