Ultrasound is used to produce images of many parts of the body using sound
waves that reflect or echo back off internal organs of the body. The high
frequency sound waves are passed through the body by a device called a
transducer that is pressed gently against the skin. These sound waves
are converted into real-time digital images that are interpreted by the
Ultrasound does not use any type of radiation in order to produce the digital
images which makes it a safe alternative for imaging during pregnancy.
All Ultrasound procedures are performed with the patient changing into
a procedure gown and laying on a procedure table. The sonographer (person
performing the procedure) will place a small amount of gel on the skin
to prevent air from getting between the skin and the transducer. The sonographer
then moves the transducer over the skin and you may feel a slight pressure
as the transducer is moved. This movement is what is producing the sound
waves that generate the digital images.
Obstetrical (OB) ultrasound examinations may involve the use of a transducer
that is inserted into the vaginal canal. If this is required, the sonographer
will completely explain the process to you in advance.
During the examination, it is important to stay as relaxed as possible
and follow the instructions given to you by the sonographer. This will
ensure that the best images possible are obtained for interpretation by

dietary restrictions and may involve the drinking of water prior to the
