Ultrasound Frequency Variances
for Diagnostic Imaging

The world of medical imaging devices is ever changing. Case in point: more and
more portable ultrasound machines are being used in a wide variety of
applications—and for good reasons. They’re extremely easy to use, portable,
lightweight, compact and deliver good quality images. Their portability makes them
very convenient, and their batteries deliver long life both on and off site.
Portable ultrasound machines are available in a wide range of frequencies, from 3-
20 MHz, making them suitable for a wide range of applications, from Abdominal,
Nephrology, Orthopedics, Podiatry and Rheumatology to Gastroenterology,
Cardiology, Urology, Vascular/Peripheral vascular and more.

Let’s take a look at the variances of ultrasound frequencies in portable radiology
equipment.
Sound waves are a type of mechanical energy that can be used to produce
images of our bodies’ internal structure and organs through ultrasound
technology. However, sound can’t travel without a medium and the velocity of
sounds waves don’t remain constant. A sound beam becomes narrower and
more directional with an increase in its frequency. It’s also important to note
than the frequency of sound waves have to be inversely proportional to their
penetration. The penetration of a sound wave decreases with an increase in
frequency, and vice versa.

When sound waves pass through a medium, it causes vibrations in their
molecules. When the molecules expand and contract, the motion of sound
waves pass from one molecule to the next.
The velocity of a sound wave isn’t constant. It changes with the compressibility
of the medium through which it travels and is directly correlated with the
firmness of the medium. Gases have the highest compressibility, solids have the
lowest and liquids fall in between. When a sound wave passes from a liquid into
a gas or from a gas to a liquid, its velocity increases, regardless of the frequency.

In order to help medical imaging professionals select the right ultrasound
frequency for imaging a body part, they need to keep this in mind: High-
frequency sound waves are absorbed easily and have shorter wavelengths than
low frequency sound waves, so they can’t penetrate as deep as low-frequency
waves. As a result, higher ultrasound frequencies are typically used to image
superficial body structures and low ultrasound frequencies are used to scan
deeper organs and structures.
All portable ultrasound machines come with a probe or scanner that is to be
placed on area of patient to be examined. A gel is applied to area for easy
transmission of sound waves. A diagnostic ultrasound transducer can operate at
more than one frequency.

Here is a guide to the frequencies and the body parts:
2.5 MHz: obstetric, gynecological and deep abdomen imaging
3.5 MHz: obstetric, general abdomen and gynecological imaging
5 MHz: vascular, breast and general abdomen imaging
7.5 MHz: breast and thyroid
10 MHz: thyroid, breast, superficial masses and veins and musculoskeletal
imaging
15 MHz: musculoskeletal and superficial structures imaging
