Ultrasound is a very versatile technology. It is well-known for its application in the medical world, though it is also now prominent in the cosmetic industry. In this article, we will examine the various functions of ultrasound to determine how useful it can be in regards to looking after our bodies and health.


In the medical industry, there are various categories of ultrasound technology. One of these categories and perhaps the most recognisable is ‘diagnostic ultrasound.’ This is used in baby scans, and to look inside blood vessels or other passageways in the body. Probes emit levels of ultrasound that are inaudible by humans to produce an image of what is going on inside the body whether it is an organ or the movement of an organ of a vessel.

Using a baby scan as an example, a practitioner places a probe on the lower abdomen that emits sound waves. These sound waves penetrate through the skin to the tissues and before being reflected. This is what allows the ultrasound technology to form an accurate 3D image of the inside of the body. As a result of this, medical professionals can use ultrasound technology to find blockages before they lead to more severe problems.

‘Functional ultrasound’ allows doctors to produce a map of various blood vessels and determine the direction of blood flow. This is particularly useful in investigating whether plaque is blocking any arteries. Furthermore, the images produced by ultrasound scans can identify cancerous tissue.

‘Therapeutic ultrasound’ is another category of ultrasound technology. Rather than producing an image, in this case, ultrasound impacts tissues within the skin directly. The heat created by the ultrasound beams affect the tissues, meaning this technology is also useful in treating sports injuries. This type of ultrasound is called High-Intensity Focused Ultrasound (HIFU). Researchers believe that HIFU has the potential to target and destroy harmful tissues and tumours without invasive surgery. As well as this, HIFU could reverse blood clots without the need to go under the knife. Functions of ultrasound in the medical world could soon become endless, giving people more options aside from invasive surgery.


Referring back to HIFU technology as mentioned above, this is now commonly used in the cosmetic industry. An applicator emits HIFU into the skin to target multiple layers to encourage tightening. The HIFU stimulates collagen and elastin fibres within the skin.

We use this technology at Harley Ultrasound for our HIFU Facelift treatment. We use HIFU to penetrate three different depths of the skin; 1.5mm, 3.0mm and 4.5mm. The lowest level of ultrasound reaches the epidermis, the middle level targets the dermis, and the highest level reaches the superficial muscular aponeurotic system (SMAS) layer. HIFU is a revolutionary addition to the cosmetic industry because it can directly impact the SMAS layer in a procedure that is painless and non-invasive. The best factor about HIFU is that it is safe and produces effective results without causing any damage to the skin. In contrast to invasive surgery, you will feel little to no sensation at all. As a result of this, you will gain firmer skin by undergoing absolutely no trauma.


The various functions of ultrasound are truly astounding in their capability to improve and monitor our health. Not only can ultrasound identify problems, but it can go so far as to treat them as well. With more research being conducted surrounding the potential of ultrasound technology, there is no doubt that it will be beneficial in more ways in the near future.
