Ultrasound are sound waves that cannot be heard by the human ear. They have frequencies above 20,000 hertz (20 kilohertz) the upper limit of human hearing. Interestingly, dolphins, bats and other animals can hear these extremely high frequencies. A diagnostic ultrasound in radiology (also known as sonography) uses a sonographic scanner that operates in much higher frequencies. Ultrasound, unlike X-rays produce no ionising radiation and is an extremely safe procedure. The ultra sound shows soft tissues, such as movement of the body’s organs and blood flowing through vessels.
An ultrasound exam is performed by a highly skilled sonographer using a handheld transducer (probe)which is placed on or over the skin or inside a body opening. A thin layer of gel applied to the skin acts as a conductive medium. The gel creates a bond between the skin and the transducer to reduce static. It forms a tight connection to prevent air space between the probe and skin. This is necessary in order to create an absolutely clear image of the fetus and occurs through the reflection of soundwaves from body structures. The strength or amplitude of the sound signal, and the time taken for the wave to travel through the body, provides the information needed to produce an image on a computer called a sonogram.
There are many uses of ultrasound in patient care. These include bone sonometry to assess bone fragility; breast ultrasounds to visualise breast tissue; echo cardiogram to view the heart; ultrasound-guided biopsies to collect a sample of tissue; and ultrasound guided needle placement in blood vessels or other places of interest. Radiologists are specialist medical doctors that undertake these procedures.
The ultrasound system used at Armadale Medical Imaging provides the ultimate solution and far surpasses conventional ultrasound performance. The product used is known by the brand name Phillips Epiq Elite Ultrasound. This ground-breaking technology produces a new level of clarity and detailed clinical information. The extraordinary precision and processing power occurs through the capacity of a premium quality ultrasound to capture enormous amounts of acoustic data, resulting in extraordinary real-time images. The end result is elevated diagnostic confidence for both the Doctor and Patient.
