Ultrasound Machine

Ultrasound is an imaging technique that creates images of internal body structures using sound waves. The images can be used to diagnose and direct treatment for various diseases and conditions. Some ultrasound examinations involve placing a small device inside the body, but the vast majority are performed externally.

Ultrasounds are used to assess foetal development and can detect problems in the liver, heart, kidney, and abdomen. They may also assist with specific types of biopsies. The resulting image is known as a sonogram.

Ultrasound diagnosis is a safe procedure that employs low-power sound waves. There are no risks known. Though a valuable tool, ultrasound is ineffective for imaging body parts such as the lungs and head that contain gas or are concealed by bone. Additionally, ultrasound may not be able to detect objects located very deeply within the human body. To visualise these areas, we may order additional imaging tests, such as CT or MRI scans or x-rays.

During an ultrasound procedure, a gel is applied to the skin over the area being examined. It helps prevent air pockets, which can interfere with the sound waves that create images. This safe, water-based gel is simple to remove from skin and clothing, if necessary. The doctor presses a small, handheld device (transducer) against the studied area and moves it as necessary to capture images. The transducer transmits sound waves into the body, collects the ones that return, and transmits them to a computer, which then generates the images.

At GB Medical, we have an ultrasound machine and can do basic abdominal scans to evaluate any abnormalities in the stomach, for example, the presence of gallstones. We can also do basic pregnancy scanning to establish gestational age during the first trimester, but we are not allowed to do anatomical scans of the foetus for medico-legal reasons.


1Is an ultrasound painful?
An ultrasound is a painless procedure that does not cause any discomfort.
2How long does an ultrasound take?
Ultrasounds are relatively fast procedures, with most taking between fifteen and forty-five minutes to complete, depending on the findings during the exam.
3Is an ultrasound reliable?
Ultrasounds are not always accurate and can be misleading. If there is anything suspicious found in the scan, or if the results are unsatisfactory, further tests will be done.
