Definition
Ultrasound; noise waves shaking at regularities over those that the human ear can listen to, higher than 20,000 cycles per secondly (hertz, Hz).
Therapeutic ultrasound is that which is made use of for healing (as opposed to analysis) objectives as well as is typically generated at 1 million cycles per second or 1 megacycle (MHz). Generally United States frequency is between 0.7 as well as 3.3 MHz.

Intro
Ultrasound was very first investigated in Europe as well as was presented to the USA in the early 1950′ s, because this time around, using ultrasound has expanded, as well as it remains a preferred method today.

System of activity
United States is produced by a high-frequency alternating existing being put on a crystal made from quartz or a synthetic (i.e. barium titanate or lead zirconate). The existing creates the crystal to bend, first in one instructions and also then the other, as the existing alternates. This contortion of the crystal creates what is called piezoelectric energy. The vibration power is moved to a metal plate, generally nickel-plated brass, and afterwards the person’s tissue. The crystal and also steel plate are housed in the transducer or sound head of the system.

Physical residential or commercial properties
It is not sent via a vacuum
It is transmitted improperly with gases
It is transferred finest through high-density solids and gas-free liquids

The console
Similar to a radio transmitter.
Has an oscillator that creates electro-magnetic wave at high regularities.
Transducer head
Converts electro-magnetic waves right into acoustic waves.
Larger transducer surface area is much better (7-13cm *), yet tiny enough to keep skin contact.
Waves are produced in a round beam vertical to traducer surface area. Consequently hold the transducer head parallel to cells surface.
Never ever permit the beam of light to fire right into the air without gel or water as this might harm the crystal.

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

Coupling representatives
Air does not conduct well, should make use of a coupling tool. Utilize an industrial gels, not mineral oil and some gels will include substances that can promote healing such as, vit E, aloe.

Attenuation
As US takes a trip through human tissue, it gradually reduces in intensity due to attenuation. Depletion is the result of absorption, refraction and also representation, with absorption bookkeeping for regarding fifty percent of attenuation.

– Healthy proteins are the major absorbers people
– Rise healthy protein web content rise absorption
– Tissues with high water web content decrease absorption (waves travel through).
– Homogenous cells decrease absorption (fat).
– Heterogeneous tissues, fascia airplanes boost absorption.
e.g. bone periosteum, fat muscle, diff muscle groups.
– Bone shows waves, which meet inbound waves: vibration for that reason warmth production (periosteal burning).
– Steel artefacts reflects waves yet absorb warmth as a result care.

Absorption.
Conversion of the титаниум гел цена power people right into warm is expressed as an absorption coefficient as well as is reliant on cells kind as well as frequency. This coefficient is shared in decibels/cm and also is greatest for cells with the титаниум гел отзиви highest possible collagen content as well as increase symmetrical to the US frequency.

United States is титаниум гел коментари produced by a high-frequency rotating present being used to a crystal made of quartz or a synthetic (i.e. barium titanate or lead zirconate). The current triggers the crystal to flex, initially in one direction and then the various other, as the current alternates. This contortion of the crystal develops what is called piezoelectric power. The vibration power is moved to a steel plate, typically nickel-plated brass, as well as after that the patient’s cells. The crystal and also steel plate are housed in the transducer or audio head of the device.
