Production Of Ultrasound Images

During an ultrasound examination, sound waves produced will be reflected by the organ being examined. Using computer image processing technology the reflected waves will be processed to form images of the organ being examined. The resultant images will be displayed on the screen of the machine. These images are digital images. They can be viewed directly on the screen or printed on film or paper. These images can also be transferred to other digital media such as CD, DVD and other suitable storage media.

You will be required to lie down on the examination table with the part of the body to be examined exposed. A transducer with gel on its surface will be moved on the skin surface of the area being examined. Patients may need to change their position from side to side. Images produced will be displayed on the computer screen of the machine. Patients will be able to view the images during the examination.
